Sidechain source/destination handling
A way to select where a sidechain source comes from.
Problem: when using multiple sounds (sub kick bass) with "BD" in the filename, sidechaining goes a little wild and uncontrolled because the sidechain input is listening to all the files simultaneously.
Solution: define 1 or as many as possible (depends on the internal software structure) tracks (also single sounds in a drumkit) as a sidechain source. Then select on every other track one of the provided sidechain sources, number 1 being default.
This will provide very much flexibility for sidechaining.
Additional: A "sidechain page" with some sort of overview which source is assigned to which sound (otherwise one might have a hard time to recall where the sidechain signal is coming from.
Also a legacy mode for older tracks and people who like it the way it is now
