Sooooo, I have some files from my SNES MIDI Remaster Project I'm working on. I just realized that the timpani in the game is -7 semitones from the timpani in all of my generated MIDI files. Re-exporting all of the files as MIDI is a giant pain (I'd have to re-do up to 13 of them, some of which I've already just redone because I made them too short before I finalized my "production process"), and very time consuming. Is there an easy way (in Windows) to change the pitch of a single instrument? I have several editors, and I know I can change the pitch of a whole channel in some of them, but most of my files will have multiple instruments on each channel, so others besides timpani would get modified.
