Same to you!

I don't think so. It's mostly intended to provide an alternate,
and un-typed api for a UGen.

Huh huh. Um, I can't remember what the P in pmsg stands for anymore.
As for them npmsg's... it's unclear whether they are equivalent to
pmsg's - another open problem in chuckian theory.

That too, though pmsg, for generality is always one string. So it's
f.pmsg( "coefs 0.2 0.1 0.4; 0.2 0.4" );
The UGen can define the protocol freely.

I think the key idea is that .pmsg is, so far, pretty worthless,
hahaha. Though it sounds like you've gotten how they are to work as
much as there is get. We'd love to hear about the new UGen, too!
There are a few new ones, mostly out-of-the-box filters, coming in
220.127.116.11 as well.
