Even if you don’t have (or can’t find) an FC7, it’s not too difficult to make an adapter with the FC7 DIN plug at one end and some 1/4” female inputs at the other and just plug in a dual tablet type footswitch to do Perf. Up/Down hands free if you need it.

I also really like having the Leslie Fast/slow and on/off on foot switches when trying to do the full B3 thing. Sadly, FC7 assignments are global, not per Performance, it would be awesome to have them vary as needed!
