I wanted to make a V to S-trigger cable in order to use my Realistic Concertmate MG-1 with my other synthesizers. Untill now I've been using my Concertmate with the Keystep Pro. Because I'm able to change the CV output of the Keystep to S-trigger.

With this little box I'll be able to connect all my synth with a V-trigger CV output directly to the Concertmate. In this example I'm connecting it using the Moog Mother-32.

I hope the information in this video is helpful. Please let me know if you know better ways to do this. I'm a novice but I want to learn. 😉
Thanks for watching.
