Drum pads assignments not working after relaunch
Mainstage 3, ver. 3.4. M-Audio Oxygen49.
After assigning drum pads to play MIDI notes in an Ultrabeat sampler and relaunching, the assignment still shows as valid, but doesn't play the sound. I can fix it by deleting the channel strip, then starting from scratch with new assignments. I made this video to show the problem.
