'sustain' is in cyclone.

It is modelled after the max' one, i.e. assumes a synth expects
multiple note-offs for multiple note-ons on the same key.
Besides, you would need to [route] to as many [sustain]s, as there
are midi channels used.

probably not in using it for scripting simple real-time tasks, but
I think a lisp-based extension, in an ideal world, would be
a great tool for composers.  What is needed though, is to find
a natural way for Pd objects to pass arbitrary lisp data around,
using Pd connections, and also for synchronizing Pd structures
(say, binbufs of qlist or xeq) with those in lisp.

Last week I have been trying to design, along these lines, a much
simpler tcl-based extension.  Design is not finished yet, but if
all goes well, it will eventually be a part of toxy collection
(called +tot I guess).  This is more like an exercise, and the
real thing should probably speak lisp, not tcl...  Unless, in the
end, it turns out, that there should not be any real thing in Pd,
just a kind of Pd-OM bridge, or the like, instead.
