Signal Flow
Dual Oscillators
There are two sawtooth based oscillators.
The oscillator outputs a sawtooth wave and a square wave generated from the sawtooth wave.
When nothing is connected to the "TUNE" input, you can vary the pitch of the oscillator with the "COARSE" knob.
In this case, the two oscillators will have the same pitch.
In addition, the pitch of VCO2 can be slightly varied using the "FINE" knob, so by mixing the sound output simultaneously with VCO1, a DeTune effect can be achieved.
Of course, you can also use it as an independent oscillator with separate pitch control by inputting a different CV signal to "TUNE" inputs 1 and 2.
PulseWidthModulation
The duty ratio of the square wave generated from the sawtooth wave can be changed using "PWM".
The "PWM" knobs 1 and 2 can always vary the duty ratio of the square wave, but the duty ratio can also be varied simultaneously with the CV signal connected to the "PWM" input.
When nothing is connected to the "PWM" input, the duty ratio of the two oscillators can be varied simultaneously with the VCO1 "PWM" knob.
This is also true if you input a CV signal to only one of the "PWM" inputs.
In this way, PWM can be flexibly controlled.
Oscillator Sync.
When the "OSC.SYNC" switch is turned ON, the pitch of VCO2 can be forcibly synchronized with the sawtooth wave of VCO1.
When oscillator sync is ON, it produces a massive, thick sound.
If you leave the pitch of VCO2 fixed and turn on oscillator sync, you will get an inorganic tone.
X-Modulation
X-Modulation (Cross Modulation) modulates the sawtooth wave of VCO1 with the sawtooth wave of VCO2.
When the "X-MOD." switch is turned ON, the sawtooth wave of VCO1 is modulated and mixed with the unmodulated sound before output. The degree of modulation can be adjusted with the "DEPTH" knob.
Only affects the VCO1 sawtooth wave, and has no effect on the VCO1 and VCO2 square waves .
