You'll have to ask the Yale music crowd why it isn't on Hackage.... But, their web site does have a page on how to get it: http://haskell.cs.yale.edu/euterpea/download/ But it basically boils down to getting it from github: https://github.com/Euterpea/Euterpea - If I recall, it has one or two dependencies that didn't build on the latest HP, but just required tweaking of their .cabal files to fix.... Wish I had written that down when I started!
Euterpea's Setup.hs imports the local ArrowWrap.hs which requires haskell-src-exts < 1.14.0. Euterpea.cabal specifies haskell-src-exts == 1.13.5, but 'cabal configure' doesn't apply that requirement to compiling Setup.hs. I ran 'cabal install haskell-src-exts-1.13.5' then 'ghc-pkg unregister haskell-src-exts-1.14.0' to fix this, but maybe there's a better way. I didn't have any other trouble building Euterpea or PlainChanges2 (after cabal installing the dependency versions that Euterpea.cabal asks for). Once I built it, this worked for me on my Linux to listen to it: $ ./dist/build/plainchanges2/plainchanges2 midi . $ timidity whole-composed.midi (SoundCloud claims to require Flash, which I avoid installing, so I couldn't listen to it there.) By the way, on https://github.com/mzero/PlainChanges2/blob/master/doc/Building.md the link to Euterpea's website is broken. -Isaac (because I'm interested in computer-generated/mediated sound)
