If I have 2 long static samples on 2 different tracks and I assign rate (timestretch) and/or pitch to a scene, will messing with the fader during playback affect sync?
It seems so, but to be honest I’ve only recently tried to work with long static samples so it might be a used error…
What I’m trying to do:
After composing a whole song on the OT-A4-ND2 I’ve sampled it twice, once drums only, the other everything else;
i want to play back the 2 files while playing around with scenes while triggering patterns or one-shots to create fills/risers/etc.
The aim is to have a fool-proof song I can perform on the OT only, fool-proof as based on playback of two tracks, but still with some human interaction live.
If you use a scene to adjust parameters identically on both tracks then in theory the same changes will apply to both tracks, so sync should be maintained. In practice, especially over a long duration, it may not be perfect sync.
If there are problems, you might consider dividing your song-long samples into shorter chunks (where any relative drift might be less apparent) and sequencing them by hand or in the OT’s arranger.
I found out a workaround that works for me, instead of changing pitch/rate on the track I’m playing back, I have a new track that records and plays back the track I want to affect, and with the crossfader I fade between the original and the recorded track.
I added a feature to the Octachainer sample slicing tool a while back intended for the divide idea PeterHanes suggest. You can load a long sample, set the BPM and then tell the tool to make a slice every X steps, where X would typically be the pattern length. That way, a long “playback” sample can easily be mapped to patterns and stay in sync.
