Single VCO with multiple waveforms

VCO

“Arch” 424 is a voltage-controlled oscillator. This VCO’s frequency range is wide, Can be used as VCLFO. It can produce four waveforms simultaneously: square, sawtooth, triangle, PWM and sine wave (sawtooth shape is not perfect yet). The frequency or pitch of the VCO is determined by tuning (Pitch and Fine) knob, and by the voltage present at the CV inputs.
You can control the pulse width of the square wave either by hand, or by voltage control – Pulse Width Modulation or PWM.

If perfect pitch is required better VCO is recommended. For a perfect sawtooth this is not recommended.
