Midi patch-bay and 8x8 midi mixer.
Useful for anyone with a large number of synths/ sound modules who would like to flexible midi data routing and scene memories.
Also has SMPTE in and SMPTE out connections for synchronising with reel-to-reel.
Very good condition, perfect working order.
Not useful as a computer interface as it only has serial port host connectors - hardware midi routing only!
