WAVEFOLDER

The WAVEFOLDER of VCO2 is a unique and completely original circuit. It folds and distorts the SINE,
TRIANGLE, INVERSE SAW and everything in between creating subtle rounding of the waves at low
settings and rich metallic overtones at more extreme settings (pictures 13, 14 and 15).

The WAVEFOLDER slider controls the amount of wavefolding. Even at the most downward position this
circuit introduces some distortion to the waveshape.

It’s possible to use the SINE from VCO1 (normalized) to modulate the amount of wavefolding. The
knob is an attenuator for this modulation. The slider acts as an offset. You can override the internal
normalization by patching a signal into the FOLD input. This input accepts biploar signals. The knob is
an attenuator for this external modulation.

With the slider in the down position the maximum wavefolding is achieved with +5V. Sending in 10V
(or maxing out the slider and sending in 5V) will mangle the wave even more (picture 16, 17 and 18).
Negative offsets (= sum of the position of the slider and the modulation) completely attenuate the
signal resulting in silence. This feature can be (mis)used as a makeshift VCA for VCO2.

LOW PASS FILTER

The LOW PASS FILTER in both VCO1 and VCO2 are identical. The SINE from VCO1 is used as a
modulator. You can find more information in the section about the LOW PASS FILTER of VCO1.
