Definitely interested in this too as I more-or-less want to do the same with the hybrid/stitched model I want to do for the future of my corpus-based sampler stuff.
The really tricky part for me, as always, is the latency since I would (obviously!) want it to be real-time, with no latency (actually there was a cool post on the lines forum where Ezra (Don Buchla’s son) was talking about negative latency with the electric marimba strikes due to how it was setup).
Now that I’ve been cracking on that sampler and kickass onset detection stuff, I’m going to try to revisit and improve the “transient replacement” stuff and then try doing a staggered analysis thing, initially just matching the nearest of each time window, but then trying to do the weighting towards having things that would concatenate nicely based on the before/after samples.
Curious how smooth things can get, with your platonic “1.0” concatenation, particularly for sustained/drone-ish material.
