Resurrecting this topic for a related issue:
I'm using BGB to render songs and then chopping those renders into loops for use in other software. I'm using a high pitched pulse instrument at the beginning and end of the song to indicate where the render needs to be trimmed and I'm pretty confident that I'm doing a good job of trimming at the exact sample point where the actual song starts/stops. This is all being done with 2-4 minute long files.
When I load the wave into BeatCleaver or the Renoise sampler to chop it up I just cannot seem to get the perfect loops I'm hoping for. If I go by tempo detetection there's always a tiny slice left at the end and the loops are all off-set slightly. If I use an option to slice into a specific number of equal size chunks it's a little better but still drifts enough that (for instance) the first hit of a loop is missing it's impact.
So with all that said: Am I dealing with "tempo wobble" from lsdj in bgb, poorly trimmed wave files, or tools that aren't up to the task of slicing "big" files?
