I'm all for, like the flexibility and indeed it doesn't complicate too much,
does it?
But I think this can also be done using the string/tree representation:
/stereo1/balance
/stereo1/gain
/mono1/pan
/mono1/gain
/5.1surround1/...
/5.1surround1/...
/5.1surround1/...
This also needs parameters to be dynamic.
