I’ll vouch for VCO3 – the frequency range of that thing is incredible.
Ultrasonic to the “is-this-thing-oscillating?-oh-yeah-I-guess-it-is” LFO
effect. I’ve coined a new unit when measuring the low end freq of VCO3 –
the CB (Coffee
Break). Low end of my VCO3’s is around 1.32 CB’s, according the the CB
setting of my frequency counter.

Another cool thing is that the hard sync synchronizes to my keyboard
trigger, which is pretty nice for LFO use. Of course, at audio frequencies,
the sync sounds great, too…..

A great sounding, useful as heck VCO.
