Audio Loops I import are not perfect with the tempo.

Post by monogee »

I find when I import an audio loop that's 4 bars long and adjust the loop to the tempo of the sequence, it is not perfectly adjusted to 4 bars. It goes a little beyond the 5/1/000 measure. Has anyone experienced this? Thanks.

If I'm reading correctly, it's a math issue. At X tempo, 4 beats = (made-up example) = 3.11125 seconds.
Audio can only be divided at sample points (no such thing as a fraction of a sample) so maybe it can only come out (again a made-up example) 3.11122. There's probably a fractional tempo that would solve that, but I'm not sure how to work the math.

That's my best guess to answer your question.
I have had trouble in the past even with MIDI loops- if they loop a long time like 30-40 minutes they eventually drift off the tempo. Seemed like a bug to me at the time. I haven't run into that lately, this was years ago when I was doing different things with DP. IIRC my workaround was to Paste-repeat the loop many times to the length I wanted rather than using DP's loop feature. I'm fuzzy on whether I did that with audio too, it's been too long.

Best way to import a audio loop is to know the tempo of the loop, set the DP sequence to that tempo, then import the loop.

I use DSP Quattro or other app.. hmmm I 'm forgetting the name.
