Verify your guitar is setup well - no fret buzzing , and GK String Sensitivity is set for uniform response across all strings and for your style of playing - set the proper settings of:


* Low Velocity Cut

and

* Nuance

Learn about those and more by reading all GR-55 docs here

QuoteThere's a related limitation that you can't use the GR-55 as an audio interface for Guitar Rig or Amplitube as you can't mute your guitar's input in the GR-55 and send it to your computer (you will always hear your raw guitar in addition to the computer processed sound).

Prior to using the GR-55 as an audio interface for Guitar Rig or Amplitube, be sure to perfom this important step:

In the GR-55 USB Settings, disable "Direct Monitor"

Faster Scrolling Tip

For anyone delving into the deeper editing, a tip for navigating menus a bit faster (sorry if this obvious to most folks).

Theres some pretty extensive options when in the deeper editing screen for the PCM tones. To quickly scroll down, hold the down arrow and then hold the top arrow simultaneously. You can do the reverse to scroll up super fast.

How to make the GK-3 three-way switch work like the GR-20, when connected to the GR-55:

QuotePaults wrote>
1) Go to System

PEDAL/GK CTL (enter)

Tab over to VOL
    If you want to be able to hear the normal guitar when your switch is in the "GUITAR" position, change GK VOL to "TONE VOLUME", and turn NORMAL PU "OFF".  With the switch in MIX, you'll hear both the GK knob output, and your normal guitar output, with independent control for each.  In GK position, you'll just hear COSM/PCM sounds, and in GUITAR, just the normal guitar.

The other advantage to "TONE VOLUME" is it lets the guitar models be much more responsive and expressive.

The GK settings can also be changed per patch, but this is based on the factory settings. I'm used to having my VG set up this way, so this setting may stay global for me.

Post by: Elantric on February 17, 2011, 01:36:50 AM
Using the Nuance parameters (owners manual page 28)

The Nuance parameters detect when you play your guitar/bass with a soft touch, and apply a corresponding change to the sound of the
PCM tone.
For example, if CUTOFF NUANCE SENS is set to a positive "+" value, the cutoff frequency of the PCM tone will be lowered when you play a
muted or a finger-picked note, producing a softer tone quality.
As another example, you might use PCM TONE 1 to create the sound that will be heard when you pluck the string with a pick, and PCM
TONE 2 to create the sound that will be heard when you pluck the string with your finger. Then set the Nuance parameters as follows,
allowing you to switch between PCM TONE 1 and 2 by alternating your performance technique.
• PCM TONE 1 settings
TONE CATEGORY/NUMBER: the tone sounded for a note played with a pick
LEVEL NUANCE SENS: +50
• PCM TONE 2 settings
TONE CATEGORY/NUMBER: the tone sounded for a note played with your finger
LEVEL NUANCE SENS: -50
To enable the Nuance parameters, turn NUANCE SW "ON" and adjust each NUANCE SENS parameter as desired.
If you want to adjust the nuance so it's appropriate for the guitar or bass you're using, set the SYSTEM - GK SETTING parameters NUANCE
DYNAMICS and NUANCE TRIM (p. 75).

GR-55 Guitar to MIDI Controller setup
https://www.vguitarforums.com/smf/index.php?topic=3787.msg25564#msg25564 (https://www.vguitarforums.com/smf/index.php?topic=3787.msg25564#msg25564)

While playing with the GR-55 and and a midi controller, I discovered the two parameters represented in the nice 3d graphic in the EZ-EDIT screen.  These are parameter REVERB | TYPE | REVERB LEVEL for the vertical axis (DRY to WET), and parameter EQ | CHAR | CHARACTER for the horizontal axis (MILD to BRIGHT).  The third parameter, PATCH LEVEL is just that lol...   I tested about 10 random patches and all responded equally to the same parameters under the EZ-EDIT screen.

By the way, all the screens respond to live midi input if properly configured.  Nice.

I used the ASSIGN feature, in the MASTER page for the patch.  CC's 1-31, 64-95 work.  It seems that up to eight parameters can be controlled as such.

With the GR-55 off, press [< PAGE] and [PAGE >], then turn on the unit while keeping both buttons pressed.  After a while you'll see the VERSION screen.

An example of the use of assignments to create a wide-ranging guitar patch

Assign two different COSM guitars to S1
example: Strat & Les Paul

Assign two differents pickups to S2 (you might have to use two assigns depending on your choice of guitars)
example: Rear+Center and Front for a Strat, Rear and Front for a Les Paul

Assign both the AMP Gain and Level to the GK volume (to be able to clean up your sound without losing too much volume)
example: Gain decreases and Level increases when you turn the volume down
 
Assign a Delay "Send Level" to the EXP and EXP ON pedals (to "wet" the sound depending on your needs)
assigning it to both EXP and EXP ON enables you to control the amount of delay whether the EXP Switch is engaged or not

Assign a Chorus (or effect of your choice) "on/off" to the EXP Switch

Assign a Distortion "on/off" to your CTRL pedal

Welcome to the forum, celtic_dude. :)

Quote from: celtic_dude on March 20, 2011, 07:05:32 PM
How do you assign to S1/S2?

The same way you assign to other controllers. :)
(from page 54 of the manual)

1) Edit
2) Assign

Edit: before you try the example below you have to do the following.
1) Edit
2) System
3) Pedal / GK CTL
4) GK S1: PATCH SETTING
5) GK S2: PATCH SETTING


Example: assigning pickups for two different COSM guitars (Strat & Les paul)

Assign 1
Switch: ON
Target: MODEL TONE NUMBER
Target Min: 01 CLA-ST
Target Max: 05 LP
Source: GK S1
Source Mode: TOGGLE
...

Assign 2 (will work when the Strat model is selected with S1)
Switch: ON
Target: MODEL EGTR/CLA-ST,MOD-ST PU SEL
Target Min: R+C
Target Max: FRONT
Source: GK S2
Source Mode: TOGGLE
...

Assign 3 (will work when the Les Paul model is selected with S1)
Switch: ON
Target: Model EGTR/HH,TE,LP... PU SEL
Target Min: REAR
Target Max: FRONT
Source: GK S2
Source Mode: TOGGLE
...

Notice that the two preceding targets are assigned to the same controller (GK S2).
Only one will work depending on which COSM guitar has been selected with S1.
That's what the trick is
. ;)

Just realised the other night that you can change the tempo of the pulsed / Beat PCM tones by adjusting the master BPM.
Makes these tones a lot more flexible.

If you want (and know how) you can adjust this further in the LFO parameters in the individual PCM tones

I found some products online that will let you use your EV-5 and FS-6 with the GR-55 midi ports. The company is called Midi Solutions and they make converter boxes that let you use your foot switches as midi controllers. Both boxes are midi powered and can be chained together. They can be edited via your computers midi port with their software.

Here is the link   http://www.midisolutions.com/ (http://www.midisolutions.com/)

They do look like good products but I personally find the price a bit steep compared to the price of the GR-55. :/

QuoteI personally find the price a bit steep compared to the price of the GR-55.

I agree I stumbled across them online and thought that so many GR-55 users complain about the lack of Controllers and this solution might be worth it to some. Someone might be able to find out how they work and make a cost effective mod for the GR-55.

Post by: paults on April 17, 2011, 11:56:32 PM

Rocktron also makes a small midi switch box with two controller inputs.  It also has bank up/down and one select switch.  One of those would be cheaper than two Midi Solutions boxes, but would weigh more, if that matters.

http://www.rocktron.com/products/controllers/midixchange/ (http://www.rocktron.com/products/controllers/midixchange/)

One caveat: the Rocktron transmits pedal status with each program change. If you want them to work that way, no problem!

I just noticed that if you select a GK Set in Guitar mode (say GK SET 3), when switching to Bass Mode, the same GK SET is set for that Mode as well.
So you can't have a GK SETup 2 for Bass Mode and GK SETup 3 for guitar Mode, without having to change these each time you change modes.
GK SET selections in both modes share the same control - a little dissapointing.

Toby Krebs posted dozens of GR-55 patches he uses at his gig. Each patch uses Multiple Control Assignments for the Expression pedal to allow you to "pan" between rhythm and solo tones withing each patch  - this allow you to use One GR-55 patch per song and circumvent the long mute silence gap that occurs when changing GR-55 patches during a song.

*I should note that the  Metal guys report the GR-55 Guitar Out is noisy when feeding their ultra high gain Tube amps on Lead channel. An external Noise gate pedal in front of the Tube preamp may be required if you play metal.

* For the lowest latency when triggering external Soft synths with the GR-55, many factors are involved and other options exist beyond simply using the GR-55's USB Driver and USB cable.
Instead, try a 5 pin DIN MIDI cable from GR-55 MIDI Out to an external MIDI adapter.

More of a GK2A/ GK3 top thing to know, but I'll repost audiotrax's excellent comment from another thread:

"If there is ONE thing that's critical in getting the Roland technology to track accurately, it's getting that pickup as microscopically close as possible to the strings, without actually touching them."

Post by: Elantric on June 09, 2011, 08:29:51 AM

With ALL Roland COSM modeling systems that perform Alt Tunings - you MUST use headphones.

The natural pitch vibration of the non amplified strings is actually quite loud - and your ear can be fooled into thinking any odd distortions or pitch errors you hear are emerging from the Output Jack of the Roland Gear. 

In most cases, there are no problems with the Roland Gear - but your ears will be hearing a mix of your speakers AND the natural pitch vibration of the non amplified strings on your guitar, and often these are NOT the same frequency.

Folks forget these facts

1995 - Roland VG-8 $2500 - no editor

1997 - Roland VG-8EX $1900 - no editor

2000 - Roland VG-88 $1500 - no editor

2001 - Roland VG-88 V2 $1500 - no official editor, but a french "V-EDITOR" arrives created by Ralph Benchetrit, but never goes beyond beta version 0.51

2007 - Roland VG-99 - $1500 - first GK 13 processor with graphic Editor based on a reworked version of the  "GT-PRO " editor. But development costs skyrocket.

Late 2008 - global economic meltdown  / inflation  = dealer margins lowered as "buy in" costs raised, dealer training materials are rarely implemented to the dumbed down salesforce on the showroom floor and sales for the VG-99 evaporate.

2011 - Roland GR-55 introduced, specifically designed to be a stripped down , lower hardware cost gateway into the Roland 13 pin Modeling world and compete head to head with Line -6 offerings -  no Guitar in, no external expression pedals, no Editor keeps manufacturing cost to bare minimum. but GR-55 as a relatively fast tracking dual PCM Rompler / synth with Guitar to MIDI at $600 street did kill the KMI Stringport.

2013 - GR-55 Price goes up $100 due to further inflation

Read the GR-55 FAQ for the history of Roland philosophy on why no GR-55 Editor -

Back at 2011 Winter NAMM  when the GR55 was released., VanceG and myself had a personal GR-55 tour by the Roland Guitar Product manager ( which is now in three parts @ youtube.

Roland basically stated that the burden of creating editors for their processors was a very high cost , and Roland GR-55 was designed to be a lower cost entry point into the 13 pin world

QuotePuzzling as to why a 3rd party genius had to come up with the editor software while Roland seems to not care.

The reason the Roland GR-55 shipped from Roland without an Editor is  all explained at the 2011 Winter NAMM show  by Peter S, the Roland US Guitar Product  Manager

Elantric: Will there be an Editor?

Peter S: No:

Elantric: (&*^%)  ?

Peter S: Sorry  - live with it. -I don't mean to be blunt but  creating Editing Software on our side frankly is a Huge, Huge endeavor! 

Elantric: I know, but maybe we can hire a Grad School Student to do it?

Peter S: I'll leave it to you ( and VGuitarforums)  - If you chose to,  let me know

Elantric: If you get me the full GR-55 MIDI Spec  - (in the words of Star Trek II's Captain Jean Luc Picard)  " I'll Make it So!"

Post by: Elantric on June 15, 2011, 08:23:04 AM
Remember the GR-55 can boot up in two operating modes

Guitar Mode

Bass Mode

* If BASS MODE is selected, some parameter names are displayed
differently than in GUITAR MODE.
(Example) String numbers "1, 2, 3, 4, 5, 6" --> "H, 1, 2, 3, 4, L."

Once you assign the GR-55 operating Mode type, it will remain in the currently assigned operating mode on every boot.
Out of the box, the GR-55 ships from the factory in Guitar operating Mode, and many guitarist GR-55 owners forget it has a Bass operating Mode.

Here is how to change the GR-55's Operating Mode (See GR-55 Owners Manual - Page 9)

(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Fi412.photobucket.com%2Falbums%2Fpp208%2Felantric%2FScreenShot2013-03-20at70034AM_zps4e5e3a2a.png&hash=9b8c9fa7d81ea565b6dd8811fed784b4aad8ff7d)


Summary of GR-55 Owners Manual E3 "Important Notes:

#1 NOTE! (page 8 )
• To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before
making any connections.
• Switch on the power to all of your equipment before you raise the volume of the amp.

#2 NOTE! (page 8 )
The settings you were editing will be lost when the power is turned off. If you want to keep your settings, you must save your settings before
turning the power off.

#3 NOTE! (page 9)
GK settings are extremely important in order to play the GR-55 with the best possible sound. You must be sure to make these settings correctly.

#4 NOTE! (page 54)
For each patch, you can change the operation that occurs when you operate the pedal or operate the GK controls (p. 61). For details on the parameters, refer to "PEDAL/GK CTL" (p. 55). This is available if the SYSTEM parameter "FUNCTION" (p. 76) is set to "PATCH SETTING." (If unavailable, the display will indicate "**[SYSTEM]**".)

#5 NOTE! (page 63)
If you edit the value of a parameter that's assigned to a controller, and then save the patch, some parameters will be overwritten with the initial state of the controller. This will make it seem as though the edited value has not been saved. To avoid this situation, choose the OFF setting for the PEDAL/GK CTL parameter FUNCTION (p. 55, p. 76) and for the ASSIGN parameter SWITCH (p. 57) of the function being assigned.

#6 NOTE! (page 65)
• Never insert or remove a USB memory while this unit's power is
on. Doing so may corrupt the unit's data or the data on the USB
memories.
• Carefully insert the USB memory all the way in-until it is firmly in
place.
• If the GR-55 is connected to your computer via a USB cable, you
won't be able to use USB memory to play audio files.
• Dimensions of USB memory that can be installed: 60 (length: including
connector) x 26 (width) x 13.5 (thickness) mm or smaller

#7 NOTE! (page 66)
Use a USB cable (sold separately) to connect the GR-55 to your computer.
• This might not work correctly for some types of computers. Refer
to the Roland website for details on the operating systems that
are supported.
• Before connecting the GR-55 to other devices, you must minimize
the volume of all devices and turn off their power in order to
prevent malfunctions and speaker damage.
• Use a USB cable that supports USB 2.0 Hi-Speed operation.
• Use a USB connector on your computer that supports USB 2.0
Hi-Speed operation.
• Turn on the GR-55's power before you start up your DAW software
on the computer. Do not turn the GR-55's power on/off while the
DAW software is running.

#8 NOTE! (page 71)
When the power is turned off, any settings you were editing will be lost. You must save settings that you want to keep.

#9 NOTE! (page 72)
This operation will rewrite all of the GR-55's settings. If you've stored important data in the GR-55, be sure to save the data to separate USB memory before you execute this operation.

#10 NOTE! (page 73)
If important data you've created has been stored in the GR-55, be aware that the data you've edited or created will all be lost if you execute a factory reset. If you want to keep this data, you must save it to USB memory (p. 72).

#11 NOTE! (page 73)
If the GR-55 is set to "BASS MODE," it will return to "GUITAR MODE" (p. 9).

Summary of GR-55 Owners Manual "MEMOS":

#1 MEMO  (page 7)
• Be aware that string buzz due to a warped neck or worn frets, or faulty octave adjustment, can cause problems such as wrong notes being produced.
• This unit does not support 7-string guitars/basses or other non-standard guitars/basses. Check the Web for details about installing GK pickups
• On the Roland website, the "GK-3/3B Installation Tips" page provides an explanation and photos on how to attach a GK pickup. Be sure to take a look! http://www.roland.com/GK/ (http://www.roland.com/GK/)



#2 MEMO  (page 9)
If you connect different guitars to the GR-55 at different times, you can individually save settings for each guitar. For details, refer to "Setting the GK Pickups (GK SETTING)" (p. 69).

#3 MEMO  (page 13)
When tuning a guitar that's equipped with a vibrato arm, tuning one string may cause other strings to drift out of tune. In this case, start by tuning each string approximately, so that the correct note name is shown, and then retune each string repeatedly until all strings are tuned correctly.

#4 MEMO  (page 16)
With the factory settings, you can use the GK pickup [S1]/[S2] buttons to switch banks.

If you select the "Drums" tone category, there will be fewer editable parameters than those listed in this manual.

#6 MEMO  (page 24)
This screen shows the parameters that are marked by a "#" symbol in the parameter list (p. 25 –). The parameters that you can edit will different for each tone.

#7 MEMO  (page 24)
Edit the parameter settings. Use the cursor buttons to select the tone parameter that you want to edit, and use the dial to edit the value.
This screen shows the parameters that are marked by a "#" symbol in the parameter list (p. 25 –).
The parameters that you can edit will differ for each tone.

#8 MEMO  (page 24)
If you want to adjust the overall volume of the patch, use the cursor
buttons to select the PATCH LEVEL field, and use the dial to edit the
value. Value: 0–200

#9 MEMO  (page 35)
ENV MOD SW - ON - Each time you pluck the string, the VCF cutoff frequency will move from high toward low, producing a "wah" effect. Extremely high cutoff frequency settings will make this effect difficult to discern.

#10 MEMO  (page 35)
ENV MOD SW - INV - Each time you pluck the string, the VCF cutoff frequency will move from low toward high, producing an "oo-ahh" that is the opposite of the "wah" effect. Fairly high cutoff frequency settings will make this effect easier to discern.

#11 MEMO  (page 35)
ENV MOD SENS - 0-100 - Adjusts the input sensitivity of the envelope modulation. Higher settings of this value will increase the range of envelope modulation that occurs when you pluck a string softly.
Listen to how the sound is affected while you adjust this parameter. Start with the setting at about "0," and play while you gradually raise the value. Setting ENV MOD ATTACK to "0" will make it easier to hear the change.

#12 MEMO  (page 36)
PITCH DUET  - DUET - If this is "ON," a sawtooth wave at the same pitch as the original sound will be added to the hexa-VCO, making the sound richer.
By setting the hexa-VCO's pitch shift to a PITCH setting such as +/-12 (an octave up/down), +/- 7 (a perfect fifth), or +/-5 (a perfect fourth), you can create thick, synthesizer-like sounds. By setting PITCH FINE to about "+/-5" to slightly skew the pitch shift of the hexa-VCO, you can give the sound greater depth.

#13 MEMO  (page 36)
PITCH SWEEP SW - Turns the Sweep function on/off.
Normally, you'll use Control Assign to control PITCH SW, and use the control to operate PITCH SW.
The Sweep function is effective when you operate PITCH SW to change the pitch shift amount for the hexa-VCO.
It does not operate on changes that occur in the input pitch while the pitch shift amount is unchanged.
SWEEP RISE and SWEEP FALL have no effect if SWEEP SW is "OFF."

#14 MEMO  (page 36)
VIBRATO SW - Turns the vibrato effect on/off.
If you make Control Assign settings to control VIBRATO SW, you'll be able to add powerful vibrato by turning VIBRATO SW "ON" when desired during your performance. * You can't apply vibrato to the hexa-distortion.

#15 MEMO  (page 39)
Edit the parameters. Use the cursor buttons to select the effect parameter that you want to edit. Use the dial to edit the value. This screen shows the parameters that are marked with a "#" symbol in the parameter list (p. 41 –). The parameters that can be edited will differ depending on the effect.

#16 MEMO  (page 39)
If you want to keep the changes you made, save the patch (p. 60). If you want to adjust the overall volume of the patch, use the cursor buttons to select the PATCH LEVEL field, and use the dial to edit the value. Value: 0–200

#17 MEMO  (page 54)
The GUITAR OUT jack can output the normal pickup sound and the sound of the modeling tone.
For example, you can make settings so that the normal pickup sound and the modeling tone sound will be played through a guitar amp, while the other synthesizer sounds will be played through the PA system connected to the OUTPUT jacks. For details, refer to System settings "GUITAR OUT Jack Settings (GUITAR OUT)" (p. 70).
For details on the parameters, refer to "GUITAR OUT" (p. 59). If the SYSTEM setting GUITAR OUT (p. 80) is set to anything other than "PATCH," this setting is ignored.

#18 MEMO  (page 61)
Switch delay on/off by pressing the [CTL] pedal
Make the following parameter settings.
• SYSTEM  - PEDAL/GK CTL
Tab Parameter  Value       Page
CTL FUNCTION DELAY SW p. 76
You should first raise the "EFFECT LEVEL" (p. 52) setting for DELAY.

#19 MEMO  (page 65)
USB Memory Stick Playback - Press the [ENTER] button once again to start playback.
During playback, you can use the PAGE [ ] [ ] buttons to rewind or fast-forward.

#20 MEMO  (page 71)
Changing the Output Sound from the GUITAR OUT Jack for Each Patch
1. Set the system parameter GUITAR OUT–SOURCE (p. 80) to "PATCH."
For details on setting the system parameters, refer to "Settings for the Entire GR-55 (SYSTEM)" (p. 69).
2. Set the master parameter GUITAR OUT–SOURCE (p. 59) to the setting you want to use.
For details on editing the master parameters, refer to "Patch Settings
(MASTER)" (p. 54).

• The setting of the GUITAR OUT jack does not affect the output from the OUTPUT jacks.
If you don't want the output from the GUITAR OUT jack to be included in the sound that's output from the OUTPUT jacks, you must separately set each of the patch's tone settings to "OFF."
• If the GUITAR OUT–SOURCE setting is "BOTH," the normal pickup sound and the modeling tone sound will be mixed and output.
• The OUTPUT SELECT (p. 70) setting does not apply to the sound that's output from the GUITAR OUT jack.

#21 MEMO  (page 74)
PICKUP PHASE - Specifies the phase of the divided pickup and the guitar's normal pickup.
Set this to "NORMAL," and if the low-frequency range is cut, change it to the "INVERSE" setting.
The phase will be easier to detect if the divided pickup sound is mixed with the normal pickup sound.

I read some post this week that got me thinking of some possibilities of the GR-55. the first idea was to switch from a 12 string acoustic model to a Les Paul through a high gain amp.
assign 1 switch guitar models
assign 2 turn the amp on and off
assign 3 turn 12 string on and off

the second idea was to switch amps with a single guitar model.
1 turn on the amp block and turn on the amp sim in the MFX block.
assign 1 switch the path of the modeled guitar from MOD to MFX.

I did not know you could do this and now it has opened new doors for patch creation. Now I can do alot more things within a patch.

Just a side note: the amp sims in the MFX block are week so I recommend use them for clean or low gain amp sounds only.

Tip- use an assign to set the gain and output levels of the amp. That way you can use the amp with the acoustic too.

I've recently started trying to play live Dub-Step and am mainly using the GR55 (I'll integrate the VG99 once I get a US20). It's been quite a challenge programming sounds that are typical of the genre. There is a ton of modulation going on in some of these signature tones like the wobbly bass drops and growling, spitting mid range saws. For a while I wasn't sure I'd have control over all the parameters I want in the way I want.

Basically I needed to figure out how to control assign controllers with other assign controls. I'm trying my best to keep it all "in box" rather than relying on external sequencers or control surfaces.

I realized using the patch tempo in various ways really aides in achieving some of this meta control. Try using the wav or internal pedals for assign control sources and setting their sweeps to divisions of the patch tempo to control various parameters of your pcm tones (like LFO beat divisions) then assign the tempo itself to be controlled by another wav or internal pedal control. This will get you some pretty interesting results and and mix things up quick! I was able to get bass drops that pulsate at various tempos all on their own (that is I didn't have to press any buttons to change tempos).

The nagging thing I've found at this point is that you're limited in how you can trigger when a particular wav or internal pedal controller starts. It would be great if we could turn assigns on or off at will via a midi cc or nuance control or whatever. Or imagine what would be possible if you could re-trigger an internal pedal controller with each plucked note, it would certainly make high level control schemes more efficient to say the least.

I have the feeling if I were to integrate MAX I could achieve the higher level controls I'm looking for. I've only started reading about the capabilities of it's existing modules and it seems like I'd be able to trigger an oscillator, using it as a pseudo "internal pedal", with a note input (either midi are audio). Hell I've heard of people using various colored lights as trigger inputs. Anyone using MAX to control the GR55?

Sorry for the rambling dissertation. The Gr55 (and vg99) are deep units and while I wouldn't say they're deeply flawed it's just that the more I dig the more I wish they could do.

I found some products online that will let you use your EV-5 and FS-6 with the GR-55 midi ports. The company is called Midi Solutions and they make converter boxes that let you use your foot switches as midi controllers. Both boxes are midi powered and can be chained together. They can be edited via your computers midi port with their software.

i am doing my solo thing...i make all my own beats via v-drums and all kinds of loops that i would also add to brennan drum parts

i have more control over the groove as i am also a drummer playing pretty much my whole as well as guitar
so that makes it easier in a club environment...i have 8 tracks of drums with 80 different "beats"
that i can pick and choose from while live looping....much more 'dj" style

BUT!!!!!!
man having a friggin drummer take care of the BEAT and got to do is make and tweek loops ....SOOOOOO much more fun!
i got my eye out for a drummer but fer now solo i go =)

Another top thing to know, especially if you haven't decided whether to buy a GR-55 yet:

It only has one MIDI pitch bend range setting: 24 semitones. You can't adjust that.

Great for some, terrible for others. I find that some of the soft synths in Ableton Live only have a 12 semitone bend range (Analog, for example, and Simpler).

Here are some new ideas that I came up with for setting up various hexiphonic pickups. I recently installed a piezo system on My Les Paul and I disovered some new tricks for setting up the GK settings in the GR-55. It's kinda detailed so I put it into this PDF document.

=====


As we all know we don't all have GK-3 pickups installed on all our guitars and some of us have multiple
guitars with different Pickup systems. I will cover some basic principles I have discovered when I
installed a piezo system on one of my guitars.

Through reading the threads on this topic I have found some useful Ideas and discovered some new
ones. The first rule is set up your GR-55 and any other 13 pin synth or processor so that it knows your
guitar. Set the sale length correctly, if you don't know it you can measure it or look it up on line. Most
guitar sites include the scale length in the details of the guitar. As a rule you should set the correct
pickup type but you can try other types. I use the Fishman setting for my GK-3 pickup; I can EQ it to get a
little better tone from COSM acoustic guitars. The only other setting on the first page that I change is the
Normal Pickup gain, if you dial it back to -4 you will get less noise when using the normal pickups. 

The string distance page is only useful for the tone of your COSM guitars and is only necessary if you
select GK-3 or GK-2A pickups. This setting will not affect tracking or dynamics.

Setting your sensitivities is very important and I have read many threads on the topic. The best results
come from setting the sensitivity as high as you can without passing the last dot on the meter. This
includes Piezo pickups as well. I have read many threads that say to set it to 0. This will provide good
PCM tracking but it will lessen the dynamic response of your playing. If your Piezo pickup still glitches we
can fix this on the next page. Remember these concepts w apply for all pickup types. And applying them
will improve your playing experience.

The next page is the Velocity settings. Now here is the revelation I came up with and you will be amazed.
Lower the Velocity dynamics to about 2. Remember when I said we would fix the glitches from the
sensitivity page that's how you do it. From now on you can set Velocity and play feel per patch in the
Velocity settings.  You have 2 settings here in the patch Velocity curve and level velocity sensitivity.
Every instrument responds differently to your paying and you have to set each one a little different to
get the most out of it. 
I usually set the play feel on the low side also 2 0r 3 is good d play guitar. This setting can be increased or
decreased in each patch with Velocity curve also. 
Low Velocity cut is for those unessential notes from brushing against the strings. Set this above 5 but be
careful because it will cut off any week signal and you will lose some dynamic ability. You can make up
for this by playing every not strong and accurate (if you are anything me this is not possible) or you can
use the legato option. Legato is notes that are tied together (slides, slurs, bends, taps and trills). This is
even helpful for instruments with the chromatic option.

On the Nuance page you can leave it default for piezo pickups but for GK's I suggest setting the Nuance
trim to 8. This will especially help with triggering drums. For some reason the Ab snare drum needs a
little help triggering and it also helps with other tones as well but the drum kits is where it shows the
most. Drums have fewer editing parameters and they can be tricky. You will need to employ a lot of
palm muting to get an accurate performance.

Always keep in mind when using PCM sounds you are no longer a guitar player you are a synth player
and you will need to learn new techniques to achieve a flawless performance.

The topics covered in this article are purely my opinions and feel free to experiment or use whatever
works for you. Remember every guitar is different and no one setting will work for everyone. 

I am ordering an OPT-1 from RMC soon and I will cover my thoughts on what it does and does not
improve. So far everything in my GR-55 is working great without it with the exception of the GR-300
COSM model but I got around that by using the GR-300 PCM.

Side note for Piezo users.... If you use some kind of foam on the other side of your bridge on Les Paul
type guitars it will get rid of that overtone/feedback pitch on COSM guitars.

Jimmy.

I found a new trick to expand your control options in the GR-55 and it will work with any other processor as well. you can use your heel position of your expression pedal as a switch by selecting for example the delay switch as a target parameter. choose your EXP Pedal as the source and set it to toggle. then you act range low to 0 and the act range high to 1 and when your pedal hits all the way down it will turn your delay on and off. this trick can be employed as a momentary control as well and if you want to have it in the toe position set the act low to 126 and the ACT high to 127. you can do this with your GK volume ant have a switch at both ends of the knob. so that will give you 4 more controllers you can use. warning: if you use the toe position as an assign it will activate if you also use the toe switch as an assign.

I came up with this idea in reading one of gumtows posts in which he mentioned this idea in passing while addressing another question, the man is truly a genius.

Using a second guitar with regular pickups on the GR-55

Here's a tip if you want to use a second guitar with the GR-55. The GK-3 is on my steinberger guitar but i wanted to use my stratocaster with my gr-55 wich is impossible because there's no input for a régular guitar, what i did is simply unplug the 1/4 small cord for the GK-3 from my steinberger and plug-in my strat with a regular 1/4 cable to the on the GR-55 input of the GK and Voilà!... Now it's possible to use the normal pickup of my strat in to the GR-55. Plus...Now 2 guitars players can use the GR-55 at the same time! WoW!

Hearing Your Normal (Guitar) Pickup Signal

If you want to hear your guitar's original pickup sound in the GR-55, you need to activate the NORMAL PICKUP switch within each patch. Here's how.

1. Choose a patch to edit.

2. Press the EDIT button.

3. Press PAGE left until you select the TONE menu.
(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Fwww.snapagogo.com%2Fuploads%2Fsource%2F1812013%2F1372710429_2100253340_Tone_Select.png&hash=33b2dc7e0e790f3029bf675e5870e0cdfc0c5219)
4. Press the down-cursor button to select NORMAL PICKUP.

5. Turn the dial to highlight the NORMAL PICKUP box.

6. Set the GK select switch to the MIX position.

Note: If you want to hear only the guitar sound, de-select the PCM1, PCM2, and Model boxes as well.

If desired, press WRITE to save the new setting as a User patch, and then repeat the process for any patch in which you want to hear the original pickup sound.

User Parameters not Saving within a Patch



Some of the factory Preset patches in the GR-55 have the CTL pedal and/or EXP SW assigned to control various functions, for example, the PCM Tone On/Off switch.

An assignment of this nature can make it appear that User parameters are not being stored in a patch. To turn off the pre-assigned CTL and/or EXP SW functions, follow these steps.

1. Select the desired User patch.

2. Press the EDIT button.

3. Press PAGE left or right to select the MASTER tab, and then press ENTER.

4. Cursor left to "PEDAL/GK CTL," and then press ENTER.

Quote"* For the lowest latency when triggering external Soft synths with the GR-55, avoid using the GR-55's USB Driver and USB cable. Instead, use a 5 pin DIN MIDI cable from GR-55 MIDI Out to an external MIDI adapter. all agree that using this type hardware setup will deliver the lowest latency."

Due to many variables, I believe the jury is still out on the best  / lowest latency method for connecting the GR-55 to your computer to drive soft synths.

If its a Mac you are using - avoid OSX 10.8 Mountain Lion if you can.
(Details here)
https://www.vguitarforums.com/smf/index.php?topic=6678.0 (https://www.vguitarforums.com/smf/index.php?topic=6678.0)

But if your iMac is running OSX 10.7 Lion, the Roland GR-55 USB driver works well.

Many Mac folks running OSX 10.5 thru 10.7 report good results using the Roland GR-55 USB Driver for your version OSX and a good USB cable with RF rejection Ferrite cores to a USB 2.0 port on your Mac.

http://www.pccables.com/70509.html (http://www.pccables.com/70509.html)
(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Fwww.pccables.com%2Fimages%2FUSB_20_Cable_6FT_ferrite_core_Black.jpg&hash=2e63cca33ec26d1e876be6939c081ef411b2f98c)


But some systems (not all) do get sluggish and even make the GR-55 Controls run slow after a USB connection is made to a Computer.
A separate Audio / MIDI Interface will typically always be preferred.

If you want a recommendation for a low latency MIDI Interface -the iConnectivity iConnect MIDi is good
http://iconnectivity.com/iConnectMIDI-Overview (http://iconnectivity.com/iConnectMIDI-Overview)
(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Ficonnectivity.com%2Fimg%2FiCM-FrontAngle.jpg&hash=1d0c780c92bd125bb924ac13acd00340f59f9cd1)


Also the MOTU 828MKIII with a Firewire connection is good too

http://www.motu.com/products/motuaudio/828mk3/ (http://www.motu.com/products/motuaudio/828mk3/)

So I will re-phrase that statement to:

"* For the lowest latency when triggering external Soft synths with the GR-55, many factors are involved and other options exist beyond simply using the GR-55's USB Driver and USB cable.
Instead, try a 5 pin DIN MIDI cable from GR-55 MIDI Out to an external MIDI adapter. "

Assign both the AMP Gain and Level to the GK volume (to be able to clean up your sound without losing too much volume)
example: Gain decreases and Level increases when you turn the volume down
 


Hello, I am having a little trouble assigning this particular parameter on the GK volume knob, could you please explain this a little bit more thoroughly as you explained how to assign the two different guitar tones and pickups to the GK1 and GK2 switches?

Thanks a lot.

Yes this is possible.....Go to the patch, press EDIT > curser down and highlight PCM 1 that you use for strings and press ENTER > scroll down to STRING LEVEL (1 thru 6) and set the string levels for each string. I think for what you want, set strings 1,2,and3, to 100, then the rest to 0. For the bass (MODELING) you would do the same but reversed, strings 1,2,and 3 set to 0, and 4,5,and 6 to 100. PCM 1, PCM 2, and MODEL, can all be set up this way or any combination there of. You will need to check PCM 2 in that patch and see what the string levels are set at and adjust to suit your needs. Hope this gets you there. If not, check back and we'll get more detailed if we need to.



GR-Patch writing problems / Control Assignment Conflicts

Some of the factory Preset patches in the GR-55 have the CTL pedal and/or EXP SW assigned to control various functions, for example, the PCM Tone On/Off switch.

An assignment of this nature can make it appear that User parameters are not being stored in a patch. To turn off the pre-assigned CTL and/or EXP SW functions, follow these steps.

1. Select the desired User patch.

2. Press the EDIT button.

3. Press PAGE left or right to select the MASTER tab, and then press ENTER.

4. Cursor left to "PEDAL/GK CTL," and then press ENTER.

5. Cursor down to "CTL FUNCTION," and then turn the dial counterclockwise to select "OFF."

6. Press PAGE right to select the EXP SW tab.

7. Cursor down to "EXP SW FUNCTION," and then turn the dial counterclockwise to select "OFF."

8. Save this new setting into the patch by pressing WRITE twice.

Note: Some patches may also contain assignments in the ASSIGN section that can effect custom stored parameters. If the above steps don't help with your patch, go to the ASSIGN menu, turn off each assignment in the patch, and then save the settings

QuoteHow do I get a blank initialised patch, in order to be able to start from scratch?
See GR-55 Owners Manual Page 60

Here's how to initialize all parameters of a user patch. This is
convenient when you want to create a patch from scratch.
* You can't initialize a preset patch.
1. Select the user patch that you want to initialize (p. 16).
2. Press the [WRITE] button.
3. Use the PAGE [ ] [ ] buttons to select the INITIALIZE tab.
4. Press the [WRITE] button.
The screen will indicate "NOW INITIALIZING..." and the patch will be
initialized.
If you decide not to initialize, press the [EXIT] button.


But most find it useful to determine the Expression Pedal and Control Pedal assigns that work for your specific needs / situation - then Build a "blank"patch with these assigns built in - as a starting point for all patches you build yourself. It goes faster if you learn and use Gumtowns GR-55 Floorboard Editor.
https://www.vguitarforums.com/smf/index.php?topic=2951.0 (https://www.vguitarforums.com/smf/index.php?topic=2951.0)
The USER banks area all have duplicate copies of the same patches found in the Factory Preset area  - so go ahead and create new patches, and over write whatever patches are in the USER patch area.

Review these two patches below as best examples of GR-55 Multi-Control. Due to the long patch delay (gap no sound) that occurs during each GR-55 patch change, many GR-55 users plan ahead use only one patch per song - and carefully design each GR-55 patch, so each can have several sounds available, just by moving the expression pedal or stepping on the GR-55 CTRL Pedal - all within the same GR-55 patch. I suggest try either of these linked below, see which one works best for you - then use one of these multi-control patches below as a starting point for your "GR-55 Blank patch" - which you can edit most effectively using GR-55 Floorboard Editor.

Since the ONLY feature that can be assigned a HOLD function is the CTL pedal, there is no way to apply a hold command while the audio player is in use. This direct from Roland Tech support ( FWIW) The End  :(
    Hi all, this thread is a little old but I discovered something a few days ago that may or may not be news to anyone pertaining to using the HOLD function and still being able to use the audio player. The key is in my quote from Roland " there is no way to apply a hold command while the audio player is in use" BUT, I found you CAN apply the hold function and use the audio player. The key words are "while in use". If you apply the hold THEN turn on the audio player via the little audio player button, the audio player comes on in player mode, and you can use the select up and down, and the start stop functions as normal. However it seems the only way to release the hold while the player is going would be to use the CTL button to put it in the patch view and then change the patch, then go back to your original patch to get back to your original sounds. The audio player continues thru all this. Now, you will not be able to set another hold so there are still limitations but, in the case of my Pink Floyd Shine On patch, it's all I need where as now I can make an accompaniment wave file with the drum track and other backing elements, and continue on into part 2 where the drums come in. As Confucius said " Deer is mo den one way to eat a pussy cat".
  Anyway, still limited but, one less limit discovered and somewhat usable for some purposes. Hope this helps.

Hallo, I have the godin Multiac with GK3 that was pretty good, but now I play a ParkerFly with Graphtec Piezo: on the guitar there are no possibility to change the banks of the GR55 (as it is on the GK3 pickups).. what can I do, if I want fast to change the banks on the fly? I thought I need a Midi Footpedal.. the cheepest that I can get was the rocktron MidiExchange. When I get it I was not really happy, it change only the presets up and down, but here I read it can change also banks?? Can somebode help me how I have to configure the GR55 (or the Rocktron) to get this effect: if I press Up/DOWN of the rocktron, I need to change ONLY beetween the banks, NOT the single presets!??
Thank you!!!

A little more love for the GR-55 flying out from here:
I got the GR-55 because I kinda went full tilt away from straight acoustic with mike and acoustic with fishman (Taylor 314), but I was also wanting to pickup some bass experience.
I chose the GR-55 because of it's dual role modes (guitar and bass) and of course to dive into the whole world of PCM,COSM and effects thru the 13pin interface.
Now last night with my improv group I picked up my bass (a Godin A5 Ultra SA fretless) and forgot to switch modes.
I had a 'Martin Acoustic' patch dialed in.  Hmm guess what, it responded to all the bass strings in Guitar mode (including my low B 5th) and I didn't even bother to tweak the GK settings.  Later I did tune up for better matching the A5's RMC bass piezos.
The original guitar Martin patch had both a #177 (Steel-st.Gt) Model and the Normal PU turned on.  I eventually turned off the Model and just now just use Normal PU.
This setting along with a little bit of reverb and chorus gives a beautiful nice warm resonant fretless sound without reaching down, button-dialing to change modes, switching off and one again.
Love the versatility in the GR-55!

Roland / Boss VG/GT/GR gear has implemented Control Assigns for 25 years

To get the most from the latest Roland gear - Learn how to use those Control concepts from the start by reading the numerous user created docs for the earlier Roland units here:

Roland COSM Reference Library
https://www.vguitarforums.com/smf/index.php?topic=88.0 (https://www.vguitarforums.com/smf/index.php?topic=88.0)

Quotef you want to obtain more incite and better explanations of how Roland gear works - review the OWNERS MANUALS for the earliest examples of current gear.

For example the GR-55 and GP-10 Owners Manuals sinply list all the various FX functions and Control Features, but totally omit any explanation or examples of how to actually use these controls or how they interact.

Here is the 1999 Roland VG-88 Owners Manual  - ITS A MUST READ!  - it lays a better foundation with explanations of how the Internal Wave Pedal and Expression Pedal Min/Max FX range,Assign Hold, etc,  work.

There is a Wealth of Information within the many User created GR-55 Setup Docs which explain in depth how to set "Nuance", "Velocity " etc all GR-55 Owners need to read at link below:

QuoteDescription: I've been compiling notes on GR-55 setups, my own hopefully practical spin on how to set things up. 

The information in the GR-55 manual regarding setting up the unit is pretty minimal.   This doc is meant to supplement the manual with real-world experience.  I wanted to pull together all of the best info I could find in one place, instead of scattered over a bunch of posts in a bunch of forums. 

And, very specifically, I wanted a "cook book", i.e., a specific set of steps to follow to make a setting properly and consistently.

I hope you find this helpful.   Feedback welcome. 

Shawn

9/14, More readable .pdf uploaded.  Changed nuance setting descriptions.

Setup-Nuance - will help you confirm your Nuance is configured well.  If your Nuance is configured correctly, finger plucking will generate bell sounds, and pick usage will generate a steel string guitar sound.
Setup-Velocity - will help you confirm your Velocity is configured well.  It is built from a basic electric piano tone, which varies its timbre with your picking velocity.  Low velocity (picking softly) yields that sweet e-piano tone, almost like a bell.  High velocity (harder picking) yields the growling e-piano tone normally associated with banging hard on the keys.  If you cannot get BOTH tones from your GR-55 depending on how hard you pick, you have probably squished your "Velocity Dynamics" setting too low, and as a result, are not getting all the intended subtleties from the GR-55's tones.

There's an old trick for achieving better GR300 COSM  sound on VG-99 (works for GR-55 and GP-10 too)


Read here:

Optimal GK TYPE Hex Pickup Settings.
https://www.vguitarforums.com/smf/index.php?topic=1060.0 (https://www.vguitarforums.com/smf/index.php?topic=1060.0)
Quote# Hot Tip -  However note that Many VG-99 Patches may work better with a hotter string sensitivity. Often the GR300 emulation functions, or two handed EVH tapping styles respond better with a hotter "GK String Sensitivity" than "20-30" -  - more like "80-100"  - so the trick is  USE A DIFFERENT GK PU Memory Slot, and assign a different GK String Sensitivity setting for each GK PU memory slot. Use those PIEZO PU type memory slots  (even with a GK-3) and program several unique string sensitivities for the same guitar add 2 band EQ to taste.
The GK Settings can be specified individually for each PATCH. Use this setting when switching among multiple STRING SENSITIVITY SETTINGS as you perform.As with everything on the VG-99 - Adjust to taste! There is no wrong way - if it sounds good it is good.

Simply put, midi note + pitch bend = your played tone.  Pitch bend is critical performance data, and is used to capture legato, whammy, and slide as well as bending a note.

If you just delete it, it won't sound right.   

If you use chromatic mode, you won't get the pitch bend data, but you will instead find more extraneous notes.   These may be easier to clean.

FYI, the GR-55 uses the soft pedal CC, CC67, to communicate nuance, or attack velocity.   Low values for pick, higher values for finger style.   I believe notes + pitch bend + CC67 are all the performance data transmitted by the GR-55.

You are encountering one of the GR-55's weaknesses...    Pitch to midi.   

The OTHER thing to check is your pitch bend range, or PBR.   The PBR settings on your soft synth & GR-55 must match.   The GR-55's PBR is fixed at 24.   

Make sure your soft synth is set to 24 also.

There is a lot you can do to improve it, but there are many threads on this forum dedicated to these issues:

An old post but a bit of a revelation playing with USB midi into a Raspberry Pi, same could apply to mac osx.

I found that my GR-55 virtually locked up as soon as the USB cable was plugged in, a patch change took about 30 seconds from the pedals or dial and the menu unresponsive.

The result !!
Some USB midi connections cause a loopback from GR-55 midi out back to GR-55 midi in.
I found if either System setting for Midi PC RX or Midi PC TX is 'off' then the problem goes away.
It is an eternal Program change loopback, the GR-55 does not have the option to have TX or RX program change on different channels.

GR-55 - DIY External MIDI control of GR-55 CTL Hold w/ relay



Quote from: gumtown on January 01, 2018, 12:19:37 PM
I recommend fit an isolation device in the GR-55 (opto-isolator or old fashioned relay).
Justin Morrell wrote >
I know next to nothing about how these work, but from what I understand about an opto-coupler, I would need power to the transmit side from the GR-55.  Since the transmit side would be electronically isolated from the GR-55 CTL pedal, could I then pull the power directly from the incoming 9V DC power supply -- assuming the opto-coupler is rated for 9V?

Would something like this do the trick?

Just a quick update.  I picked up one of those relays I linked in my previous post.  I think they're designed to be used with Arduino stuff.  Anyhow, I wired a 10k resistor across the "in" and "DC+" contacts.  I then wired my 1/4" jack to the "in" and "DC-" terminals.  I pulled 9v DC off of the internal GR-55 power right from where the power supply plugs in (had to pull the board up and wire it from underneath).  I installed the jack on the inside of the USB door, and since it's plastic it keeps the jack isolated from any ground issued within the GR-55.  Of course I also wired the "open" and "common" terminals on the relay board to the terminals at the underside of the CTL pedal.

It works great so far.  I can now trigger the GR-55 CTL pedal remotely from my Boss MS-3 amp CTRL Jack .  Thanks again for your collective input!

For years I've noodled with a minimum of parameters. But finding this site and it's humongous knowledge base and intelligent participants willing to help, I find myself going deeper into my GR55.

Suddenly, I'm not so intimidated.

I am having more fun with the unit now.

Thanks to you all!
👍👍👍👍👍👍👍

I'm using these settings below with much success using my 2012 Godin xTSA (RMC) and stock GR-55 (rev 1.50 firmware ) and Boss GP-10

Thanks Jim Williams!



On both my xTSA'a - the COSM Modleling sounds most excellent .

This is AFTER I follow Jim Williams Piezo Setup.

--
In System, Set the GK PU type to:
PU type ;  PIEZO R
Scale :  ST
PU phase : NORMAL
PU direction : NORMAL
S1/S2 position : NORMAL
NORM PU gain : 0 dB
PIEZO TONE  LOW  :    -2
PIEZO TONE HIGH  :   -3

"DIS"
10.0 mm all strings (does not matter GR-55 ignores this for all Piezo PU selections)

"SEN"
Set the sensitivities for all strings to "50" average (+/-5  - that is all my strings have sensitivity set in the range between 45-55 .
(Note: Godin's older than 2012, might work better with Sensitivity set to "0")

"VEL"
Velocity Dynamics :  2
Play-Feel         :  2 (may vary depending on how you play synth tones)
Low-Velocity Cut  :  8-9

"NUA"
Nuance Dynamics   :  4
Nuance Trim       :  4

"DOW"
Shift   :   0
===============


Be sure you are using Headphones when forming opinion on the sounds  / patches of your Roland gear.!!


Ive voiced prolifically on this forum my preference for GK-3 type pickups for use with Roland COSM Modeling systems , but there have been some minor incremental developments  / improvements in the RMC electronics over the years. I admit bulk of my prior opinions on RMC piezo pickups were based upon a 1998 era RMC Piezo Polydrive 1 install in a Les Paul feeding  a Roland VG-8, where I could always "hear" the underlying RMC piezo characteristics in the VG-8's output, regardless of any patch or tweaking.

In contrast, the GR-55 with firmware 1.50 , and using Jim Williams Piezo setup suggestions

https://www.vguitarforums.com/smf/index.php?topic=3965.msg53317#msg53317

and string sensitivity at an average of "50" for all strings with this new Godin xTSA - the GR-55 sounds wonderful. True the GR-300 preset still has low frequency handling noises and random noises, (the optional RMC OPT-01 sub filter board should cure this) -


In context when using only the 13 pin cable. The Godin's Normal Mag PU"S (Or Mono Piezo Signal  - depending on the guitar volume control settings) will  feed pin #7, on the 13 pin cable where the GR-55 can act as a "GT-100 like" COSM Amp Modeler. All audio output occurs at the GR-55 Stereo Output jacks.
My first order of business was modifying ALL GR-55 User Presets to enable the use of the Godin's Normal pickups and enable use of the three way "Guitar / Mix / Synth" switch on the Godin - and for me, thats where the magic of the GR-55 happens. Many factory GR-55 patches become 300% more useful.
For example, one GR-55 Xylophone patch had a great multitap delay that when used with only straight normal pickups becomes a wonderful world of great tone where the Roland COSM Amp modelling and effects can be appreciated.

I do think the only way to go with the GR-55 is to use an external stereo Volume pedal, and then dedicate the on board GR-55 Expression pedal to "pan / morph" different effects / tones within a single patch. I also find that the xTSA and RMC Piezos and GR-55's Acoustic Modeling sounds very excellent !

But I also notice that with little effort, palm Muting IS possible and get very close to the sound of the Normal pickups.  Finally having a working  "Guitar / Mix / Synth" switch on the Godin  allows instant verification and reality check on the COSM Guitar Modeling and for me opens up worlds of usefulness for the GR-55.
