Stripping out the center & isolating the left side

[stvc]

I've got some trio recordings with bass left, piano right, and drums straight up the middle. I want to isolate the bass channel as much as possible to hear the lines clearly & transcribe them.

I'm almost there with Live's Utility plug. I can really suppress the drums in the middle, but then I'm stuck with a mono signal of bass & piano combined.

Any ideas how to get this happening using Live's native plug-ins?

Can't see a way do achieve complete isolation of the bass, but wouldn't it be easier to transcribe the bass if you just take the left channel with a mix of bass and drums / no piano ?

I'm kinda of going back and forth between bass & drums and bass & piano depending on which has the less sonic interference. The piano playing is much more sparse than the drumming & it's consistently in a higher register, so I tend to prefer using bass & piano.
