Uggh, I knew that example would confuse the issue.  I demonstrated the
more flexible case.

Which I pointed out below the example.  But this is *COMPLETELY* dependant
on the synth.  When I play the same note 3 times in my sampler, I *do*
want the tail to play.  When you play the same note 3 times in your
e-piano, you do not.

Yes, but that implies some knowledge between the sytnth and the sequence.

...for a piano.  This is NOT the general case though.  By forcing this to
be the protocol, you gain nothing, and you impose restrictions.  That's
not good.

It's just as easy to use a new VVID for each voice.  If you're a piano,
you can floorf() the pitch.  If it is the same as an existing RealVoice,
kill that RealVoice.  The key is that it's all *inside* the plugin, where
that decision belongs.
