Not sure if it's related, but there is a problem with Quicktime 7 and
Digidesign products. You might check to make sure you aren't using your
Mbox for other apps (check Digidesign CoreAudio Setup in the Digidesign
folder). However, I think your problem is probably due to lack of RAM --
all DSP is handled computer side.
Good luck -- I'd like to hear about your solution.
