Regroover

Regroover is only for 30 seconds chunks, and they require manual align due to phasing issues - additional silence is added in the beginning and ending.

“Get your 30-second drum clip, then drag and drop it into Regroover.

Make sure to de-select the Sync option, as it will time stretch it by default.

On the right-hand side, I recommend changing the split to 6 layers instead of 4, simply for flexibility.

Once it has processed that, you can choose export -> layers."

There was a report that probably newer versions might not be feasible for this task anymore.

 

In other words:

It’s much more hassle to use it than drumsep, but it’s very good “if you need particular sound and not about pattern etc.

1. separate drums from whole track (demucs)

2. Cut drum track into max 30 second cuts [regroover limits] and ideally   cut right on transient, some space before kick helps,

2. You use regroover for the first time and for example try to separate to 4 tracks, just so overall separation.

3. Those separation sums exactly to that is given, sometimes it just need to be realigned few ms.

4. And if for example kick still has some not needed parts, you just regroove it once again.

 

If are looking overall fast and for patterns, drumsep. Regroover for painfull but precise job. Also in most cases hihats are trash, but snare's and kicks you often can find perfetclu usable ones. I'm not sure about metal but overall.”
