Midi support when in Helix Native Posted April 7, 2018 Not Reaper, but for those using Ableton - there's another way to do it, which I've just learned yesterday, you have to "group" the track with HN and map it's chain to a macro virtual knob. Then you can map this knob to range of notes - this way I could map the 8 pads on iRig Keys I/O to be my snapshot buttons. Works like a charm. Just need to make sure pads are using different midi channel than keys and don't interfere with each other. I can now switch instantly between snapshots just by tapping the corresponding pad.
