My Helix controls an H9. I want one switch to change the H9 to preset 1, another switch to change to preset 2, and if neither is on, I'd like EITHER (1) the H9 to be bypassed or preferably (2) the Helix effects loop that the H9 is IN to be bypassed.
Maybe this is because I don't understand MIDI very well, but I know I could just have the Helix's loop permanently on and send the BYPASS command to the H9, but I don't see how to have a single switch send multiple MIDI commands (namely, the PC command to change to [e.g.] preset 1, the command to UN-bypass the H9, and [upon turning the switch to the off position] the command to bypass the H9).
Alternatively, if I could just get two different Helix switches to turn the Helix effects loop on/off (that is, 2 switches controlling the same exact effect in the signal chain), then I'd be set. But I don't think the Helix can do that.
I'd love some help with this!
