Our current (2.4) process of doing a Perf to CC Binding requires that the CC be sent in from outside the program, after which it gets bound to the Perf that is current.
Once we have an elaborate set of these Perf to CC Bindings, it would be very desirable to be able to keep existing CCs and rebind them to new perfs. I can imagine more than one way such editing might work.
The big point is not having to resend the CCs into the program every time you want to change the bindings.
The CCs are already there, and already laid out (from before) in understandable order, etc. Now we want to do a new song, with new perfs. We may not even have an easy way to resend the CCs without jumping through hoops. Being able to just do such edits in Scaler would be a real boon.
