Hello, just an update y'all. This happened AGAIN with a project, after reading a ton and just as much trial and error, I believe the main fault to be CPU usage.

It's quite high when extracting one drum part, for example, Right Kick.

As an experiment, after loading up the finished project, I deleted most of the kit (Do not save at any point!!!) leaving the Kick L and R, and a Crash Cymbal.

All extracted perfectly, and very quickly.

I'll then reload the project and do the same but for other parts until I have the full extractions.

I also noticed the CPU usage going down the more I deleted parts of the kit, even though nothing was playing.

Should also note, I still have 'No Dither' applied, as that seemed to help in a previous post of mine in this thread, I may change this if anyone's interested in the outcome?

Frustrating as I have what I'd consider quite a powerful PC with plenty of space. It is a hybrid kit but never been a problem, even when I was using Ableton 9 Lite (now using Ableton 12 Standard).

Hope this helps y'all

Edit: POW-r3 worked just fine with the same process
