I just bought an M-Audio Keystation 88ES. I have a used Behringer expression pedal. The pedal works fine in the sustain input, but when I insert the jack in the volume input it cuts all power to the unit. When I pull it out, power comes back on. Is this a fault with the keyboard volume input, or with the pedal, or do I need to configure something? Thanks.

It has a limited voice generation capability. There are L and R audio outputs on the back... Just don't expect every fancy synth voice to be in it...

The FV300l WILL NOT work tying it into the EXP of the BSY600. What you need to do is to run your guitar into the IN of the BSY600 and use TWO audio cables from the BSY600 output, the OUT and the DIR out and run those into the two IN's of the FV-300L. Then use whichever function by connecting the two OUT''s of the FV-300L to two channels of the mixer or a two channel amp so you could proportion the BSY600's effects as desired. You could also just use whichever out from the FV-300L you want which originates in the BSY600. The BSY600 is made to use an expression pedal that is a single TRS plug which is simpler, but you can use your FV-300L as I have described just as well, it just can't use the EXP input of the BSY600.

First step is to download Midi Monitor http://www.snoize.com/MIDIMonitor/
just to make sure you're actually getting midi over USB into the computer. This is a great utility that I use all the time for troubleshooting midi data issues.

I have Behringer Fcb 10 10,but i want to know how expression pedal volume work when connect with GR55.

If the traces are lifted, then use jumpers to the points of origin of each trace. Tack the jumpers down with silicone seal or other adhesive.

Replace the connector ifthere is any chance of damage to the connector itself.

Most of these use conductive rubber pills that are pressed onto circuit board traces by the keys.

Clean the board AND the pills with 99% isoprophyl alcohol and QTips.

I have two of these. First thing check your power adapter for output. Just because LED's are on doesn't mean there is correct voltage... There is no reset button... Cycling power serves to reset it.

ALSO check the power input connector... sometimes those get intermittent and break connection due to vibration and initial current surge when turning on.

You have to install software to connect the device to the General MIDI input. This rquires a driver for the 88ES.

You can buy new connector and replace broken one. You need skill at soldering and of course have to open the unit to access the broken connector.
