Moog Music released this video today, which features Brian Kehew giving a tour of the VX-351 CV Output Expander for the Minimoog Voyager.

The video and sound quality of this video aren’t great, but Kehew, who’s done everything from play keyboards for The Who to co-authoring Recording The Beatles, knows his stuff and does a great job of highlighting how the VX-351 CV Output Expander turns the Moog Minimoog Voyager into a modular synth.
