Roland SBX-1

The SBX-1 lets computers and electronic instruments communicate and synchronize with each other. It supports a vast array of both analog and digital devices through DIN SYNC, MIDI and USB, and any of these can be the master clock source. You can use the SBX-1 itself as the master sync and control your external devices with its rock-steady internal clock. With hands-on control over timing and groove, and support for CV/GATE, the SBX-1 is far from just an ordinary sync box.
