I bought a MIDI cable today, plugged in my Whammy into my Helix LT (with both MIDI and through the FX-loop), set the MIDI CC accodingly to the Whammy 5 manual, but I can't get it to work. I made a test footswitch with FS9 to switch the whammy into Haromny + OCT up (CC 63, Value 127), but it doesn't do anything. Changing from MIDI in to MIDI thru on the Helix didn't help either.
