Moog VX-351 Control Voltage Expander for Voyager
More On The Way Notify me

Add More To Your Moog Voyager!

The VX-351 Voyager CV Expander provides all the Control Voltage (CV) and Gate outputs of the minimoog Voyager. Control Voltages are the signals used inside an analog synthesizer to cause changes in the sound produced whether pitch, timbre, duration, or loudness. A Gate signal is used to turn a circuit on or off. For instance a gate is used to trigger the envelope generators of an analog synthesizer, which causes a note to sound. The minimoog Voyager has 10 Control Voltage and 4 Gate Inputs. The VX-351 contains 19 Control Voltage and 2 Gate outputs generated by the Voyager's analog synthesizer circuits. In addition it contains two 4-way mults for distributing a single CV to multiple destinations, and two attenuators for reducing the amount of a CV.

Add the power of modular synthesis

With the VX-351, the Voyager attains the power of modular synthesis. Standard patch cords can route a control signal (for instance - a LFO triangle wave) back into the Voyager's CV inputs (for instance - the Pan control input) for a host of new modulation possibilities. Highly complex and fascinating sounds can be achieved.

don' purcahse a Minimoog Voyager without this key accessory

Thanks to my sales engineer Andy Rice who suggested this must-have expander for the Minimoog Voyager Select I recently purchased. In combination with the MF-104 analog delay, the range of timbres I can unleash range from evolving swirls of rich color to complete sonic mayhem. Note: Don't believe everyone on the online message boards who tell you only a 1970's minimoog will do and that the new Mini's sound sterile; I have owned and played both the Model D as well as a Moog Prodigy, and while the original stuff does sound wonderful, my guess is alot of those people mostly just audition presets, never spent serious time with a real Mini, and wonder why it doesn't sound like exactly (insert favorite Mini playing artist) out of the box with no effects or tweaking. The Voyager does sound a little different than it's "grandpa" Model D, but if you are buying based purely on nostalgia for the Minimoog D you should save your money anyway. On the other hand, if you want to go further in terms of modulation, creativity, and control capabilities than any 1970's portable mono synth ever could, buy a Minimoog Select with the MF 104/VX-351, get comfortable with leaving the presets and turning some knobs, and clear some time from your schedule, cause you won't want to stop. I couldn't be happier with this purchase or my experience with Sweetwater. Andy will definitely get my call when I am ready to add to my synth collection or recording gear.

Sweetwater Advice

Austin Moss

Wouldn't it be nice if you could have a Moog modular for less than 5 figures? For less than 3 figures you can add those capabilities with the VX351. I used one of these on an install recently and the control and possibilities this added to the Voyager were insane! In less than 5 minutes we were routing LFOs and envelopes to and fro. Don't forget the patch cables!
