I have some (very expensive) software called Reaktor. You draw boxes and

with it.
That sounds exactly like PureData - you can also do graphics as well
with PureData, the demo I saw was very cool. Of course, PureData is
written in C with Haskell as an extension language.
Reaktor is rather nicer to use than PureData though, in that it's designed
to work with mainstream sequencers (or any VST - I work with trackers
myself) and be used by non-hackers. Also, I'm not entirely sure it's fair
to say that it has Haskell as an extension language as such - but Claude's
slides'll give a better explanation than I can.
Reaktor has a few limitations though.
1. It's virtually impossible to debug the thing! (I.e., if your synth
doesn't work... good luck working out why.)
2. It lacks looping capabilities. For example, you cannot build a
variable-size convolution block - only a fixed-size one. (If you want to
draw *a lot* of wires!) If you look through the standard library, you'll
find no end of instruments that use a "hack" of using voice polyphony to
crudely simulate looping... but it's not too hot.
Would be nice if I could build something in Haskell that overcomes
these. OTOH, does Haskell have any way to talk to the audio hardware?
