Actually, the artifacts are the key to the process.  It's not a
'pure' subraction (not removing the exact sounds that were
part of the base) but a different way of building new layers.
For instance...you might play a gritty major chord into a loop....
By playing the major third in 'subtraction' mode the third is slowly
backed out of the mix (roughly)...and then playing
a minor third...the loop just changed feel.  This could be a slow
organic process...not like switching tracks on and off.
