Wilkie1 – you’ve brought up a point I’d not considered – the trimpot. Looking back again at the schematic, I’ve modified the LFO output section to include not only R23, but also R24 and P1 (the Rate pot) and a DPDT switch to exclude the internal LFO. The Rate pot may then be helpful in finding the CV reference to balance the CV swing at the FETs. (Potentially, as a better point at which to inject the CV. I present the modded schematic here for your consideration.
