* Song type is now removed: Testing... first commit, more likely to come. (Tim)
Midi import tested seems OK so far with GM, GS, and XG files.
TODO: Exporting song type sysex - use instrument init list instead? Or store with parts? (Nah!)
Or if all ports used in song are GM, GS, or XG, use those instead?
What about mixed? Try to use 'switch port' meta event to help?
TODO: Instrument init sequences. Need some kind of editor. Need timing mechanism while in 'stop' mode.
Was thinking these events should be in FRAMES or real time - not affected by tempo. Jack slow sync
callback might help. (Also try to re-enable metronome precount - similar concept here!)
TODO: Verify patches popup/boxes display for proper operation. And everything else, bugs, CLEANUP etc...
