Re: Exporting quarter tones to midi?

Thanks David!

I guess my question then is whether there's a way to export it to another notation program - since all of them use a different protocol to define quarter tones. I saw that there's a lilypond->musicxml project but I am not sure what stage of development it is in. 

Many thanks,
Avner

Uh, just do it?


produces


here.  Which sounds just like I'd expect.

lilymidi --pretty outputs
Filename:     quart.midi
MIDI format:  1 (one or more simultaneous tracks)
Divisions:    1536 per whole note
#Tracks:      2

Track 1:
    Time 0:
        Track name: control track
        Text:       creator:
        Text:       GNU LilyPond 2.19.22
        Time signature: 4/4, metronome 3/16
        Tempo:      1000000 msec/quarter
        End of Track

Track 2:
    Time 0:
        Track name: \new:
        Control mode change: 0, 7100
        Note on: Channel 0, C3(48)
    Time 384:
        Note off: Channel 0, C3(48)
        Unrecognized MIDI event: (224, 0, 80)
        Note on: Channel 0, C3(48)
    Time 768:
        Note off: Channel 0, C3(48)
        Unrecognized MIDI event: (224, 0, 64)
        Note on: Channel 0, Cis3(49)
    Time 1152:
        Note off: Channel 0, Cis3(49)
        Unrecognized MIDI event: (224, 0, 48)
        Note on: Channel 0, D3(50)
    Time 1536:
        Note off: Channel 0, D3(50)
        Unrecognized MIDI event: (224, 0, 64)
        Note on: Channel 0, D3(50)
    Time 3072:
        Note off: Channel 0, D3(50)
        End of Track

And I would assume that the "Unrecognized MIDI event" messages are
tuning events.  64 would tune to point, 80 would tune 1/4 sharp, 48
would tune 1/4 flat.
