Hey there is a program called WIDI http://www.widisoft.com that does a really awesome job at converting guitar to midi and it does it polyphonically. I know this could be done directly inside of PD just as well. Does anyone know where to find some tutorials on doing this with PD? I've played around with SMECK without the 6 separate pickups. Is there a way to make SMECK work with just one pickup? I haven't really looked at the pitch recognition part of SMECK which I ought to do.

Hi,

here is an 'audio2midi' testbench for mono signals I use with my violin.
Maybe it's a starting point for 'decent poly recognition', but I'm not sure how much work it will cost

Make sure you set the midi channel feeding the right inlet of [essai_sigmund_flow] with an integer.
