Page 2: Introduction
1 INTRODUCTION The ’CIZZLE’ is a dual digital ’phase distortion’ VCO inspired by the classic Casio ’CZ’ series synthesizers. It brings the specifics of ’CZ’ style phase distortion (PD) synthesis into Euro- rack with the inclusion of primary and secondary oscillator layering and detuning (with up to 8 voice chord generation), extended morphable PD wave generation algorithms, unique reso- nance wave generation, plus specific ’end of chain’... -

Page 5: Osc A And B Frequency Controls
4.3 OSC A and B Frequency Controls The upper section of the module provides controls and inputs for setting the pitch of the two oscillators. Oscillator A (the primary oscillator) uses an ’endless’ clickable encoder to set its base fre- quency. -
Page 6: Osc A Pd Algorithm
4.5 OSC A PD Algorithm The ’PD Algo’ control morphs continuously through 9 different phase distortion ’algorithms’ (i.e lookup table distortion types) of varying complexity that determine the character of ’Shape’ control’s timbral sweep. The PD Algorithm is set by the offset and associated PD/A CV input. 4.6 OSC B Shape Control OSC B produces the classic CZ style resonance waveform intended for creating pseudo reso- nant filter sweeps. -
Page 7: Osc A And B Level Controls
4.8 OSC A and B Level Controls Each oscillator’s output is routed through a dedicated digital VCA with manual level control and CV input. When CV is inserted the associated level control functions as an attenuator for the CV. 4.9 Chord Controls OSC A and B are each able to produce 4 voice chords simultaneously, with their fundamental frequencies setting the root note of the selected chord. -
Page 8: Patch Examples
5 PATCH EXAMPLES 5.1 Stereo ’Reese’ Bass Voice 1. Engage the Mix switch and increase both Level controls. 2. Engage the OSC B Track switch and detune its frequency +/- 1 semitone from OSC A. 3. Patch a pitch CV to the OSC A V/Oct input and mult an envelope to both Level CV inputs. 4. -
Page 9: Ring Modulated Chords
5.2 Ring Modulated Chords 1. Increase the OSC B Level control and set the mode switch to ’Ring’ . 2. Engage the OSC B Track switch and adjust its frequency to taste, emphasising different harmonics in the ring mod. 3. Select a chord with the Chord control. 4. -
Page 10: Dual Synth Voices
5.3 Dual Synth Voices 1. Increase both Level controls and tune the two oscillators to the same fundamental fre- quency. 2. Patch the first pitch CV to the OSC A V/Oct input and the second to the OSC B Pitch input (V/Oct). -

Page 12: Appendix
8 Appendix 8.1 Firmware update With the unit unpowered, connect a USB cable from the port at the left side of the PCB (near the PD Algo knob) to a computer. The CIZZLE will appear as a standard removable storage device. -
Page 13: Vcv Rack Version
8.3 III. VCV Rack Version ’VCV Rack’ is an open-source cross-platform software based virtual modular environment. A fully featured emulation of the CIZZLE is now available for purchase via the VCV Rack store: https://library.vcvrack.com/ALM042/ The emulation runs identical core code and has the same user interface as the physical mod- ule.
