if you decide for midi notes instead of "i" events you have the
possibility to use quarter notes with two different midi channels: one for
the "normal" tempered notes and one a quarter tone higher. this is
actually how Open Music plays midi quarter tones.

You can give a floating point number for the note number. I know this 
works in Pure Data if you then use a mtof object  to extract the 
frequency. It's not part of the MIDI standard though.

There is yet another additional possibility: SMT - Standard MIDI Tuning.

oh ok.  i always have used NAPlayNote(), but looks like there is also
a MusicPlayNote, which takes a long as pitch value, maybe this is what 
you are talking about:

ComponentResult MusicPlayNote (
    MusicComponent    mc,
    long              part,
    long              pitch,
    long              velocity );

"The pitch at which to play the note. If the pitch is specified by a 
number 
from 0 to 127, it is a MIDI pitch, where 60 is middle C. If the pitch is a 
positive number above 65535, the value is a fixed-point pitch value. Thus, 
microtonal values may be specified."
