@audiosampling The leaking thing always happens when the sample is shorter than 6 seconds. Maybe that’s what happened there?
It’s nice to have a conversation about this in-depth stuff. Maybe some of you would like to check my sample guide for correctness? I’ve already been wrong about the looping thing, and the track names and engine names are wrong. http://gerotakke.de/op-z-sample/op-z-samples.md.html
I plan to correct those but first I’ll make custom base_freq a thing and I haven’t given up on the perfect loops, maybe I’ll just have to correct the fractional adjustments. I’ll let you know!
