6 V/OCT 

Use the V/OCT input as a second modulation input that modulates 
both filters in sync. This input corresponds to the volt per octave 
standard, which means adding one volt to the modulation signal 
doubles the CUTOFF frequency (in other words: tunes the filter one 
octave higher). Since not all V/OCT inputs in modular synths are 
calibrated the same way, you can use a flat head screw trimmer 
one the back to adjust the scaling of the V/OCT input. To calibrate for 
your V/OCT source, put up RESONANCE to maximum, INPUT to 
minimum, listen to the R OUT and use any chromatic tuner. Applying 
1 volt/1 octave from your source to the V/OCT input should result in 
the self-oscillating tone going 1 octave higher or lower. If the resulting 
pitch is flat, turn the trimmer CW. If it is sharp, turn it CCW.

7 STEREO

The STEREO section allows to create stereo effects when used 
in stereo, or detuned formant filtering/ring modulation when using 
the filter in mono.

The default state (with no effect) is with the STEREO knob centered.

When the STEREO switch is in the SPREAD setting, turning the 
STEREO knob CW will result in an increase in the cutoff frequency 
for the left filter, and decrease for the right filter. Turning it CCW 
has the opposite effect. 

In other words, with the STEREO knob centered, the cutoff 
frequencies are aligned, and the more you turn the knob in either 
direction, the more detuned these frequencies become.

When the STEREO switch is in the PAN setting, turning the 
STEREO knob to the right will decrease the output level of the 
left filter, and turning it the left will decrease the level of the right 
filter. This is a basic panning procedure, and it virtually moves the 
sound source from left to right when listening in stereo. However, 
when used in mono by listening only to the L OUT, the stereo knob 
crossfades between the L and R inputs.

Connecting a cable to the STEREO jack will change the function of 
the STEREO knob to an attenuator, which controls the amount of 
modulation applied. When turning the STEREO knob CW from the
