I'm having a strange problem in both Garageband (version 5.1) and Logic (version 8.0) ... any ideas would be most appreciated!
M-audio Oxygen61 keyboard
2.66GHz Intel Core i7
8GB 1067 MHz DDR 3
OS X version 10.6.4
When using the mod wheel to control dynamics, playback (after recording) is screwy. For instance, if I record two seconds of audio, upon playback the first second might have no sound, then somewhere in the middle the sound will abruptly cut in.
All data is being transferred (in the score view, all the notes are there) but not all is played back. If I have two tracks going, sometimes one plays back as entered, and the other cuts in at a random moment ... and sometimes both tracks have the problem.
The exact nature of the problem (i.e. when the sound cuts in or drops off) seems to be different every time I play a given example back. Sometimes all the notes play, but the dynamic drops or rises sharply at random moments (and not in a smooth crescendo, as was played).
This problem doesn't seem to creep up if I record something without manipulating the mod wheel. I'm not manipulating the mod wheel during playback, so if it's interfering with playback I'm not sure why, or how to fix it. Even if I turn the keyboard off after recording, the problem is still there upon playback.
I've already made sure I have the latest versions of everything (GPO, Garageband, keyboard drivers) except of course Logic, which is version 8.
Needless to say this is very frustrating. Thanks in advance for any help/advice!
