I was in genova for the eyesweb week which was very interresting.
And among other things I discovered that there is now an eyesweb community web forum at http://eyw.free.fr/ where people can share news, experience, patches, C++ code for the eyw blocks, tips and tricks and links toward new media resources.

Please go visit it http://eyw.free.fr/

nmfdemix is now available for mac OSX and I've added stereo file support.
both versions now have an installer so that you can use it from everywhere.

I've written a commandline demixing tool based on Non-Negative Matrix Factorization thanks to Arhsia Cont's work and interrest in NMF for polyphonic music analysis.
