Awesome!
I had never noticed the baseline of 2 in the Voltage Guide–thanks!
By the LFO1/2 code, the default freq is 1, the default knob position is 1, and there’s no multiplier in setPitch; I didn’t clock the low frequency, but I checked by ear and the highest knob position is 1,024Hz (per the manual), not 2,048Hz.
I think what’s going on in LFO1/2 is that there’s no external direct voltage control over the pitch (just FM, which is obviously a different thing), and so the module can use whatever internal “voltage” it likes for the knob to talk to the oscillator core. It’s basically just a convenient way of scaling the knob (the way you would use different resistances and baselines for hardware pots). No other module would see the actual value and so it doesn’t matter. If there were an LFO Rate input, it should (and presumably would) follow the baseline, where an input voltage of 0 would yield a LFO rate of 2Hz.
