How to control amps with analog relay footswitches for channel switching
Some amps use MIDI, but many amps use analog footswitches to switch between channels (i.e. Clean and Crunch) or to turn reverb on and off.
If your amp uses standard TRS footswitches (either latching or momentary), then they can be controlled directly using the MC6 Pro's relay ports (see: How to use the Relay Port ). For our older products, like the MC3/MC6/MC8, you'll need to purchase a 3rd party MIDI to relay converter that can read the MIDI from our controller and convert that into a relay message for the amp. Some examples include:
Midi Solutions Relay ( https://midisolutions.com/prodrel.htm )
Voodoo Lab Control Switcher ( https://voodoolab.com/product/control-switcher/ )
Pirate Midi CLICK ( https://piratemidi.com/products/click-midi-interface-relay-switcher ) - discontinued, but available
We used to make one as well, but it is not currently in stock ( [https://www.morningstar.io/relay-interface]() ).
NOTE: Some amps use special footswitches and thus can't be controlled this way.
