I've never used it, but it has been around for a while. Native
Instruments used to sell it from their web store, but it looks
like the Midiman borg have taken them over.
Thanks for sharing your experiences!!!!!! I wish there were a cheap
keyboard with sound, features AND USB and knobs.
FWIW, I have a MOTU Micro Express USB, and it works fine with
my iBook, Power Mac, and Athlon (SiS 735 chipset). I use an
aging Kawai K11 as a controller, but I can unplug it from all
the rest of that crap and use it all by itself to make what passes
for music in my world -- something you can't do with any of the
MIDI controllers. It can suck to be tethered to a computer if you
want to jam with friends.
