Title: GR-55 Bug List for submission to Roland Corp.
Post by: jcmidi on February 06, 2011, 07:43:35 PM
Twice while using the Phrase looper and changing patches the unit freezes. Had to restart ,anyone else ? Can't get the RX PC Map
function working. Sending PC from Lexicon MPX floorboard
works fine on fixed but when switched to PROG nothing. Tested another unit same thing. Sent all types of PC from other devices no luck.

Have owned GR500  GR300  GR700  GM70  GR30  GR33

We must try to test  this puppy and I'll get the Bug List to Roland Corp.

Anyone test MIDI Clock Sync for the LFO effects yet?

LEts see if we can make a "Arcane GR-55 Functions that may have Bugs? list!!

Also  - if you post a bug - please edit your own post and provide all the exact details and list the other third party gear you used when seeing this "bug"


EDIT - Just to add some closure for Roland GR-55  - this entire thread of GR-55 Bug List was already submitted to Roland US during Winter NAMM 2012.

As mentioned above,
If a potential bug is found, it is importaint to specify the exact situation this occuring in, so the event can be replicated by Roland.
specify the patch used, the connected equipment, including midi & USB + operating system.
And the sequence of events which led to the problem.

Don't know if I should post this here , or in Q&A.

Anyway, I can't get the Driver to install on XP Home.(want to use Librarian).
The install goes well, until the very end, then it won't let me close the installer dialog box.
The only option is "cancel".
I have uninstalled, and reinstalled 3 times. Same thing each time.
I have tried different usb inputs on the pc, and am following "readme" instructions to the letter.
Does it matter if the librarian is installed "pre or post" driver?
Should I uninstall the VG99 driver(could this conflict)?
I will attempt to install the driver on my netbook, but that's Win7, so it's not the same driver.
Any thoughts, or similar problems from anyone?
Thanks(-:

Determine if your XP Home OS has one of the service packs (SP1, SP2, SP3)

I think you may need at minimum SP2 version of XP.

Be sure, you have NOT connected the GR-55 via USB, until prompted to.

Service pack 3, and I turn unit on only when prompted.
But I do have the usb cable connected (with unit off) prior to prompt.
I'll do it again, without the cable connected, but should the GR be powered on, when I connect the usb cable? Or, connect cable when prompted, then power up?
Thanks.

I had a similar problem. If you have an older pc, like I do, a USB connection may not work.  Instead, I was able to use a USB connected midi interface.

Not technically a bug, but Roland claimed to have put all their synth knowledge into the GR-55, but they omitted the harmonizer and arpeggiator, which was available in the GR-33 and prior models.
Title: Re: GR55 Bugs
Post by: Witelite on February 07, 2011, 06:34:40 PM
I reported one to Roland as well. It seems like for PCM 1 tone you can change octave but if you try to do to PCM 2 and then go to save it , it doesn't save the changes. You can get around by changing pitch for pcm2 to +12 but it shouldn't work this way.

Woah! I knew about the lack of harmonizer, but no arpeggiator?! Not even on PCM sounds? I don't know how I missed this. I use mine all the time with my GR-33. This is a major bummer.  >:(

Hopefully there is an easy fix to this:
I edited a patch on the gr-55 to have only my NORMAL PICKUP on and with no effects.  (Turned off the PCM 1&2 and MODEL.)  I want to use this dry pickup only signal to my Axe-fx ultra.  It works fine until I try to save the patch to user 1-1.  When it saves, it is turning off the NORMAL PICKUP & turning on the MODEL.  Any idea why?

You may edit a USER Patch.

You may NOT Edit a factory Preset patch.

Be sure you are in the USER bank of patches, prior to editing.

I was editing a patch then saving it to the user bank.  Not sure what was going on.  I just went to a different patch, set it up exactly as the 1st one & it saved properly.  I then went to the original one & can't get it to save properly.  Not sure why, but I have a patch saved as I want.

The very same thing happened to me when setting up analog only pactes.
The problem was resolved because of a CTL pedal setting which switched off the analog input when saved, check your pedal and assign settings, as these may have been set from the patch you used as a template.

i'm not sure why it is being said that you can't edit the presets? i edited Stolling Rones in the rhythm 12-2 preset position and simply saved it to the user 1-1 position

you can edit the presets, you just can't write over them
Title: Re: GR55 Bugs
Post by: Guitarbot on February 13, 2011, 03:26:32 AM
sonnyv, I agree.  I knew my problem wasn't that simple.  I had already saved the preset to the user slot & then tried to edit & save, but it kept changing when I saved it.  I believe gumtown may have the answer.  I am at work & can't test right now.  I really appreciate the moderators & gumtown for all of their work.

The following looked like a bug, but it is not a bug !

AMP / TYPE / SWITCH = ON is not saved.
In one of my user patches, I tried to turn on AMP, ie. AMP / TYPE / SWITCH = ON, and then save it...
After save, or when I recall this patch AMP / TYPE / SWITCH is still OFF !
I also tried to save it in a different location, not solved.

In fact, I found this parameter was overwritten by a controller assignment (see Controller Assignments NOTE p.63)

Thanks ddlooping !

I hope Roland will release next firmware version with a small indicator after the default value of the parameter, saying this parameter is controlled. Because when you work with a lot of controllers is very tough to remember which parameter is controlled, especially if you start from old preset.

Witelite - I ran into this same problem last night, and wasted a lot of time trying to get to the bottom of it.  :(  Just before I shutdown for the night, I noticed that the patch I'd been editing had a CTL assignment pertaining to PCM2 Octave buried in slot 2 of the assignments screen.  I'd already applied your pitch detune workaround by this time, so I'm not 100% certain this explains the problem, but I'd put good money on it.

It definitely bears repeating:  if you're designing a patch from the ground up, begin by INITIALIZING.

I ran into something like it but for me it was the COSM MODEL ON/OFF parameter in the TONE tab. I just coudn't save
it as ON. But I was trying different things with the CTRL/EXP/EXP SW/etc. to figure out how to program them so god knows where the problem was. I got tired, I ditched the patch, went back to the original one and the problem was gone... :-*

I'm experiencing "saving" problems on the GR-55 as well. I usually have success saving my patches but occasionally they don't take. I am indeed in the User bank when I do this. For example, I can copy a steel string acoustic modeling patch to the User bank successfully. When I go in and change the new patch from steel acoustic to nylon acoustic, it will play as nylon and allow me to write it getting me back to the name screen but after saving, it reverts back to the steel acoustic setting. I double check to make sure I'm really in User and try the process again but no luck. The change will not take. So I try again changing another User patch to nylon acoustic and it might work fine. -Marty

P.S: one way to check the above, once you've saved the patch, is to press the CTRL pedal, use the EXP pedal and EXP switch to see if they switch on PCM2.

You can edit any patch you like, either User 1~297, Lead, Rhythm, or Other. But you can only write/save them in a User patch allocation (1~297).
When selecting any patch, it's contents are transferred to the GR-55's internal "temporary" memory location (the area of unsaved data which may have been modified), this memory is wiped when the GR-55 is powered 'off', and requires transferring/writing to a User patch memory location if you want the edited contents saved...

Title: Re: GR55 Bugs - Lock-up But patch still played...
Post by: FrankG on March 10, 2011, 06:12:49 AM
My GR-55 locked last night, in that it would play the patch it was on, but not advance to other patches, or styles ie; Lead, Rhythm, Other Etc... and none of the buttons like enter or edit were responsive, and would not shut down via the power button... To reset I had to pull the plug...

In all fairness I cycled the power switch quickly so the unit may have been staying "On" due to residual charge in the caps internally (but not likely)...

I was using a "User" patch that has been working fine and the problem has not resurfaced yet this A.M...

Post by: Gastric on March 10, 2011, 08:47:26 AM
There are sometimes, but not always, a 1-2 second rubbery ramping portamento type glitch when changing patches that use PCM.

I happen to be running in Bass Mode. I have not tried in Guitar Mode.

* Init two adjacent patches
* Set Patch 1 PCM1 tone = 275
* Set Patch 2 PCM1 tone = 276
* Play and switch from Patch 1 to Patch 2
* Note it takes about 1-2 seconds before Patch 2 starts sounding correct
* Play and switch back from Patch 2 to Patch 1, a similar issue does not exist

As best I can tell it's related to specific PCM tones, such as #276. It must take a while to initialize their performance or something. But it's an issue to be aware of.

Title: Re: GR55 Bugs - Lock-up on current patch - Update
Post by: FrankG on March 15, 2011, 07:15:16 AM
Per my previous Bug Post... the GR-55 has locked-up twice since posting...

I did verify that the Power switch was inoperative so it is not a true Make break switch but closer to and ATX power supply that is essentially always on.

So to re-cap the GR-55 is locked on the current voice, plays fine but can't be advanced to other voices and all input buttons are inoperable...

Possible cause... The GR-55 is still tied to a PC for config and patch back-up via the USB... The last time the unit locked, I went to check the PC to see if the Flr-Brd App could change the voices or access the GR-55...

With a blank-screen, I moved the mouse to "Wake-UP" the PC and instantly the GR-55 advanced the patches as I'd applied the buttons and dial wheel, and then powered off (I think  ::) because it happened pretty quick and it was late on Friday night)...

So it looks like when the PC goes in to suspend or power-save mode (whatever) it is the problem (VIA the USB connection)...

Will only know for sure once the GR-55 is stand alone from the PC...
Title: Re: GR55 Bugs
Post by: Elantric on March 15, 2011, 08:22:31 AM
What you describe is expected behavior. If your GR-55 is connected to a PC that has gone into power suspend mode, the USB port shuts down, and the GR-55 will sit there awaiting a USB handshake that never arrives,(essentially appearing to be "locked up") until the PC wakes up.

Having a patch writing issue..
On the 'Legato Solo' patch i cant seem to save a version with the Lp pickup set to rear..
it just keeps going back to the front setting  when i save/change to the patch..
is this a bug or user error ..has anyone else found this to be the case?
..any solutions welcome..

If you use one of the 'panning' pulsed patches and are not running stereo it wont be pulsed as the L Ch folls in the R Ch spaces. Fair enough really and not actually a 'bug' as such but....

Could not find a way around this other than using an assign and the wave pedal to turn the PCM tone on and off.
The GR-55 seems to struggle with faster BPMs though and you will struggle to get quavers at anything over 100BPM before it starts to 'miss' the Wave pedal transitions giving your 'pulsed' tone an odd rhythmic pattern to it.
Had a little more success by using the Wave pedal to change PCM volume which allowed me to push the BPM a little higher before the rhythmic patterning returned.
Anyone else confirm this 'effect?
Title: Re: GR55 Bugs
Post by: jwhitcomb3 on April 07, 2011, 10:14:38 AM
I think I may have discovered a GR-55 bug.

When I set the GK Vol to be the tone volume in the main controllers page (not the assigns page), setting only the modeling volume to "on", and then turn the GK volume knob down, the model gets quieter. So far so good. But then, with the GK knob still down, if I push the EXP switch, the model volume pops back up to maximum, even while the GK knob is turned down.

This happens regardless whether the EXP or CTL or any assigns are programmed or enabled. Doesn't seem to matter what controller the EXP switch is set to either.

Anyone else run into this?
Title: Re: GR55 Bugs
Post by: mbenigni on April 07, 2011, 11:59:26 AM
Quotethe model volume pops back up to maximum, even while the GK knob is turned down.

I've had some variation of this problem, for sure.  I wasn't using the EXP switch at all, but I've had a couple of cases where the GK Volume (set to function exactly as you describe) just basically stops working, with the modeling tone sending at full volume.  In these cases I've basically scratched my head (maybe cursed once or twice depending on how late into the evening...) and switched patches back and forth, and then the problem mysteriously goes away.

Like every other "problem" I've had though, I never manage to duplicate them/isolate them precisely enough to rule out user error.  There's always so much going on at the same time with the GR-55, it's difficult to keep your wits about you.  :)

Anyone had problems with the sound from one string failing after time.
I've had this happen about a dozen times.
Rebooting the gr55 solves the problem.
Could this be the 13 pin chord.

I think I may have discovered a GR-55 bug.

When I set the GK Vol to be the tone volume in the main controllers page (not the assigns page), setting only the modeling volume to "on", and then turn the GK volume knob down, the model gets quieter. So far so good. But then, with the GK knob still down, if I push the EXP switch, the model volume pops back up to maximum, even while the GK knob is turned down.

This happens regardless whether the EXP or CTL or any assigns are programmed or enabled. Doesn't seem to matter what controller the EXP switch is set to either.

Anyone else run into this?
I think I've narrowed the scope of this bug.

The "tone volume" controller parameter allows you to set any of four sources to "on" or "off": PCM#1, PCM#1, model, or pickup.

If you set mutually exclusive sets of these sources to "on" and assign them to different controllers, they will still conflict. For example, if you set the GK volume to control the model tone volume (off, off, on, off), and you set the EXP to control the PCM#1 and PCM#2 tone volume (on, on, off, off), the model volume will still pop back up to full when you step on the EXPSW.

You'd think that setting a source to "off" for a controller assigned to the tone volume would cause that controller to ignore the source set to "off."

The work-around is to only use the "tone volume" target in one of the Pedal/controller parameters, and set up any others in the "assign" area, where there does not appear to be a conflict.

Thanks, Jonathan.  That's probably what was tripping me up as well.  Weird behavior!  I've gone over to using system-wide settings for the exp pedal and GK controls (with pretty much exactly what you describe, except no dependency on the Exp pedal switch) in order to simplify patch programming.

It first time when my GR55 freeze. I use AcComp/BassSplit patch (by Ian) and was noticed that the sound of the low E and A (modeling gitar, -12 alt. tuning) some times is terrible. It was some kind of self oscillation, vibration. I try check settings on the GR55 but in this moment it wasn't react. I coun'd event power it off.

But... I had connected the GR55 to my MacBook with running Gumtown editor.  Mac was closed so it was theoretically sleeping... but when I disconnected it GR came back to the life.

If you connect the GR-55 via USB to a "sleeping" MacBook - Yes, the GR-55 WILL lockup. This is Normal.

Its part of the new "Green" electronics initiative which dictates that any peripherals connected to a sleeping computer must go into a "suspend / power save" mode, to conserve energy.

Avoid this by changing your MacBook's System settings  - disable "sleep mode" when you want to create music with the GR-55.

Not so much of a bug as a progress report on a problem i've been having regarding the 'pulsating' and 'beat & groove' PCM's. Since i got the GR-55 i've had occasions where the unit just makes a drone when using any pcm that is tempo based. It happened again today (backup settings & factory reset. Again!!!) and following some reading on this forum, it hit me.

One of the threads was discussing 'tap tempo' and how it is not available when midi sync is enabled. Doh! That was it! These PCM's rely on a tempo and unless you have your unit synced at the time. You'll just not get owt!

No problem with the unit or the firmware, problem with the user!

On another note... I was not getting any sound from the unit apart from the guitar out. Scratched head!, factory reset, scratched head some more...

Expression pedal heel end down, minimum value. Doh X 2

Anyway I'm off to factory reset myself.

I don't know exactly how I did it, I was playing with some alternate tunings and  some 'user' tunings on the COSM guitars. After a while I went to tune my guitar (in individual string tune mode, I love that !!! ) and somehow all the strings were wrong ( Low E showed as A, A as a D etc. ). I tried disabling alt tunings, also setting the intervals back to zero, but it would'nt come back to normal until I did a factory reset.
I reloaded my custom patches and the tuner still worked

Does Abelton support ASIO driver use? If it does, I recommend using ASIO mode as that provides minimal latency.
If you are using the GR-55 as the output audio device (since ASIO spec only allows one audio device at one time), then use "direct monitor" setting in the GR-55 instead, as the signal will be double buffered to send to the PC processed then sent back to the GR-55.

 hope Roland will release next firmware version with a small indicator after the default value of the parameter, saying this parameter is controlled. Because when you work with a lot of controllers is very tough to remember which parameter is controlled, especially if you start from old preset.

There are sometimes, but not always, a 1-2 second rubbery ramping portamento type glitch when changing patches that use PCM.

I happen to be running in Bass Mode. I have not tried in Guitar Mode.

* Init two adjacent patches
* Set Patch 1 PCM1 tone = 275
* Set Patch 2 PCM1 tone = 276
* Play and switch from Patch 1 to Patch 2
* Note it takes about 1-2 seconds before Patch 2 starts sounding correct
* Play and switch back from Patch 2 to Patch 1, a similar issue does not exist

As best I can tell it's related to specific PCM tones, such as #276. It must take a while to initialize their performance or something. But it's an issue to be aware of.

If you use one of the 'panning' pulsed patches and are not running stereo it wont be pulsed as the L Ch folls in the R Ch spaces. Fair enough really and not actually a 'bug' as such but....

Could not find a way around this other than using an assign and the wave pedal to turn the PCM tone on and off.
The GR-55 seems to struggle with faster BPMs though and you will struggle to get quavers at anything over 100BPM before it starts to 'miss' the Wave pedal transitions giving your 'pulsed' tone an odd rhythmic pattern to it.
Had a little more success by using the Wave pedal to change PCM volume which allowed me to push the BPM a little higher before the rhythmic patterning returned.

Restore the COSM PU selection via GK-3's "S1" (up) & "S2" (down) to navigate all 5 COSM model pickup choices in the Strat COSM Guitar models.
In essence clone the VG-99  COSM pickup control selection method for "S1" & "S2"
It would also be great if they added a pickup position indicator to the top level screen. Not necesarilly a graphic, even text along the lines of F, F+M, M, M+R, R would suffice - just something so you can tell without going into a menu.

Making the list of Assign targets more comprehensive would go a long way toward improving the GR55.  In addition to Hold, I would like to see Pitch Bend added - seems like a no-brainer.  There are others, I'm sure.  I'll be back to edit this post as they come to me.

I'd also love to see an option for repurposing the "Lead/Rhythm/Other" and/or "V-Link" buttons, to use them as Assign sources, or to turn the Tuner and Phrase Loop on and off without risking a patch change.  (Those 2-pedal combos are absolutely terrible IMO.)

It would be quite nice if Roland would publish a bug list, too. It would save users a lot of frustration. I work in tech pubs for a very large router company and we do that. We publish "release notes" for each software release that includes new features and a list of "known issues", aka bugs. It's a very common process in software development.

If you speak with Roland reps, you might ask about their release notes too. Their software developers keep them, why not publish a list of bugs Roland knows of that affect users? We might be able to help them by providing work arounds, testing, corrections, etc.

A few weeks ago, my Gr55 was  in a situation whereupon receiving a patch change from a Ground Control Midiboard its sound became completely muted. The only way to get the output sound back on, was pushing down on the GR55 pedals toe switch. This seemed to be the case with every patch I tried. -So basically every time I tried to change patch, it would just mute the unit 'til I went over to it and stomped on the toe switch.  Powering down the GR55 and back on again made no difference, it just stayed like that all day. The next day however everything was back to normal and it was fine again.
  Until a couple of days ago however, when exactly the same thing happened again. On neither occasion were there any different circumstances in the way the GR55 was set up to usual, or what other things it was connected to. I always send it patches from the Ground Control midiboard. So I can't see anything that might have triggered it to have behaved differently from all the other times I switch it on.

- Anybody got any suggestions as to what might have been causing this problem?

Please, include an intelligent HARMONIZER, as on previous models
Title: Hardware Bug - GK-3 screw loose
Post by: hanzarouth on May 23, 2012, 09:10:24 PM
I've been using my GR-55 with GK-3 pickup for quite a while now, and today I noticed some exposed wires from the top of the pickup. The screw that keeps the little cap in place had fallen off. A tiny screw like that would normally be hard to find, but if you'll notice in the pic, the pickup magnet held onto it. I recommend you check this screw regularly to ensure it is tight. There should probably be a locking washer or something.

Great thread! Nice to know about these problems before I may encounter them on my new GR-55

Have owned GR500  GR300  GR700  GM70  GR30  GR33

Wow! You sure have owned a lot! I have my GR-30 as a backup to my new GR-55. Elantric said that certain members still prefer the GR-30 to the GR-55 in certain ways. I think he said for tracking reasons. I sure would like someone to elaborate upon that. I'll try doing a search to see if someone has already commented about this.

UPDATE:

I did an advanced search and found it difficult to know what link to click on to find my answer about why some people prefer the GR-30 to the GR-55

Perhaps it's the GR-30's arpegiator. The GR-55 does not have one.

It's my understanding that the GR-30 arpeggiator is actually programmable, which makes it even more useful than the arpeggiator in the GR-33.

Be sure to get the GR-30 Editor

It needs Windows, and was written back in the Win98 era

(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Fi412.photobucket.com%2Falbums%2Fpp208%2Felantric%2Fgr-30-edit_screens.png&hash=f4c616559e0a3a9c1c863881eb9d89fda41377eb)



When I show most GR-30 users those Control Edit screens above, most never knew the the GR-30 was capable of such things. Its the GR-30 Arpeggiator (MIDI  Clock sync-able) and separate string MIDI assignments with a good amount of MIDI controls per string that keeps the GR-30 in use even today  - Robert Fripp still uses it.  The GR-55's Guitar to MIDI Implementation pales by comparison.

But Roland is famous for having buried easter egg features - that only become enabled once you read the manual , and do a magic handshake or "press this button while powering on the unit"

This is why I was furious when Roland announced there would be no official GR-55 Editor

I told them without an editor, after an initial brief period of initial release sales, they would then decline and stagnate  as most GR-55 users would be lost and give up after 6 months and sell it on ebay.

In my mind, Roland owes Gumtown far more than a free GT-100 for his time creating and supporting the GR-55 Floorboard Editor.
Who on earth programs the GR-55 without Gumtown's Editor?

Might as well use a Dymo Labler to write your biography.

there is a bug that causes the ctl pedal to intrermitantly do the opposite of some assignments or mix and max which assignments it will do at a given moment. i have had endless discussion to try and figure it out and have determined it is a bug not a conflict or error. thanks

 Here is a copy of recent bug i have found that i sent to Roland, they say they are working on it

Hi Oliver , i updated the unit to 1.50 as soon as it was available.

I had a look on the V forum last night and there are a couple of people who mention that polarities have some times reversed when they return to certain patches , it also seems that a couple of users say the patch does not sound the same ,like as if an asignment has changed

What is strange  is some patches do not alter the polarity of the affected patch when you return to it , but some do.

Its a difficult problem, its as if the assign hold in system even  when turned off is allowing some corruptable data to infiltrate the affected patch and in this particular ,case reversing the polarity of the assignment .

To get around the problem i go to a patch that i know doesnt affect the assignments , i then return to the affected patch and its back to normal , its only some patches that corrupt it .

If its a bug its a major one as it would explain some not so experienced users saying ' it doesnt sound right' when i come back to the patch .

The only other thing is that my unit may be  faulty , it has been returned once for a faulty edit switch a couple of weeks ago

       Cheers Clinton

All -


Have any of  you seen a post regarding the 55 freezing?  Specifically, the unit is on, continues to output from whatever patch is loaded, but no longer responds to any of the buttons.  Can't turn the unit off - has to be unplugged.  When you plug back in, it may repeat, or, it may be Ok.

Any thoughts?

Thanks!

Danno

I suggest  -
Save your patches and do a factory reset

Be sure you have updated the GR-55 firmware to latest version 1.50

Realize that the GR-55 is designed to enter a power save  "freeze" mode - but only if left on after 40 hours. Its part of the global "green" initiative laws in many countries.


best of luck

When I set the GK Vol to be the tone volume in the main controllers page (not the assigns page), setting only the modeling volume to "on", and then turn the GK volume knob down, the model gets quieter. So far so good. But then, with the GK knob still down, if I push the EXP switch, the model volume pops back up to maximum, even while the GK knob is turned down.

This happens regardless whether the EXP or CTL or any assigns are programmed or enabled. Doesn't seem to matter what controller the EXP switch is set to either.

==
I think I've narrowed the scope of this bug.

The "tone volume" controller parameter allows you to set any of four sources to "on" or "off": PCM#1, PCM#1, model, or pickup.

If you set mutually exclusive sets of these sources to "on" and assign them to different controllers, they will still conflict. For example, if you set the GK volume to control the model tone volume (off, off, on, off), and you set the EXP to control the PCM#1 and PCM#2 tone volume (on, on, off, off), the model volume will still pop back up to full when you step on the EXPSW.

You'd think that setting a source to "off" for a controller assigned to the tone volume would cause that controller to ignore the source set to "off."

The work-around is to only use the "tone volume" target in one of the Pedal/controller parameters, and set up any others in the "assign" area, where there does not appear to be a conflict.

This bug is becoming a real issue for me. I am going to have to try using an FC-200 with the GR-55 to do what I want to do.

Many of my patches have a modeled acoustic guitar sound with the volume control on the GK pickup setup to control the volume of the modeled acoustic guitar. Then, I have 1 or 2 PCM sounds with the expression pedal setup as the volume control for those. Then, I assign the expression switch to control the rotary speaker brake or an octave up switch, etc. If the acoustic guitar volume is down on the GK & I activate the expression switch, the acoustic guitar comes back on at full volume.

Hello everyone,

recently a problem with grooves patches appeared in my GR 55... that sounds like in a file in attachment... With all grooves patches (in the recording the patch number 833 was used)... I just installed GR-55 System Update v1.50, but the problem is not solved. Does someone met those previously and what should be done to be corrected?

Best regards,
Andreja

Hello everyone,

it's me again... I did the factory reset and now everything seams to be fine. But I'm still wondering what has caused the problem...

All the best,
Andreja

Post by: shawnb on February 04, 2014, 12:45:46 PM

The grooves patches, IIRC, need a tempo within a certain range & need an explicit tempo.  You can get similar oddities if you tell the GR55 to follow an external tempo, but don't supply said external tempo. 

One possible explanation.  I thought I'd broken my '55 when it happened to me...

Thank you Shawn very much! Yes, that's it... I've been doing something with the sync with Cubase...as far as I remember... I was thinking about the service, too... :) Here how it sounds when everything is OK..

All the best and thank you,

Sorry for coming in late on this, but it sure would be nice to be able assign a manual pitch bend range. Not every external gadget works at a range of 24.
