Instruo Cnoc

MUSICAL FEATURES

The Cnoc is a fully analog, voltage-controlled, two-stage function generator.Born from the West Coast sound synthesis philosophy, this kind of function generator goes far beyond the capabilities of traditional envelope generators. With 2 modes (AR, ASR, Looping), positive unipolar output and bipolar output, the Cnoc is ready for any patch.

• AR, ASR, Looping, 3 envelope modes
• External control of attack and release stages
• Positive unipolar and bipolar, two outputs
• Assignable gate output
• Manual trigger button
• Slew limiter function
• Two response curve settings

HOW TO USE

Patch Examples

West Coast Synth Voice

Overview: The sequencer triggers Cnoc simultaneously by sending a voltage to the oscillator . The unipolar output of Cnoc opens a wavefolder, allowing the oscillator signal to pass through.

Audio path:

• Patch the oscillator's sine wave to the wavefolder's audio input.
• Monitor the wavefolder output.
• Sets the wavefolder fold amount to the minimum value.
• Set the wavefolder symmetry bias to any position.

Control pathway:

• Patch the 1V/Oct output of the sequencer to the 1V/Oct input of the oscillator.
• sequencer gate outputSignal Inpatch to
• Fashionthe switchARmode.
• Response curveSet the switch to any position.
• UnipolarPatch the output to the wavefolder's CV input and set the corresponding CV attenuator to any position.
• ア タ ッ クwithreleaseset each fader to the desired position.

East Coast Synth Voice

Overview: The keyboard triggers a Cnoc module as it sends voltage to the oscillator . The Cnoc 's unipolar output opens the filter and VCA, allowing the oscillator signal to pass through. To create a more traditional East Coast patch, use separate Cnoc modules for the filter and VCA .

Audio path:

• Patch any waveform output of the oscillator to the audio input of the filter.
• Patch the filter's audio output to the VCA's audio input.
• Monitor the VCA's audio output.
• Sets the base frequency of the oscillator to any position.
• Set the cutoff frequency of the filter to any position.
• Set the filter resonance to any position.
• Set the VCA level to minimum.

Control pathway:

• Patch the keyboard's 1V/Oct output to the oscillator's 1V/Oct input.
• keyboard gate outputSignal Inpatch to

• Response curveSet the switch to the right position.
• UnipolarConnect the output to multiple.
• CNCpatch one copy of the CV signal from the filter to the cutoff CV input of the filter and set the corresponding CV attenuator to the desired position.
• CNCConnect a second copy of the CV signal from the VCA to the CV input of the VCA and set the corresponding CV attenuator to the desired position.
• ア タ ッ クwithreleaseset each fader to the desired position.

CV Slew Limiter

Overview: This patch is compatible with the previously mentioned West Coast Synth Voice . By smoothing the sequencer voltage through Cnoc , it creates a portamento (glide) effect between consecutive notes.

Audio path:

• Patch the oscillator's sine wave to the wavefolder's audio input.

Control pathway:

• Instead of directly patching the sequencer's 1V/Oct output to the oscillator's 1V/Oct input,CNCcomesSignal Inpatch to
• FashionSet the switch to the left position to select ASR mode.
• Response curveSet the switch to any position.If we choose the left position linear response, the result is more obvious.
• UnipolarConnect the output to the 1V/Oct input of the oscillator.
• ア タ ッ クwithreleaseset each fader to the desired position.ア タ ッ クfader sets the amount of portamento between rising notes,releaseFader sets the amount of portamento between falling notes.

Quadrature Modulation

Overview: This patch uses two Cnoc units . The first Cnoc is configured to generate a one-shot triangle wave function. The gate signal generated in the release stage triggers the second Cnoc , which is configured to generate a one-shot triangle wave in the same way as the first . The gate signal generated in the release stage of the second Cnoc re-triggers the first Cnoc. This cyclical patching creates two triangle waves that are 90 degrees out of phase with each other. The two Cnoc units continue to re-trigger each other in a continuous sequence. One triangle wave controls the amount of wavefolding, while the other modulates the amount of filtering, creating quadrature dual timbre modulation.

Audio path:

• Patch the oscillator's sine wave to the wavefolder's audio input.
• Patch the wavefolder's audio output to the filter's audio input.
• Monitor the audio output of the filter.
• Sets the base frequency of the oscillator to any position.
• Sets the fold amount of the wavefolder to any position.
• Set the wavefolder symmetry bias to any position.
• Set the cutoff frequency of the filter to any position.
• Set the filter resonance to any position.
