What is the Cascade “invert” Jack?

What is the “invert” jack?
No where in the owners manual does it explain what that is!!!

Is it an input, an output, a CV?
I’m surprised that Qu-Bit didn’t take the time to document this!!


The Invert jack is a gate input which corresponds to the Invert button.

This feature will invert the envelope output’s shape.
For example, if your non-inverted envelope is at +5V, it will now be at 0V, and vice versa.
