‘sources separation problem’
Yup. this is the thing.
How do you split sources once joined?
For music, onset time in groups seems to be key.
I think something similar may apply here .
Also : how do you know what to group?

 Ok, so it _does_ take multiple passes (or did in 1994). Hoping to find shortcuts but it’s a bit of relief that yes, it is not a simple problem to solve.
