Simple SEQ or MIDI editor

[ughman]

This should support some batch actions such as:

• Shifting all notes on a channel or program by some amount
• Correcting the 100%/127% volume issue
• Batch program change number replacement

This should make it easier to just jam in external midis and try them out, although playback would help with that as well.

Needs issue #15

Will the SEQ/MIDI player use the NSF's soundfont or will that be a seperate thing?

[ughman]

That's the intent. If I can't get it working well, and I probably can't because I suck at this music stuff, I might be able to rig http://github.com/ughman/c2c to play back SEQ's with the same code the game engine uses, so it should sound nearly identical. That's basically how PSF soundtrack rips work anyway.

• Also should support editing SEQ loop points, which aren't standardized (AFAIK) in MIDI but are in SEQ.

Loop start is NRPN MSB with value @ 20 followed by a Data MSB w/ value 127 in the tick after the NRPN. Loop end is NRPN MSB @ 30 for those who don't know (do these work with Crash 1?). Also I had just seen C2C an hour ago, awesome work.
