The 2010 hard drive arrived today. I installed to run from the USB drive.

I loaded BIAB, loaded a song I had programmed, and set it to a matching
RealTracks style.

It plays for a eight or ten measures, and then the instruments drop out one by
one, eventually leaving only RealDrums playing. I switched styles several times
and had the same problem. Sometimes it starts with only drums playing.

Any ideas?
