The Shuttle Mate merges MIDI streams from DIN and USB sockets into one MIDI flow which is available simultaneously at a USB and a DIN output socket, making it a perfect companion to Endorphines' Shuttle Control module. However it can also operate on its own. Since the module is USB powered it can be used totally independently as a standalone device from the Eurorack-power. 

With the Shuttle Mate you can connect more than one device that delivers clock and MIDI signals with the Shuttle Control. 

The inbound and outbound USB connectors are both bi-directional I/Os
