The Hungry Robot VCO is an all-analog, low cost, workhorse of a VCO. It can output triangle, sawtooth, and square waveforms simultaneously with tremendous bass response. The VCO has exceptional 1V/OCT tracking with FM modulation. The FM modulation input has a built-in CV attenuator as well as an inversion switch. The square wave has PWM with a built-in CV attenuator. As with all Hungry Robot "Modular Boxes" the VCO can be powered with a simple 9V DC, Negative Center power supply.
COARSE: Provides a wide sweep of output frequencies
FINE: Provides a narrow sweep of output frequencies for fine tuning
PWM: Attenuator for the PWM CV input.
FM: Attenuator for the FM CV input
INVERT: Inverts the incoming FM CV input. Toggle to the right to invert incoming CV
