Re: Auto-panner

Thanks, David.
@Vaughan
For a short test ... this compiles, but I can't listen to the resulting
pan in midi ....
I changed the PropertySet to ApplyContext with a lambda. This should
work in variables, as it returns an applyContext expression.
As with the previous solution, you have to care about the order autopan
is called.
It might be a good idea to either use a performer (engraver in midi
context) and/or to track context id's, so that each context is counted once.

HTH, Jan-Peter
