Thank you Silverhead.
i already read about the Snapshots. My Problem with them is, that my midi controller just sending singnals from 000 to 127. Depending on my choosen setlist, midi signal 000 ist loading preset 000, signal 001 is loading preset 001. I think my midi-device uses Midi Base channel 0. I hat to put the settings on OMNi in my Helix (GLOBAL SETTINGS --> MIDI/TEMPO --> MIDI Base Channel: Omni). With this setting my Helix reacts.
Can i say, that Preset 000, Snapshot 2 shall react on signal 20 (for example) ??
Best Regards.
