Setting up G Major to control volume via Midi

[Tremonti]

How do I set up the G Major to control volume via midi. I have a Ernie Ball mono pedal and I know I can plug it into the Ground Control to do this. Question: How do I do this and keep the Triaxis from getting involved(not have the pedal change values on Triaxis)? Im using the ISP Decimator and with the volume pedal in the audio chain right now it doesnt allow for a good sound reduction via the volume pedal because it cuts the signal off. The ISP works great but would like to use the G Major to lower the volume because it isafter the ISP and therefore wouldnt effect the ISP's signal and cause a cut off. Anyone???

just use different midi channel for volume then what you use for the tri...easy!!
