Scaler 3 for iPad
Drag and drop chords to build a progression. Choose from hundreds of chord sets — categorised by artist, genre, or mood — and Scaler will show you which parent scales fit. Stuck for ideas? Ask Scaler to suggest chords that will work next.
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.
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.
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.
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.
Solve your modulation puzzles with Scaler’s suggested pathways. Choose a destination scale and Scaler will offer multiple ways to reach it. You’ll also find Modal Interchange, Mediant and Neo-Riemannian modulation methods here too. Use the Circle of Fifths to explore related chord substitutions and variations that expand your harmonic options.
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.
Create evolving arrangements with Scenes. Build, duplicate, and arrange chord variations or sections to structure full tracks quickly and intuitively. Perform each Scene independently to explore different ideas or arrange full arrangements.
Record melodies, chords, and ideas directly into Scaler’s piano roll. Capture chord triggers or Keys Lock performances and refine them with full MIDI editing and harmonic guides.
Control how chord voices are split across instruments with full Divisi and voice allocation, sending upper and lower notes to separate Scaler instances for realistic ensemble writing and richer layering. The Bass Follow Track automatically generates basslines that follow the root of your chord track.
Scaler 3 for iPad hosts AUv3 plugins, lets you build full arrangements, and works seamlessly with your favourite iPad music apps. Create on iPad, then bring your ideas into Scaler 3 on desktop. Available separately on the App Store.
