Have you used M-Audio's Project Mix I/O -sound card/controller with MAXMSP?
I'm searching for a portable soundcard/controller for small concerts with acoustic instruments and live-electronic.
I use OSX 10.3.9 and Powerbook G4.
Other altenatives are the Digi 002 Factory and Yamaha's 01x.
advantages for these two are, that they also work as a standalone mixer.
My friend told me that it could be possible also with Project Mix I/O,if you write a small MAXMSP patch for that.
