Late to the party but glad you got it sorted. Those resonance trimpots inside are starting to get dirty and might need to be replaced in a few years. When I modded the 700S I used to own, I moved these trimpots to full size pots on the outside, so I could tweak that in real-time. In addition to the CV/Gate mod, I also did the audio in to the filters, but wasn't really that impressed. Only reason I sold it was because the person I bought it from originally said he really missed it, and I wasn't using it much at all. Sort of the opposite of GAS.
