The Korg KMS-30 MIDI Synchronizer can be used to send MIDI information to the SYNC IN on any vintage analog synth or drum machine. I used it sporadically while working on music demos.  It’s in excellent condition and the AC adapter is included. I’m still looking for the manual; in the meantime, I downloaded the manual online and would be happy to send it with the purchase of this like-new MIDI unit.

If you look closely at photo #5, there’s a mark, or more of a dent in the middle of the unit. It has had no effect on its operation.

Here’s what you’ll find on the rear panel: 

- 1 MIDI IN 

- 1 MIDI OUT

- 1 sync IN 

- 2 sync OUT 

- 1 tape IN RCA

- 1 tape OUT RCA
