Hi, does anybody know an open source app to keep the play back tempo of a local sound file in sync with an externally supplied tick (eg via MIDI clock). The pitch shouldn't change of course. And I would be happy, if it was not a GUI based program. Think of merging a tempo-stable track with a live recording, where the drummer didn't play to a metronome, so there are slight tempo changes that should survive :-) . The click source for the sync would then be some beat tapping on a MIDI keyboard for instance. Thanks for any ideas, Yours, Jacob
