Hi Lucas, You're a very brave man. Go for it. While you're in there, see if you can get it to record for maestro-2. I seem to recall Julian saying it didn't work. He'd be grateful. Can you clarify one thing? You say: > I see this similar behavior on 4.8. In general the small files are the > ones that do not play. I too a small file that would not play > ... Does that mean waveplay exits but with now sound? Or is it as I saw on 5.0 that it hangs. You have to ctl-C to get the shell prompt back. I thought we had different behaviors on 4.8 vs. 5.0. k.
