LFO adding noise to mix


Apologies if this has already been brought up or answered, but couldn’t find anything when searching.

I seem to be getting a lot of noise when using an LFO CV in modulation mode. Sending a sine wave to my mixer to pan for example will add a lot of unwanted crackle to the mix that I don’t seem to be getting with any other LFO source.

Any ideas? Has anyone else had this problem?
