Anybody here knows what kind of synth that The Commoderes used in their song "Machine Gun" It's a '70's song. I just want to know how can we program the newer synth to do this. I'm not worried about the clavi's. If you can listen to this song you will hear the synth lead with vibrato effect in the beginning which I think the keyboard player of The Commodores used the Mod wheel and then release it.
