Description

The ACL Multifunction Discrete VCO is a fully discrete oscillator with a multi-waveform, syncable sub-oscillator, for layered and detuned voices. TUNE is a ten-turn precision dial beside a COARSE control, and the FREQ switch picks a high or low range. Both the oscillator and the sub-oscillator have their own pulse-width modulation section, with a manual PW knob, a CV attenuator and a CARRIER switch choosing which waveform the pulse width shapes; DETUNE sets the sub-oscillator against the main one. Linear FM, AC or DC coupled, and exponential FM, a SYNC section with a threshold and a slope switch, and five waveforms from each oscillator on their own outputs complete it.
