Controlling Voyager with Teremin

[lesNiobides]

So, I attached the cables from theremin to voyager using the proper inputs but
only get a sound out of the Voyager when holding down a key, which would
require me having 3 hands to operate the theremin. I actually resorted to placing
a weight on the key to use both hands on the theremin.
Is there a switch on the voyager or something I'm missing in the set up?

Change the envelope gate to external.
