Adding or subtracting time from a measure
Is this possible? I do not want uniform measures. I would like them to be slightly longer or shorter by milliseconds when played in audio files. I think I can do this with the tempo settings. How sensitive are the settings? I mean, rather than 80 bpm, can I have 79.999, and to what place value? that might be the only option. But it there some way to adjust the milliseconds in audio? So that, instead of 332 milliseconds, I could have 331?
Reason: I'm interested in getting a more natural feel to the time in audio playback. Human beings don't play instruments in absolutely uniform tempo.
