Hello,

Yes, that has probably been my primary work integrating Csound and  
Haskell to date.  I would be very interested to hear from any users.

hCsound provides a Haskell interface to the Csound API, similar to  
what is available from Python or Java.  The haskore package,  
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/haskore,  
can be used to produce output csd files.  You may want to look at the  
dsp package,  
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/dsp, which  
provides many convenient dsp utilities such as fast convolution,  
matrix operations, filters, etc.

hCsound is still under development; I have some intended API  
improvements to improve interfacing with other C libraries (e.g.  
hsndfile/libsndfile), however I wanted to work on the build system  
first.  I'd also like to add support for iteratee/enumerators, which  
should be fairly simple.  I've got some more pressing issues to deal  
with, though (travelling to SEAMUS and my upcoming oral exam chief  
among them).  If anyone really wants any specific features, ask me and  
I'll see what I can do.  Of course patches are welcome too.

I don't want to evangelize Haskell too much, however I find it to be a  
very expressive language.  I've also learned to love static typing  
again, which surprised me greatly after the incredible verbiage of  
Java and C#.  I enjoy using Haskell more than any other programming  
language I've yet come across.

Cheers,
John
