The legendary SID chip reimagined as an expandable modular synth voice: powerful synthesis engine, animated OLED display, and phybus-ready for seamless multi-unit expansion.
zetaSID is a powerful eurorack modular synthesizer voice packed into just 4 HP, expandable via midiphy phybus. Start with a single monophonic voice controlled via CV/gate and scale it to a full polyphonic MIDI synthesizer with up to six stereo voices with MIDI control. At its core lies the MIDIbox SID synthesis engine, featuring six LFOs, dual envelopes, quad wave sequencers, eight modulation paths with dozens of sources, algorithmic operations, and an extensive trigger matrix.

One of the world's most powerful SID sound engines: based on MIDIbox SID, offering six LFOs, eight modulation paths, two envelopes (with delay, multi-stage attack, decay, and release phases, plus envelope curve shape control), four integrated wave sequencers to animate patch sound progression over time, three independent oscillator arpeggiators, and a powerful 24x14 event trigger matrix for vast sound design options within the Lead sound engine.

The Bassline engine is optimized for 303-style sounds and boasts a stereo-linked sequencer with eight patterns, 16 steps with gate, slide, accent and extra parameter controls for classic acid style sounds.

Alternatively, the Drum sound engine with up to 16 different parallel instruments per zetaSID is available. Percussive sounds can be created from 19 parametric drum algorithms, ranging from bass drums to toms, snares, claps, and classic C64 sound effects, capturing the joy and fun of percussion sounds from that era.

Rack-space-saving 4HP minimalism with an intuitive graphical UI featuring fluid visualization of oscillator outputs, arpeggio patterns, filter curves, and more.

Integrated ROM bank with 100 great-sounding preset patches.

State-of-the-art SID sound chip emulation for noise-free sounds faithful to the original chip output from the 1980s.

Stereo sound engine design: link two zetaSIDs via phybus for a true stereo instrument voice. Most patches take advantage of the engine's stereo capabilities.

Stereo voice polychaining: chain up to twelve zetaSID modules in a phybus instrument cluster for six polyphonic stereo voices.

Multi-SID unison mode: link multiple zetaSIDs and individually detune them for an incredibly fat unison sound.

User interface expansion: use phybus UI cooperation to adjust different sections of the same patch on multiple zetaSIDs simultaneously, e.g. work on filter, oscillators, and LFOs on different modules at the same time.

Integrated advanced per-oscillator arpeggiators with individually configurable and syncable clock speeds and powerful arpeggio parameters for classic chiptune sounds: from slow arp sequences to high-speed multi-octave performances.

Integrated quad wave sequencer: based on an original C64 sound generation technique called "wavetables" (unrelated to modern wavetable synthesis), this allows step-wise modulation of SID patch parameters with a multitude of options, e.g. fine-grained adjustments of oscillator pitches over time using absolute or relative sequencer values for each step. Four wave sequencers per patch with individually configurable playback speeds are available.
