utility VCO
The utility VCO has volts per octave tracking across a huge range, this can be an LFO down to a tenth of a hertz. The hard-sync input allows for LFO reset, a rare feature on a proper analog VCO.
Triangle, Saw, Square and Sine output. PWM CV, FM attenuator and a coarse/fine control are standard. Analog temperature compensation is achievable with EITHER an NTC or a PTC, because sometimes those are hard to find, this PCB supports FOUR different tempco schemes. This somewhat complicates the DIY build guide. All 0805 or SOIC sized, it is hand-solderable if you're so inclined.
Designed to use cheap parts and no trimming, the accuracy is utility functional it runs as a standard osc, or FM squelches, or basslines as you need for your eurorack play.
