I'm a little lost in the bewildering array of music packages for Haskell, and need some help.

I'm looking for a the right set of packages and SW so that I can:

a) generate short sequences and play them immediately, preferrably in ghci,

-- but 'runHaskell Foo.hs | barPlayer' would be acceptable

2) generate MIDI files

I'm on OS X.

So far what I've found is: Haskore, the midi package, and the jack package - and then I'd need some MIDI software synth for the Mac, and Jack based patcher.... Or perhaps I want SuperCollider, and the Haskell bindings - but that seems rather low level for my needs here (I don't really need to patch together my instruments, and I don't want to have re-write the whole timing framework from scratch.)

So - What's a quick easy path here?
