[PATCH v4 0/4] MR5141: dmime: bandtrack for MIDI files

[Yuxuan Shui (＠yshui)]

Create a bandtrack for MIDI files by picking out the MIDI 0xCn events, and creating matching DMUS_PATCH_PMSG.

This also has a commit adding a stub chordtrack, which is small so I think a separate MR is unwarranted. Can be split out if necessary.
