Subject: Lisp interpreter extern? Spectral Display?

Greetings folks,
As someone who hops back at forth between text-based and graphic-based
approaches to creating music, it occurs to me that a Max extern with a Lisp
interpreter would be a wonderful thing. That way one could use text to
certain precise ideas (such as the extremely useful "item stream" setup of
and then connect the output visually to various musical transformation
objects in a more or less free-wheeling fashion. This isn't to say that you
be precise
in Max, or that you can't be free-wheeling in Lisp, but certain ideas
better in one or the other domain. Anyway, has anyone out there actually
such a thing?
Also, am I to take the silence on the queries (by myself and others)
regarding simple patches that demonstrate spectral display to
mean that they aren't out there (that seems hard to believe!)?

Is there a new version of Videoin ?
I meen one which would work with MSP ?

I was working on a PPC update but ran into some QT problems.  I'll try to
get back to it soon, hopefully to finish by year's end.
