The ACL Multi-Function Discrete VCO was developed with highest performance, precision and detail in mind. The discrete, transistor-based circuitry delivers an impressively powerful analog sound with a pleasant Vintage character . Nevertheless its characteristic as a single oscillator with five waveforms is a no less equipped sub-oscillator on board, which follows most control elements of the main oscillator well, but has its own controller set for pulse width modulation of its five waveforms.
The ACL Multi-Function Discrete VCO can also be switched in the LFO mode and offers soft and hard sync with variable VCO synchronization from not at all to full. The Vernier dial is used to control linerar and exponential FM as well as to find the desired frequency with extreme precision.
