I'm looking into putting together a "no expense spared" pedal board, well, mostly no expense spared. I'm thinking of getting a Pedal Pad board and using a Boss ES-8. The Pedal Pad has an option to build in a MIDI connector. I'm trying to determine how many MIDI connectors I would need built into the Pedal Pad. I've never used MIDI before so I just want to double check my thinking. To use the ES-8 to control channel switching and solo boost in this arrangement I'll just need to run a MIDI cable from the switcher to the "inside" MIDI connector of the board and then run a MIDI cable from the "outside" MIDI connector of the board to the MIDI IN on the amp, correct? No need to connect anything to the MIDI out/thru of the amp?
