Waveforms 

Right:

 The 

Right 

jack outputs bipolar sawtooth waveforms 1, 2, and 3.

Left: 

The 

Left

 jack outputs bipolar sawtooth waveforms 4, 5, and 6.

Sigma (    ):

 The 

Sigma (    )

 jack outputs of all bipolar  

sawtooth waveforms.

Frequency / Pitch

Coarse:

 The 

Coarse

 knob controls the fundamental frequency  

of the oscillator’s core. It determines the fundamental pitch of the  
core waveform. 

• 

Turning the knob anticlockwise will decrease the frequency. 

• 

Turning the knob clockwise will increase the frequency. 

Fine:

 The 

Fine 

knob is used for minute control of the oscillator’s 

fundamental frequency and is relative to the frequency value set by  
the 

Coarse

 knob. It also determines the fundamental pitch of the  

core waveform.  

• 

Turning the knob anticlockwise will decrease the frequency. 

• 

Turning the knob clockwise will increase the frequency.

1V/Oct:

 The 

1V/Oct

 input

 is a bipolar control voltage input that is 

calibrated to 1 Volt per Octave. 

• 

This is traditionally used with pitch-related control voltages sent from a 
sequencer or keyboard. 

• 

Control voltage is summed with the values set by the 

Coarse

 and 

Fine

 

knobs.

LFO: 

The

 LFO

 toggle lowers the frequency ranges of the waveforms, 

allowing for oscillations within subsonic territory.
