2OSC/d plus VCO

You have to send the pitch CV to ALL of the VCOs there...if you're using the CV BUS to send your pitch CVs, just patch a short cable from each CV BUS point on the 2OSC/d to the individual CV inputs for the two VCOs there. If not, then send the pitch CV to a MULT, and split it three ways so that it can feed the VCO and the two 2OSC/d oscillators.

Remember: if you want something to do something, you have to patch up the necessary control signal for that to happen, or you have to patch a module's output to a "proper" destination...which, in a modular system, could be almost anything, so you need to get conversant with what does the things you want. For example, try patching the pulse output from one of those 2OSC/d VCOs back to the MOD input on the VCO itself, then slowly bring up the VCO's MOD DEPTH control with that patched...and the FM racket ranges from weird AF-rate flutters to inharmonic metallic FM yowls!

It's all about experimentation...Robert also points out that he made it a bit more difficult to wreck modules by adding buffering and protection (which also fixes CV sag, ergo no need for buffered mults!) to keep output -> output patches from wrecking things by sending voltage back thru the outputs. Do that without output protection, and you can theoretically blow a number of things...but Robert thought ahead! Best rule of thumb when exploring: things that work one way will work the same way on each subsequent patch on the same sort of destination (such as sending a pitch CV to a VCF's CV in, which then causes the VCF to "track" your pitches), but when you change this up (such as sending an oscillator output to another oscillator's MOD input, like above) you get a different BUT RELATED result. Just keep that last little bit in mind, and it'll make matters a bit clearer.
