Roland sounds module with USB and audio interface. 2 SFX slots for Roland expansion boards. Can play SMF and MP3s. No styles. Uses USB keys. No info on polyphony, or size of ROM.

Sounds pretty cool for OMB software fans. Laptop with a controller and one of these and you're getting closer.

Robert, 128 polyphony..

Actually, this can replace the laptop on the job..

Fran: If you need arranger keyboard-type functionality like backing styles based on chords you are playing in realtime how can this replace the laptop. I see SMF playback but I don't see that functionality.
