Reason Studios Complex-1 | Eurorack-style patchable modular synthesizer, ideal for experimental tones and modern electronic sound design
Complex-1 is a modular synthesizer Rack Extension from Reason Studios that brings the patchable workflow of classic Eurorack to the Reason Rack. It combines analog-style oscillators and filters, utility modules, and flexible control-voltage routing—capable of everything from warm retro tones to avant-garde experimental sounds. Built-in presets are ready to play, and you can dive deeper with virtual patching to craft unique dynamics and textures.
Key Features
- Eurorack-inspired fully modular design: freely patch with virtual cables to create custom signal and modulation flows.
- Sound engine blending analog and digital elements: a variety of oscillators, noise, filters and shaping modules covering tones from fat to granular.
- Flexible modulation system: envelopes, LFOs, random/sample-and-hold and utility modules, supporting advanced techniques like audio-rate modulation, FM/AM.
- Semi-modular experience: preset internal normalized routing lets you make sound without patching, while further wiring allows full customization.
- Extensive preset library: from basses and leads to textured pads and effect sounds—explore Complex-1's broad sonic range with one click.
- Full CV interoperability: two-way CV/audio exchange with other Reason devices for building large composite sound systems.
- DAW-synced modulation: LFOs and tempo-related modulation sync easily to the beat—ideal for pulsing rhythms and dynamic sequences.
- Detailed parameter automation: all key knobs and switches can be automated for easy mixing and live performance.
System Specifications
- Platform: Reason Rack Extension (requires a compatible version of Reason or the Reason Rack Plugin).
- Operating systems: macOS, Windows (actual versions and hardware requirements follow Reason/Reason Rack Plugin specifications).
- Authorization: Requires a Reason Studios account; initial activation/authorization may require an internet connection.
- Access: Load from the Reason browser or the device list in the Rack; supports project automation and preset management.
Plugin Formats
- Rack Extension (RE) device format.
- Can be used indirectly in compatible DAWs via the Reason Rack Plugin as VST3/AU (and AAX where available on the platform).
Supported Applications and Main Workflow Integration
Complex-1 runs natively in the Reason DAW and can be deeply interconnected with other Rack devices via audio and CV; all parameters can be automated by the DAW, MIDI-mapped, and tempo-synced. When used in third-party DAWs, place Complex-1 inside the Reason Rack Plugin to integrate workflows, including preset management, Combinator encapsulation, sidechaining and multitrack routing—suitable for cross-platform integration in production, performance, and sound design.
