Don’t know if this might help anyone but it works pretty well for me. My “BandHelper” program is sending MIDI commands one at a time to change my lights scene per song/section, and I wanted a way to quickly ‘release’ any button that remained active before I go into the next song. I know Photon is working on a plan to do this with button types - In the meantime,
I just used Reaper to create a MIDI track that does nothing but Release my buttons very quickly. So now before I start my song, I do the quick “play Midi File”, then on to set up the next song. Easy…
