DoepferA-111-3 Micro Precision VCO / LFO

Doepfer A-111-3

The Doepfer A-111-3 Micro Precision VCO is a 100% analog triangle-core VCO based on the A-111-2 Precision VCO but in a mere 4HP. The module features precision rectangle, sawtooth, and triangle waveforms and boasts a generous frequency range from 0.001Hz to 20kHz. Additionally, the module tracks at an impressive 15 octaves and features a switch that toggles between LFO and VCO modes. There are both exponential modulation and frequency modulation inputs, plus an additional PWM input with dedicated adjustment knob.
