yes I agree there. But in the meantime I figured out how to rewire the EV5

My problem with the LED has been that the state is invalid when you switch patch. Example: in patch #5 you turn on echo and the LED (and echo) is ON. Then you change patch to #6 and the darn LED is still on without the effect associated to it is on. That is confusing.

Hi CodeSmart

Using the GP10 live for the first time I had a lot of confusion with the same FS6 issue.
It was great to find it was possible to have the FS6 leds indicate state in momentary mode, but when moving patch the flippin things stay lit...grrr!
Did you find a solution?

Nop, I don't think there is a solution. The latch circuit in the footswitch can't know that you changed patch and can't know the actual state of the GP-10 / GR-55.

A better footswitch and Roland synth would use bi-directional communication allowing the external footswitch latch to be reset or set by the synth unit to the actual state of the feature controlled.
Got more gear than I need...and I like it!

Yes, that seems to be the way of it.
I've gigged the GP10 a few times now, am starting to get the hang of remembering to quickly tap the lit switches after a patch change, or tap twice to re-engage in the new patch.

It is a wee bit frustrating Roland hobbled it somewhat, but I'm grateful such a device exists and for such a low price considering what you get.
Despite it's compact size, it wouldn't need more than a handful of modifications, to make it's live use much much simpler.

Roll on the GP10 MkII :)

i have an ev7 expression pedal which i want to use to control the wah on the gt100. i can't seem to get it to work right. the tone seems to go all over the place as i press the pedal then when i release it the tone doesn't go back to normal. is my setup wrong on the pedal or how do i set it up?

Post the problem patch - so others may test and debug

But the conventional method for Wah on GT-100 is use the GT-100's onboard Expression pedal using its built in Expression Toe Switch - which is already mapped to Wah for most GT-100 patches

got the expression pedal all figured out. if the value of the pedal is 0 the pedal remains off. as soon as i press the pedal to increase the value to 1 the pedal turns on and it sends the value to the wah effect. works perfect.

The ex-50 looks great, but $129 is pretty pricey...
Footprint reminds me of my old DOD fx-17 - i would like to say that a used one of these would be a good candidate but I have a sneaking suspicion that it wont work as a control pedal. Hmm, i should check this.

Its working great as an expression pedal. You do need to order it with the right value pot in it, though.  They have a 50K and a 10K

What is the cheapest expression pedal I could use on Boss GP-10?

Would Behringer FCV100 or M-Audio EX-P works?

Does the FCV100 get the full range?
Do I need the polarity switch on the M-Audio EX-P?

By the way, I also intend to use this expression on Peavey Nano Vypyr Amp.

Which one would likely works with both?

M-Audio EX-P:


Behringer FCV100


GP-10:


Nano Vypyr:

The M-Audio EX-P does include a switch on the bottom that is supposed to make it "Roland Compatible"  - but many complain the M-Audio EX-P's 12K Pot  does not offer the full sweep of a genuine Roland EV-5 Expression pedal.


FWIW - a Roland EV-5 Expression pedal is a 10 K Linear POT

Behringer FCV100?

The Behringer FCV100 is not compatible with any Roland / Boss Expression pedal Inputs.

Behringer FCV100 is a VCA Stereo Volume pedal with a switch to place it in Control Voltage Output Mode, and near impossible to locate its Internal battery compartment - it makes a great pedal for a miniMoog Control Voltage input -or use it as an IQ Tester, next time you audition a keyboard player - hand him a Behringer FCV100 and ask him to change the battery inside the Behringer FCV100 under a minute.

Is the M-Audio EX-P also using 10K pot?
Does it function just like the EV-5?

Roland EV-5 is $60
M-Audio EX-P is $30

Where can I get cheap Roland EV-5?

The peavey customer support also recommend the Roland EV-5 for their amp.

I think any volume pedal will work. Connect it with TRS to 2 mono Y cable.

Read the Expression pedal thread

Expression Pedal Options
http://www.vguitarforums.com/smf/index.php?topic=33.0

Many Roland /Boss users trying to use the M-Audio EXP-1 found they had to swap out the 12k pot for a 10K linear pot. This is because only a 10k linear pot delivers full sweep of the intended control assignment.

I have Yamaha expression pedal (50k Ohm) and GP-10, it works. I don't know Peavey, but expression pedal is just a voltage divider needed by GP-10 to know your foot position. So 10k or 12k should no different, If you need certain control/feel of your foot maybe you can choose expression pedal curve setting in the Boss GP-10.

This is the reply from the amp's manufacturer:

The NanoVypyr will work with an expression pedal which takes the place of the morph knob on the effects.  It is designed to work with a passive volume pedal, but Peavey doesn't actually offer this.

Here are some comments from the designer as to what products that may be used.
 
It needs to be a low-Z volume pedal, and it needs to have a TRS jack, which is something they often add to stereo low Z volume pedals for use as an expression pedal.  The nano is designed to accept a standard expression pedal connection, so it's not unusual or anything.
 
Here are two examples:
 
http://www.musiciansfriend.com/amplifiers-effects/roland-ev-5-expression-pedal
 
 
http://www.musiciansfriend.com/amplifiers-effects/rocktron-hex-expression-volume-pedal
 
 
For modding a pedal someone already has:
 
1.  Use a TRS jack
2.  Use either a linear (B-taper) 10K or 25K pot
3.  Wire ground to the jack sleeve like normal
4.  Wire the high side of the pot to the jack ring terminal
5.  Wire the pot wiper to the jack tip terminal
6.  Low side of the pot goes to ground

For those of you looking for a physically small sized control/expression option:  I just purchased the

Hotone Soul Press Volume/Wah/Control pedal.
http://www.hotoneaudio.com/products/press/Volume_Expression_Wah_Wah_Pedal/75.html


 I can report that it seems to have a 10K pot in it and works very well connected to the Control Input of the VG-99. 
This pedal features a very compact size, metal construction, and feels generally very sturdy. 
It has 3 modes:  Volume, Wah, and Expression.  In Volume and Wah mode the unit requires power. In Expression mode you can connect a TRS cable to the input side of the pedal and the unit functions as a control pedal. 

Since it has a Wah function, it has a switch at the Toe position.  If you engage this switch while in the Expression mode, the expression signal goes to 0.  I've easily set up the VG-99 to turn on/off the Wah using that switch....

And, you can use it as a wah or standard volume pedal when not using it as a control pedal. 

Recommended.

I've got one of those Soul Press pedals as well.  Pairs nicely with a Blueboard if you want to add an expression pedal without sacrificing portability.

I have a Moog EXP pedal, and it does not work well with Boss EXP input,
it is designed for C.V. with a 100k ohm main pot and a 50k low limit trim pot.
It will be just a simple procedure of swapping the 100k pot for a 10k one though.

I just received the M-Audio EX-P today.
Please take note:
It works with the GP-10 using the "M-Audio" Mode and not the "Other" Mode

Same with the Amp.

The "Other" mode seems to only have 2 steps. On and Off.
While only the "M-Audio" Mode has the swelling effect.
