Reason Studio Arpeggio Lab | Creative Arpeggio Design and Rhythm Generator
Reason Studio Arpeggio Lab is an arpeggio and rhythm tool designed for composing and performing, able to quickly turn chords or single notes into rhythmically engaging melodic fragments. With common arpeggio directions, scale locking, Gate and Swing controls, you can easily create multi-layered rhythms and variations — ideal for electronic music, scoring, and live improvisation.
Key Product Features
- Multiple arpeggio directions and playback logics (such as Up, Down, Up-Down, As Played, Random) to quickly suit different styles.
- Adjustable octave range, step length, and rate to finely shape density and energy.
- Gate, Swing/Shuffle, and accent controls for more expressive rhythmic feel.
- Scale/mode locking and chord-directed transposition to reduce out-of-key notes while preserving harmonic context.
- Rhythmic subdivisions and syncopation variations to easily create multi-layered grooves and complex rhythmic feels.
- Variation and randomization parameters to generate new material and sparks of inspiration within safe ranges.
- MIDI output can be sent to downstream instruments and recorded in the DAW for further editing and refinement.
- Supports automation and controller mapping (depending on host), useful for live performance and detailed arrangement.
- Custom presets can be created and saved (depending on host support) to speed up common workflows.
System Requirements
- Operating system: Windows 64-bit, macOS (supports Apple silicon and Intel).

- Recommended: 8 GB RAM or more, available storage; installation and authorization may require an internet connection.
- Optional: MIDI keyboard/controller to enhance playing and real-time control experience.

- Use in DAWs via Reason Rack Plugin: VST3, AU, AAX (actual available formats depend on host and version).
Supported Applications and Workflow Integration
In Reason, place Arpeggio Lab as a Player before an instrument; incoming MIDI will be arpeggiated and sent to the target sound. It can work with the DAW's tempo, time signature, and automation, and the output can be recorded to a MIDI track for further editing. In other DAWs, load it via the Reason Rack Plugin and insert Arpeggio Lab in the Rack, routing it to instruments inside the Rack or to external sound sources — enabling workflows in Ableton Live, Logic Pro, Studio One, Cubase, Pro Tools, and more. It can also be used with workflow tools or AI assistants that provide chord progressions and rhythm suggestions, allowing quick parameter tweaks to produce usable musical phrases.
