Anyone seen this? I'm working on a SEQ file in RB, everything working OK, playback sounds fine. Then, for some strange reason, playback plays "faster"? I get a slight "chipmunk" characteristic. The tempo (on the screen) hasn't changed, but all tracks play back at a slightly (but noticeable) speed. If I close down and re-start RB, it goes back to normal, but randomly ramps up the speed. Any ideas on what might cause this? Thx.
