It's true, as Bill wrote, that Project Builder/gcc's generated code is
significantly slower when not optimized. It's hard to imagine that it
would be 200 ms slower, however. Does turning on the optimizer make a
difference?
I can't think of a good explanation. If you'd like to send me the
CodeWarrior and gcc-built versions of your app, I'd like to investigate
on 10.0.4 and 10.1.

Hello again,
I ported my app from 9 to X by using Carbon and MIDIServices. Another
strange effect occurs: When compiling my app with CodeWarrior under OS
9 and
run it in OS X there is "no" delay between NAPlayNote and its response
(Sound). If the app is compiled with the Project Builder (Carbon
Framework
and Quicktime Framework) there is a delay of about 200ms between
NANotePlay
and the Sound. I would like to use the Quicktime Instruments as an
alternative sound source for people without (expensive) MIDI sound
module.
Does anybody know the reason for this difference?
Have a nice day,
Helga
