Hi Gamuso, maybe there is no ready made product, yet, because everyone uses his/her own way. I'd recommend fiddle~ newly ported to 64 Bit by Volker Böhm. http://vboehm.net/downloads/ Also there: sigmund~ (more precise, but more CPU, too) and bonk~ (for percussive sounds). In M4L it's not possible to have a device with audio input producing MIDI notes. Instead you can analyse the signal there and use OSC or Max send/receive to communicate with a Max MIDI device and send the MIDI notes from there.

the IRCAMAX 2 Pack should do it. IM-Ianalyzer IM-NoteTracker

Thanks guys, I'm already trying with fiddle~ and those, but it's really weird there's nothing out there readymade... I love to expend hours with my max patches, but these days I'm preparing a concert, and can't afford hours and hours in front of the screen.

IRCAMAX2 looks good... but 150€ seems too much just for a device I need, also if I can't test before...

Thanks again.

It seems Max 7 made everything much easier, http://sonicbloom.net/en/whats-new-in-max-7-for-max-for-live-users-15-audio-effects-using-real-time-intonation-pitch-and-time-correction/ But I still don't understand this total lack of information... I've spent around 3 hours trying to find this, and it happened by luck.
