The Doepfer MSY2 is a sturdy and straightforward tool for converting between MIDI and DIN sync connectors. If you use any older Roland instruments that rely on DIN sync then this device is extremely useful for integrating your older machines with newer MIDI equipment. The Clock output is a nice addition, I added a Korg Monotribe to my set up recently and it was very convenient to be able to send the Clock output from the MSY2 into the sync-in on the Monotribe. I had originally planned to modify my Monotribe to accept MIDI but having the Clock from the MSY2 means I've been able to get it up and running with my other machines immediately. If you need to convert between MIDI and DIN sync then the MSY2 does the job very well.
