I want to use an ENGL Z-15 footswitch with a Laney GH50L and a TC G-Sharp.

Can i use the Z-15 to change channels on the laney using the switch loops, and also have midi programs from the g-sharp saved into different patches?
Im not very experienced in MIDI and stuff, so any help is appreciated!

The GH50L is single channel amp with a boost so I'm not sure why you want this :P you do know you can buy Laney footswitches to activate the boost?

Its the VH100R that has multiple channels

no i dont think I explained it well. I want to switch the boost on and off, and have different effects for different tones and parts of songs, etc. and have different tones in different patches.
