Mark IV Channel Switching Via MIDI Board

[NickSleeper]

Alright so......
Theres three switches for each corresponding channel on the back of the amp. However, most Midi floor boards only have two External Footswitching Jacks. Is there a way to use all three channels within the switching capabilities without having to buy another midi pedal / another switch? If I plugged a shorted cable into RHY1, and connected RHY2 and LEAD to my board, and turned both External switches off on the board, would RHY1 come on?

Any thoughts?

TRY IT!!!!

I am not sure if one channel has dominance over others but if it does you might be in luck.

yep, i'm pretty sure it works that way. when i tried the mark IV i connected a switch of my fcb1010 to the lead switch when the amp was in channel 1. as i pressed relay on and off, the amp switched between those two channels. so yes, you only need two relays to switch 3 channels in the mark. don't forget however that it was nice to have a third relay to control de GEQ...
