Korg ARP ODYSSEY Module Rev1 Analog Synthesizer

Korg ARP ODYSSEY Module Rev1 Analog Synthesizer

The Korg ARP ODYSSEY Module Rev1 is a compact, keyboard-less analog synthesizer module that faithfully recreates the circuitry and sonic character of the original ARP Odyssey (Rev1/early white panel design). Designed for studio producers, modular users, and electronic musicians, it delivers authentic duophonic analog synthesis in a streamlined desktop format optimized for modern DAW and hardware hybrid setups.

Unlike keyboard versions, the Module Rev1 is built for integration into external control environments via MIDI, USB, CV/Gate, and trigger connections, making it a flexible sound engine for both vintage-inspired synthesis and modular workflows.

True Analog Duophonic Synthesis

The ARP ODYSSEY Module Rev1 features a fully analog signal path based on the original ARP Odyssey architecture. It supports duophonic play, allowing two notes to be played simultaneously with independent oscillator behavior while sharing a single filter and amplifier stage.

• Fully analog VCO, VCF, and VCA signal path
• Duophonic operation (2-note capability)
• Monophonic mode with classic ARP response
• Faithful recreation of original ARP circuitry

Rev1 Filter Character (12 dB/octave Type I)

The Rev1 version is known for its distinctive filter response, delivering a sharper, more aggressive tone compared to later revisions. It is especially suited for cutting leads, punchy basslines, and expressive modulation work.

• Filter Type I (Rev1) emulation
• 12 dB/octave low-pass filter
• Strong resonance behavior with self-oscillation capability
• Classic bright and biting ARP tonal character

Dual VCO Architecture with Hard Sync

The synthesizer uses two voltage-controlled oscillators (VCOs), allowing rich detuning, sync tones, and complex harmonic interaction. This architecture is central to the signature ARP sound.

• Two analog VCOs
• Saw, square, and pulse waveforms
• Oscillator sync for aggressive harmonic shaping
• Wide frequency range for bass to high-frequency leads

Flexible Modulation System

A wide modulation system allows deep sound design through LFO, sample & hold, envelope generators, and noise sources. This makes the module highly versatile for evolving textures and experimental synthesis.

• LFO with multiple waveform options
• Sample & Hold for random modulation effects
• ADSR and AR envelope generators
• White and pink noise generator

Classic Performance Controls

The original ARP Proportional Pitch Control (PPC) system is recreated in the module, providing expressive pitch and modulation control through pressure-sensitive pads rather than traditional wheels.

• Proportional Pitch Control (PPC) pads
• Transpose control (±2 octaves)
• Portamento with wide time range
• Hands-on performance-focused interface

External Control and Integration

The ARP ODYSSEY Module Rev1 is designed for modern setups, offering full integration with MIDI, USB, and analog CV/Gate systems for modular and hybrid studio environments.

• MIDI IN support
• USB Type-B connection for DAW integration
• CV IN/OUT (1V/oct standard)
• Gate and Trigger I/O for modular synchronization
• External audio input for processing external signals

Audio Output Options

The module provides both low-level and professional high-level outputs, making it suitable for a wide range of studio and live sound systems.

• Low output (instrument level)
• High output (XLR balanced, +4 dBu)
• Headphone output with dedicated volume control
• External audio input for filtering and processing

Compact Desktop Form Factor

The Rev1 module removes the keyboard while retaining full synthesis functionality, offering a compact footprint that fits easily into studio racks, desktop setups, and modular systems.

• Keyboard-less desktop module design
• Approx. 496 × 265 × 89 mm
• Lightweight and portable at ~3.7 kg
• Optimized for DAW and modular integration
