I recently multi-tracked a live show which required the use of an additional un-synchronized recorder. I used a buddy’s Korg D3200 to record an additional 6 tracks of 44.1kHz/24bit WAV files. I figured if I recorded in 44.1kHz/24bit within Cubase, I would only have to sync the additional 6 tracks once at the beginning and that everything would remain in sync.
Unfortunately this does not seem to be the case. After importing I can easily sync the beginning of the project, but ~20 minutes into the show you can begin to tell that it has drifted. After an hour into the set, it’s close to half a second off. The drift seems to be in the negative direction, that is events are coming in early, relative to the natively recorded Cubase tracks.
I opened the pool and noticed all imported audio has “elastique Pro - Time” under Algorithm and a slightly different tempo, (120.05 vs. default 120.00 for the native tracks). Changing the algorithm to “Standard - Mix” to match the native recordings does not appear to have an affect, nor does matching the tempo (note that none of the audio files are in Musical Mode, but my imported tracks do change position if I play with the project tempo).
I’m not sure why a time stretching algorithm is even being applied to my imported audio. Does anyone have an idea as to what it going on? Fortunately, the additional tracks only contain ancillary audio that only need to be present every now and then, but having to re-sync things numerous times will be kind of annoying, and I’d like to know what I’m missing.
