Will the CP251 LFO oscillate to audio range? Maybe is you send a CV to it’s rate input?
Just wondering.
From my very limited knowledge and google, the lower limit of audible frequencies is around 20hz. The 251 will go up to 50hz by turning the knob and according to the manual if you apply a positive voltage (you can do this with the mixer offset) the lfo will reach a “maximum frequency greater than 100hz.” So it seems pretty limited, what were you thinking of doing with it?
Yes, the LFO can hit auido range pretty easily actually. (I just tried it.)
You can even make it go faster by modulating the speed with another LFO.
I will do more experimenting with this in a period of time. Right now, I am working on something spectacular. 
I just like audio range osc modulation. It makes a cool sound when you modulate a filter. Adds some grit. I just sold my Odyssey, and I don’t have another synth with osc modulation.
Yep, I use the 102’s carrier out for filter cutoff modulation.
