Roland S-MPU64 64-Channel MIDI Processing Unit

Features:
Using a high-speed USB results in an amazing response even for simultaneous multitrack performance
Digital connection via USB interface for high-quality, low-noise sound
Connects to any personal computer equipped with a USB connector, whether desktop or laptop
"Plug & Play" capability eliminates the need for the annoying settings required by personal computer connection (unlike ISA/PCI cards)
Power is supplied from a personal computer via the USB connector so no additional power supply is needed
Since the interface does not use serial and parallel ports, it frees up ports allowing a modem and printer to remain connected
4 MIDI Ins and 4 MIDI Outs accommodate complex multitrack sequencing
Individual LED indicator for each MIDI In/Out port
The driver (supplied with the S-MPU64) features a Patch Bay function for utilizing S-MPU64 functions to the fullest extent
Using a personal computer equipped with multiple USB connectors allows controlling up to four S-MPU64 units at one time (64 x 4 = 256 tracks)
