Not quite. More like "muting tracks doesn't speed anything up anymore". And track export is done through muting. On to some forensics... Before rendering, I added code to print out all tempo changes and it looks like the sync problem comes from the 780 BPM change at tick 0 being delayed by up to 3 ticks in ~50% of the cases. All the other tempo changes seem to come at their correct times, or at least at the same tick on every render. (This in 0.9.91, the variation was a lot worse in 0.4.15) The few milliseconds this translates to usually isn't much of a problem on playback or when you export the whole project, so it could be that nobody has noticed this jitter much before. -- [email protected] softrabbit on #lmms ------------------------------------------------------------------------------ Subversion Kills Productivity.
