Does anyone know what the story is about microtonal intonation under
QuickTime? According to the QuickTime docs, NANotePlay is supposed to accept
fractional pitches, though the meaning of the fraction is poorly documented
(logrithmic, or what?). I'm doing this with OS 10.1.5, and in any event, it
doesn't work: QT clearly understands the format, because it plays the
requested midi pitch even though it's shifted - but it ignores the
fractional part. I've tried doing this with the pitches all shifted up what
should be about a quartertone: e.g., middle C would be 0x3C7F (3C is middle
C; 7F is halfway though the unsigned fractional range of 0 - ff). What I get
is just the same pitch as if I had supplied 0x003C.
It would be a very fine thing if this were made to work. I figure I must
have the format right, given that the basic pitch is understood. Can someone
from Apple comment on any plans regarding this?
Thanks, Jeff Evans
