Bill and friends: It's great if this is going to work, because I'd love to
use it. My remark was based on the fact that for me fractional pitches still
didn't work with QT6. I had downloaded QT6 following these remarks from
Chris at Apple, and I quote:
"The QT APIs are deprecated and we highly encourage developers to move over
to using AudioUnits... Anyway, a bug fix in the latest release of QuickTime
6 (In Jaguar) should support the fractional pitches as they were originally
meant to work."
Nonetheless, my attempts to use a fractional value in NAPlayNote under QT6
produced no change in pitch, which makes me think that Richard might be
encountering a similar problem with regard to pitchbend. I'm not using
Jaguar; maybe that fix Bill mentions requires the presence of Jaguar. In
which case, though, I couldn't really use it as a program feature. But the
bit about deprecation caused me to conclude that Apple had no plans to do
further work on this admittedly obscure feature in QT.
If I can get fractional pitches to work with the QT6 now available for
download I'd be delighted; I can think of some fun things to do with it.
Yours, Jeff
