Well. No. Values from 0-63 are the release of the switch and 64-127 the press of the switch. Although it doesn't seem to make any difference, whatever value goes it just toggles the switch (just like you were just stomped on it)
@Ed_Saxman: I don't quite understand, what you try to suggest, so I obviously didn't explain clearly enough what I want to do: Basically, I want to control the Helix solely via MIDI Commands. I want to put it on stage and never ever want to have to touch it. (I just want it infront of me in case something happens to the live player, so it doesn't receive any MIDI signals anymore). So all I might want is to use the MIDI through, if there is another guitar player, that also wants to switch her board via MIDI. So far, it works quite nice (even though there is some latency when switching Presets, but I usually only change the blocks in the effect chain via the FSBs in a song). To make sure, the preset is in its standard condition (regarding the footswitches), I simply change to any preset and then back to the one I want during preclick.
