Matriarch - Mixer and using CV

I read in the manual, and seen some videos about the mixer.

It says you can not only send audio to the mixer patch points, but also cv signals to control the signal.

I tried putting a triangle LFO - > osc 1 In. It kills the sound , i only hear sound if triangle LFO goes into audio rate..

How do i use the mixer inputs with cv ?

When you do that you are replacing the normal osc 1 signal w the LFO. I think want you want is take the osc 1 wave out and put that along w the LFO into one of the quads and then send that to the mixer for osc 1.
