MIDI
On Helix, the CC numbers are fixed
The CCs above are reserved for global functions and cannot be learned as controllers. If you try, the modeler puts up a dialog saying so. If a MIDI controller set up for another brand does nothing here, check its CC numbers. They may collide with the reserved list, or be numbers Helix does not listen to.
Helix 3.80 Owner's ManualCC#32 picks the setlist, a Program Change picks the preset within it, and CC#69 picks the snapshot. The Setlist menu prints the exact three values for whatever is selected.

Helix 3.80 Owner's ManualSend the snapshot straight after the preset
A CC#69 snapshot change sent during a preset load is buffered and applied once the load finishes. Send a Program Change immediately followed by CC#69 and you land on a preset with a different snapshot than the one it was saved with. Use it to build a setlist where one preset serves several songs.
