replay/remaster stem separation?

Hi,

I've have the full ripx suite and have been using it to extract drum tracks for practice sessions.  The final stem is OK and usable, so I guess that's a positive, however I'd like to improve the clarity and I guess cross-talk.

1) The extracted drum mix sounds a bit like its underwater

2) In quite parts (no drums playing) you can hear elements of the other tracks bleeding through.

It got me thinking if there is a way to 'replay' the track using AI in the same way images can be cleaned, can audio be similarly cleaned?

Has anyone successfully turned an extracted stem to midi to be re-drummed?  I have melodyne studio, but haven't had much luck with that.

Just fishing to see what other people have managed to do

Cheers
Jim
