SP-16 Midi configuration bug

If you assign a track to a midi channel that is not the same as the track number, the SP-16 will seemingly randomly change the midi channel back to the track number once the project is saved and reloaded.

For instance, change track 4 to a midi track and assign it midi channel 16. Now make track 16 a midi track and assign it midi channel 4. Save, and reload. Either one or both will be set back to the default midi channel.
