Analog oscillator, based on the VCO from Roland's 100m system.
The VCO has individual outputs for sawtooth, pulse and triangle. While saw and pulse have a very rich sound full of harmonics, the latter produces a tremendous sub-bass.
Oscillator frequency is set coarse with the "range" pot and fine with the "pitch" control. There's a 1V/octave input and a nexponential CV input with attenuator.
The pulse width is set with the "manual" control and via CV. Compared to other VCO it sounds more dicreet as it ranges from 50/50 to 90/10 and not over the whole width range until sound cancellation. Super-wide modulations or ultra-narrow spikes are not possible but the VCO sounds awesome with the PWM at 50/50 (fully counterclockwise).
The System X VCO features oscillator synchrinosation which can be switched from soft sync and hard sync.
