Of course this is experimental and a user who uses these quarter tones makes it at their own risk. Currently, midi is produced for some monophonic instruments, for example quartertone flutes. Anyway, in paper, microtonal polyphony works more smootly. Even the new specification of midi at http://www.midi.org/about-midi/gm/gm2_spec.shtml states only commands for Master/Channel Fine/Coarse tuning, which means that the tunings of the tones in a polyphonic channel cannot be controlled separately. > One "solution" is to half the number of channels.

However, in future at some point, there may be also the twelfth tones. Then one may be totally lost with this kind of splitting. Should one split a twelfth tone polyphonic channel to six channels? Seems like here the ordinary MIDI specification is not complete and one could potentially consider porting audio also to some other format, for example to csound which gives more control on the tones produced.
