Summary: mrpeach/midifile works best with real note-off messages

Initial Comment:
Some software (at least timidity and midi2ly) require real note off messages and not the "note on with velocity 0" messages provided by [makenote] used in the midifile help patch.

I'm not sure what the official spec says, but switching to writing proper note-off messages to the file fixed my issues with notes not ending and instrument polyphony being exceeded.

So, instead of

[makenote 64 100]
[pack f f]
[list prepend ...]

Use:

"my note float"
[t f f]
 |    [pack f 64]
 |    [list prepend ...] // channel number + 144
 |
[pipe f 100]
[pack f 64]
[list prepend ...] // channel number + 128

or similar.
