rather than rely on people sifting through the attachments in the mailing list archive, i've finally put nqpoly on my website. the patches are still messy and the documentation is kind of hasty.
what's nqpoly? it's an abstraction (yes really, not an extern) that kind-of does what the "poly~" object in recent version of max does.
(automatic polyphonism, granular synthesis).

let me know if you use it, and feel free to ask me questions about it in email if you have trouble.
