About
Scaler 2 is a powerful music theory workstation plugin developed by Scaler Music, designed to empower music producers and composers regardless of their theory background. At its core, Scaler 2 detects keys, scales, and chords from audio or MIDI input and helps users build in-key chord progressions with ease. It offers a massive library of scales and voicings, smooth workflow for exploring harmonic possibilities, and intelligent suggestions that make composition intuitive and creative. Used by globally recognized artists like Carl Cox and Jean-Michel Jarre, Scaler 2 has become an essential tool in modern music production. The Scaler Music ecosystem extends beyond Scaler 2 with Scaler 3 — the most advanced version, featuring a fully integrated composition workstation — as well as Scaler EQ, the first truly musical equalizer that emphasizes in-key frequencies for harmonically aware mixing, and DC Snares, a flexible drum construction kit. Scaler is available on both desktop DAW environments (Windows and macOS) and mobile (iPad via the App Store), making it accessible in studio and on-the-go workflows. Whether you're a beginner looking to understand harmony or a seasoned producer wanting to compose faster, Scaler 2 provides the tools to unlock creativity and craft professional-sounding music with confidence.
Key Features

- Massive Scale & Voicing Library: Includes a huge variety of scales, modes, and chord voicings from across musical genres and traditions, giving composers endless harmonic options.
- Harmonic EQ (Scaler EQ): Scaler EQ emphasizes in-key frequencies to make mixes sound more musical and tonally coherent — the first EQ designed with music theory in mind.

Use Cases
- Music producers building chord progressions quickly within a specific key or scale for tracks across genres like EDM, pop, hip-hop, and jazz.

- Beginner musicians learning music theory concepts such as scales, modes, and chord relationships in an interactive, hands-on environment.
- Professional mixing engineers using Scaler EQ to apply harmonic-aware EQ that emphasizes in-key frequencies for more musical-sounding mixes.
- iPad-based producers creating chord-driven music on the go using Scaler 3's native mobile app without needing a full desktop DAW setup.
Pros
- Accessible to All Skill Levels: Designed to be intuitive for beginners while offering deep harmonic exploration for advanced composers, making it genuinely useful across skill levels.
- Industry-Recognized Quality: Multiple prestigious music technology awards and endorsements from world-class artists like Carl Cox and Jean-Michel Jarre validate its professional-grade output.
- Comprehensive Ecosystem: The Scaler Music suite (Scaler 2/3, Scaler EQ, DC Snares, Carbon Electra) covers chord generation, harmonic EQ, drums, and synthesis in one cohesive product family.
Cons
- Paid Software Only: Scaler 2 and the broader Scaler Music suite are premium paid products with no free tier, which may be a barrier for hobbyist producers on a tight budget.
- Focused on Harmony: While excellent for chord-based and harmonic composition, Scaler 2 is less suited for rhythmic, sound-design, or mixing-centric workflows.
- Requires DAW Integration: As a plugin, Scaler 2 works within a host DAW environment, meaning standalone use on desktop requires additional software setup.
