[PD] Gating

Yes, thank you. In combination with
zexy's [index] they will do it
having symbols as output selectors.
I've been also looking at [pyext].
It's great for quickly
implementing control objects
that are better expressed
programmatically and for
which performance is not critical
(so C/C++ is not a sine qua non).
