I have a MIDI file where channel 11 was used for a snare drum part when it was created on the SC-88 hardware many years ago. I would like to change its channel from 11 to 10 (the normal drum channel for GS MIDI).  Other than individually editing each and every note, is there a way to mass modify a MIDI channel?

If the data is displayed with one channel per track, the MIDI channel in the track header will override the channel data in the notes. To actually change the channel assignment in the note data, set the channel in the track header, select the track and "Bounce to Clip(s)."

Perfect! Thanks!
