Bastl Instruments Pizza Modulärt system

Bastl Instruments Pizza – Digital Complex Oscillator for Sonic Exploration

The Bastl Instruments Pizza complex oscillator module brings advanced FM and dynamic waveshaping to Eurorack systems in just 8 HP. Designed for creators seeking instant access to rich timbres, the module combines three digital oscillators with flexible modulation and assignable controls. Pizza’s unique interface makes FM synthesis approachable while offering deep creative potential. The module’s blend of intuitive hands-on controls, assignable modulation, and hybrid synthesis techniques positions it as a top choice for adventurous sound designers. The Bastl Pizza delivers a vast palette of harmonic, gritty, and musical tones—ideal for both experimental and traditional modular patches.

Three-Oscillator FM Engine and Assignable Control

What makes the Pizza unique is its internal triple-oscillator core: a main oscillator, octave (sub) oscillator, and ratio oscillator—each with independent waveshaping. Players can crossfade FM sources, engage ring modulation, and manipulate timbre using dedicated sliders and the assignable CTRL knob. These features provide hands-on access to linear and exponential FM, oscillator ratios, wave folding, and even built-in VCA or envelope modulation, all from a compact front panel.

Flexible Output Architecture and Patch Integration

Integration into any Eurorack setup is simple thanks to the Pizza’s three distinct outputs—main, pulse, and sub/octave—plus direct phase modulation via EXT input. The module includes easy V/OCT calibration and quantization, enabling seamless pitch tracking and compatibility. Firmware updates by micro-USB and a sync input for resetting oscillators expand integration options further.

• Width: 8 HP — fits compact and dense modular systems.
• Depth: 24 mm — shallow enough for skiff cases.
• Designed for efficient power usage in multi-module setups, current draw is +12V: 90 mA, -12V: 20 mA.

Advanced Waveshaping and Hybrid Synthesis Tools

This module delivers a rare combination of additive (via waveshaping on the main output) and subtractive (using pulse and sub outputs through filters) techniques. Two flavors of wavefolding, ring modulation, and user-definable oscillator ratios add further depth. The SHAPE section lets you morph between square, sine, and saw waves, with crossfading FM index modulation unlocking metallic, bell-like, and evolving tones—ideal for experimental, melodic, or percussive roles.

• Main Oscillator: Phase modulation (FM), wavefolding, ring modulation — rich, complex core sounds.
• With its dedicated output and morphing between square, sine, and saw, the octave oscillator supports both bass and layering duties in a modular environment.
• Ratio Oscillator: User-adjustable ratios, ring mod, waveshaping — advanced FM color and harmonics.

Hands-On Performance and Creative Playability

For live performers and studio experimenters, Pizza’s control layout encourages deep hands-on exploration. The unique shape slider, assignable CTRL/CV, and FM index crossfader facilitate fast tone changes and instant access to sweet spots—making even complex FM easy to control. With automatic tuning, octave and detune adjustments, and user-assignable parameters, the module rewards real-time manipulation.

• Assignable control for FM, ratios, octave, detune, waveshaping, envelope, or VCA—tailor for any patch.
• Sync and EXT inputs expand modulation and integration potential.
• Front-panel calibration and tuning streamline workflow for studio and stage.

Who Is It For – Modular Sound Designers & Experimental Musicians

Designed for modular enthusiasts, experimental musicians, and those seeking a versatile digital oscillator, this model excels in both melodic and abstract roles. The Bastl Instruments Pizza is the right choice for creators who need instant access to hybrid FM textures, complex timbres, and hands-on modulation in a compact package. Whether used as a bass voice, bell source, drone generator, or gritty lead, this instrument adapts to evolving creative demands. Sound designers, live performers, and producers who value morphing digital tones and an intuitive interface will find the Pizza an inspiring addition to any Eurorack rack.
