Ahhh, that's probably where I found it...

Anything with a decent number of UARTs would do indeed (nope, that 
excludes the AVR/Arduino unfortunately).

Link? You could of course increase the host bandwidth and make sure you 
don't send to much data to a single port at any time. Things get a bit 
more complext, though.

The question, though, becomes: If you get into modification of MIDI 
drivers and custom PIC code, why not build the interface using a 
USB-enabled PIC or similar from scratch?
