Yes, those modern functional languages really bring back the joy to
hacking. :) The trouble with ML and Haskell is, though, while they
already have some facilities for graphics programming, at this time they
mostly lack other multimedia libraries. (And I'm wondering how suitable
Haskell would be for realtime stuff, given its lazy evaluation strategy.
ML certainly is, in fact it's been reported that in some cases compiled
ML is even faster than C ...)
But the world doesn't end there. E.g., there's Faust for audio
programming (developed at Grame, must admit that I haven't tried it yet,
but I certainly will), and (shameless plug) Q (http://q-lang.sf.net),
which already has interfaces to PortAudio, libsndfile (of course ;-),
MIDI, OSC, SuperCollider and whatnot. Q takes the route to represent
MIDI and OSC messages as high-level (algebraic) data types, so most
transformations (such as mapping MIDI input to SuperCollider control
messages) are almost trivial to implement. Q is also embeddable in C, so
you can use it inside a C/C++ program if you need that.

Yes, that's a nice twist. :) Apparently plugging together the different
FFTW algorithms becomes so complicated that they use OCaml to do
algebraic simplifications on the resulting graphs.
