Build Progressions

Drag and drop chords to build a progression. Choose from hundreds of chord sets categorised by artist and mood, and Scaler will be able to tell you which parent scales fit well with those chords. Stuck for ideas? Ask Scaler to suggest chords that will work next.

VST/AU Hosting

Load your favourite third-party instrument and effect plugins directly onto Chord Tracks and MIDI Lanes, with full support for both MIDI and audio effects. Seamlessly integrate your sounds and expand Scaler 3's creative potential within your workflow.

Multi-Lane Timeline

The Arrange page now includes a timeline-based layout with dedicated lanes for chords, melody, bass, and phrases. Each lane is synchronized with the main chord track, and clips are fully adjustable with independent control per lane or clip.

Standalone App

Scaler 3 can now run as a standalone app for Mac and Windows in addition to a plugin within any DAW, offering a complete and flexible songwriting tool with multitrack operation and plugin hosting.

Explore Page

Discover a Harmonic Universe of chords untied to any specific scale. Categorized by genre and feel (EG, Dark, Bright, Neutral), the Explore page suggests compatible and experimental chord progressions, unlocking new paths for unique and bold harmonic structures.

Colors Page

Explore a comprehensive view of all chord voicings and harmonic alternatives in a single, unified page. Instantly access parallel and relative chords, as well as diverse voicing and substitution options, to add expressivity and creative flexibility to your compositions.

Motions

Scaler's beloved Phrases, Performances, Melodies, and Basslines are reimagined as Motions, now with mood-based tags for easier browsing. Scaler 3 introduces hundreds of new Motions crafted by professional musicians, including the all-new Passages Motion.

Circle of Fifths

Get alternative chords for your progression. Choose a root note that's closer or further from your selected chord, or in a relative minor or major scale, and you'll see which variations of that chord fit with your current scale in blue. You can experiment with chord inversions and transpositions here too.

Modulation Pathways

Solve your modulation puzzles with Scaler’s suggestions. From your current progression, choose a destination scale and the software will suggest multiple ways to reach it. You’ll also find Secondary Scale, Modal Interchange, Mediant and Neo-Riemannian modulation methods here, too.

Note Editing & Harmonic Modifiers

A comprehensive note editing matrix allows users to customize or create new Motions. MIDI lanes can be set to follow or run independently of Chord Tracks, with new Harmonic Modifiers and Motion Controls to adjust note range, density, pitch, and clip rotation – all within the chosen scale.

Features

• Access over 1,000 chord sets, keys, and modes, categorized by mood, artist, and genre.

The World's First Truly Musical EQ

ollowing on from the award-winning Scaler music theory plugin, Scaler EQ offers a remarkable new way to EQ with musicality and colour.

By enhancing only note frequencies in key with your song, and reducing only note frequencies that aren’t, Scaler EQ can provide a new spin on working with cuts and boosts, increasing the tonality behind your music and providing new harmonic avenues.

And for when you just want a regular, fully-featured, modern EQ, Scaler EQ has you covered with its familiar workflow, large choice of band types, mid/side operation, dynamic bands, peak limiters, and stereo enhancement. You can easily apply classic mixing and mastering techniques used by professionals, with an extra optional musical edge.

What can Scaler EQ be used for?

• Music Production: Ideal for musicians and producers looking to enhance the musicality of their tracks by ensuring all instruments are in harmony with the chosen scale.
• Audio Editing: Simplify EQ processes by targeting and cleaning up frequency bands to remove audio that doesn’t belong and enhance audio naturally present with the chosen scale.
• Audio Engineering: Dynamically soothe audio by suppressing in-harmonic frequencies or expanding harmonic frequencies using dynamic compression and expansion.
• Mastering: Place on your master channel to broaden your stereo width, focus your bass, increase loudness, and enhance your mix.
• DJing: DJs can use it to ensure that the tracks they mix are in harmony by detecting the key and scale whilst balancing the mix of each track.

The World’s First In-Key EQ

Thanks to its Harmonic Peak and ‘Plus/Minus’ filter types, performing a boost on Scaler EQ means only boosting frequencies that are in-key with the currently set scale. Making a cut with the same band will reduce only the out-of-key frequencies – although it can be set to cut in-key frequencies too, which can be helpful for mixing.

By using in-key EQ, you’ll get warmer lows and sweeter highs when boosting, while out-of-key cuts will lead to clearer, more focused bass and less harsh highs that retain their musicality.
