It looks like it's the particular file that I was working with. Looks like it may have gotten corrupted. It was a file that I've used with several different external instruments over time, and I'm wondering if that's what corrupted it.

I'm hitting alt z, and it keeps saying that the audio engine is turned off, but it won't turn it on. Any ideas? Thanks. Omar Binno My Space: www.myspace.com/omarbinno
