Mod-Demod

To ease the patching of modDemod effects, Signal 2 IN is normalled to Signal 1 OUT, thus connecting the two

circuits in series. Carrier/ CV 1 IN is normalled to Carrier CV 2 IN, so that in patching the desired Carrier Signal to

Carrier/ CV 2 IN, the modulation and demodulation processes share a single Carrier Signal. Patch Signal to be

processed to Signal 1 IN. Patch Carrier to Carrier/ CV 2 IN. Take output from Signal 2 OUT. The variation from circuit to

circuit will introduce demodulation errors that sound as distortions. Using the Strength controls, it is possible to

introduce more errors and to greatly reduce the integrity of the resulting signal. A nice variation on this patch uses a

pair of independent Carrier VCOs, which are tuned to same frequency, but not synced. Variations in waveshape and

Phase inaccuracies between the two VCOs will introduce more demodulation errors and distortions.

Octave UP

To ease the patching of octave UP effects. Carrier/ CV 2 IN is normalled to Signal 2 IN. Patch your signal to be

processed to Signal 2 IN. Patch the Signal 2 OUT into Signal 1 IN, take the output from SUM OUT. Use the Strength

controls to adjust timbre and blend of octaves.

DPO Supersaw

This patch uses voltage controlled inversion to derive a sawtooth wave from the DPO’s Final Output. Mixing it with

the VCOA Sawtooth produces a slightly unconventional, but nonetheless classic, supersaw.

Turn off all modulation to Final output parameters and the MOD BUS. Adjust FOLD panel control to ~9:00 so the

output is full amplitude but with no folds yet. Adjust ANGLE panel control to 12:00, listening for the fullest sound

available. Adjust SHAPE panel control full CW (100%) to “glitched triangle”.

DPO Final OUT -> ModDemix Ch1 Input

DPO Square -> ModDemix Ch1 Carrier/Mod Input

ModDemix Ch1 OUTput -> Mixer

DPO Sawtooth -> Mixer

Mix and detune the two sawtooths to taste. The sawtooth derived from the FINAL output will be one octave above

its original pitch, and it will also contain a slight “spike” at its peaks and troughs (because of its origins as a “glitched”

triangle, as well as varying slightly in amplitude every other period (because of the DC offset in the DPO’s square

wave). Combined with the unusual sawtooth shape on VCOA, which has a stronger-than-usual fundamental, this

patch produces a supersaw with character!
