- Page 4 Architecture Pizza Oscillator architecture is centered around 3 oscillators: MAIN, OCT, and RATIO. The core of the module is digital FM (phase) modulation, where the MAIN oscillator is the carrier while OCT and RATIO are the modulators. Both OCT and RATIO can be WAVE-shaped (SQUARE-SINE-SAW) before applied to the FM.

- Page 7 Power Before connecting the ribbon cable to this module, disconnect your system from power! Double-check the polarity of the ribbon cable and that it is not misaligned in any direction. The red wire should match the -12V rail both on the module and the bus board. ! please make sure of the following ●...
- Page 8 PITCH and TUNE The PITCH knob and button give access to all tuning-related duties and will prevent you from accidentally detuning your oscillator. OCTAVE and DETUNE A single press of the PITCH button will switch between OCTAVE mode and DETUNE mode. In OCTAVE mode, the PITCH knob adjusts the octave (+/-4 octaves).
- Page 9 2 – FM INDEX fader FM INDEX is the depth of frequency modulation (phase modulation, in fact) applied to the MAIN oscillator (carrier). In the middle position, no modulation is applied, and when no other waveshaping is applied, you should hear a sine-wave at the MAIN output. When moving FM INDEX to the left, the RATIO oscillator modulation is applied.
- Page 10 (range 1-16). Switch between setting the numerator and denominator by short pressing the PITCH button. When turning the PITCH knob, the TUNE led will blink each time the value changes, so it can help you to count specific number ratios. Long-press the RATIO OSC button to leave the RATIO SETTING mode.
- Page 11 SHAPE 7 – SHAPE fader and SHAPE CV (-6V to +6V) Similar to the FM modulation section, the waveshaper slider is neutral in the middle with two different modes on the left and right sides of the slider. It’s possible to use two shapers simultaneously by assigning the CTRL to one of the shape modes.
- Page 12 Ranges of both folding algorithms can be extended via CV or by assigning the CTRL knob to FOLD. Note: The fundamental frequency will be weakened by such a process, which will result in less bass in your signal. This issue is commonly addressed by mixing the oscillator outputs together.
- Page 13 CTRL 11 – CTRL knob and CTRL CV (-6V to +6V) The CTRL is an assignable control. The CTRL knob can serve as a static control or, when you plug voltage into the CTRL CV input, as an attenuverter. To enter ASSIGNMENT mode, hold the SHAPE button for a few seconds. The currently assigned CTRL destination will start blinking.
- Page 14 V/OCT input serves as external control of the oscillator’s pitch. It includes several features to keep you in tune. The main struggle in modular synthesis is to match your V/OCT source and your oscillator. Pizza has you covered with the V/OCT CALIBRATION MODE.
- Page 15 Press the OCT OSC button to learn what 0V means. 2 starts blinking = apply 2V on your V/OCT source (play a note that’s two octaves higher =2V). Press OCT OSC button to learn what 2V means and Pizza will return to V/OCT CALIBRATION MODE.

Page 18: Firmware Update
Disconnect the USB and install Pizza in your rack Pizza shows the firmware version by a static light of the LEDs at startup. The first beta firmware has the TUNE light ON. V1.0 has G/H light ON. -
Page 19: Tips And Tricks
Connect MAIN and OCT OSC outputs to an oscilloscope in XY mode. Connect static voltage to EXT input and observe how phase relationships distort the image. While playing melodies on Pizza, go to CTRL assignment mode and switch between OCTAVE, RATIO OSC, and OCT OSC to get various flavors of arpeggiation. - Page 20 Beta Testers David Žáček, Milan Říha, John Dinger, Václav Mach, Peter Edwards, Oliver Torr, Patrik Veltruský, Niels Aras, David Herzig, Leo Hivert Management John Dinger Graphic design Anymade Studio The idea turned into reality thanks to everyone at Bastl Instruments and thanks to the immense support of our fans.
