Scaler: music composition plugin updated to v3

PluginAlliance / ScalerMusic has released an updated version of its music theory/composition plugin Scaler.

If you've ever felt creatively blocked when writing chords or melodies, Scaler has likely been on your radar. Now, with the release of Scaler 3, this innovative music theory plugin has been completely re-imagined and powered up, offering a wealth of new features designed to make music production more intuitive and inspiring. This article provides a comprehensive overview of what's new in Scaler 3 and why it could be a game-changer for your music creation process.

What is Scaler 3?

At its core, Scaler 3 is a plugin that helps you find chords, create progressions, and even come up with melodies and basslines without requiring in-depth music theory knowledge. It listens to your MIDI input or detects the key you're working in and suggests musical ideas that you can instantly use in your Digital Audio Workstation (DAW). You can begin with chord sets crafted by real artists or build your own progressions. Scaler 3 then allows you to trigger these chords via your MIDI keyboard or by clicking to audition and dragging them as MIDI directly into your DAW.

A Brand New User Interface for Enhanced Workflow

One of the most immediate changes in Scaler 3 is its redesigned user interface (UX/UI). The new interface is organized into three main pages: Browse, Create, and Arrange. Sanjay C notes that the previous version had many features hidden under menus, which is no longer the case.

• Browse Page: This is where you explore scales and chord sets. Section A allows you to browse progressions, either by genre or artist, and even detect MIDI or audio input to get started. Section B displays the scale you're currently in, offering a space for exploration for those familiar with music theory. Section C, the main track, is where you build your chord progression by dragging and dropping chords. The panels are now resizable for a more personalized workflow.

• Create Page: This section offers a variety of compositional tools to help you discover and develop chords, explore harmonic relationships, and refine your progressions. New tools like Explore, Colors, and Sketch have been added alongside the familiar Circle of Fifths and Modulation pages.

• Arrange Page: This is where you can build full arrangements by adding independent tracks for chords, melodies, basslines, and phrases, all synchronized with your main chord progression.

The Power of the Arrange Page: A Full Creative Engine

Scaler 3 transforms into a full creative engine with its new multitrack arranger within the Arrange Page. This is a significant upgrade from Scaler 2, allowing you to sketch out entire song ideas within the plugin itself.

• Independent Lanes: The Arrange page features a timeline-based layout with dedicated lanes for chords, melody, bass, and phrases. Each lane operates independently but remains synchronized with the main chord track.

• VST/AU Hosting: A headline feature is the ability to load your favorite third-party instrument and effect plugins directly onto Chord Tracks and MIDI Lanes. This eliminates the need for complex MIDI routing and allows for seamless integration of your existing sound libraries. You can browse your plugins by manufacturer or mark them as favorites for quick access.

• Motions: Scaler 3 reimagines Phrases, Performances, Melodies, and Basslines from previous versions as Motions. These pre-recorded performances, crafted by professional musicians, now include mood-based tags for easier browsing. The library has been significantly expanded with hundreds of new Motions, including the all-new Passages Motion. You can customize these Motions using a piano roll interface or create your own from scratch.

• Note Editing & Harmonic Modifiers: A comprehensive note editing matrix allows for customization of Motions. MIDI lanes can follow the Chord Tracks or run independently, with new Harmonic Modifiers and Motion Controls to adjust note range, density, pitch, and clip rotation within the chosen scale.

Explore New Sonic Territories with the Create Page

The Create Page introduces powerful new tools to push your harmonic boundaries:

• Explore Page: This page offers a Harmonic Universe of chords untied to any specific scale. Categorized by genre and feel (Dark, Bright, Neutral), it suggests compatible and experimental chord progressions, helping you break free from predictable chord choices and discover unique harmonic structures. The Dynamic Scale feature automatically adjusts chord colors based on the last played chord, while Fixed Scale mode keeps them consistent with the Current Scale.

• Colors Page: This page provides a comprehensive view of all chord voicings and harmonic alternatives in a single, unified interface. You can instantly access parallel and relative chords, as well as diverse voicing and substitution options, to add expressivity and creative flexibility to your compositions.

• Sketch Page: This sandbox-style tool allows you to test out alternate chord progression ideas before committing them to the timeline. You can build up to seven different progressions, audition them with various voicings and motions, and then drag the ones you like into your arrangement. It also features a unique Suggest Mode for generating new chord progressions.

Enhanced Features and Workflow Improvements

Scaler 3 boasts several other enhancements that contribute to a more fluid and powerful music creation experience:

• Standalone App: Scaler 3 can now run as a standalone application for both Mac and Windows in addition to being a plugin. This offers a complete and flexible songwriting tool with multitrack operation and plugin hosting, even without a DAW.

• Expanded Content: Scaler 3 includes a significant expansion of content, with more Chord Sets, Harmonic Universes, Motions, and Scales contributed by Samplify Studio and top-tier artists. There are now 860 chord sets and 929 Motions to choose from.

• Enhanced Categorisation: Improved filtering and search functionality enable quick navigation across Scaler 3’s extensive content. You can search by mood, energy, note count, scale, and more.

• Enhanced Internal Sound Engine: The internal sound engine now includes ADSR and Filter control, effects, and multi-layered sounds for deeper sound customization. While the internal sounds are improved, the ability to host third-party instruments remains a major highlight.

• Improved Strumming, Arpeggios & Quantisation: Easily adjust note lengths, quantisation, density, swing, and other parameters for strumming and arpeggios to achieve a more personalized rhythm.

• Refined File Management: Effortlessly save, share, and manage audio files, songs, and chords, with the ability to tag favorites across Motions, Chord Sets, and Harmonic Universes.

• Advanced Keys Lock: The full keyboard is now available for Keys Lock profiles, allowing basslines and melodies to align perfectly with scale and chord structures. The new Chord Scale profile dynamically detects chords and adjusts locked notes to fit the appropriate scale or mode.

• New Auto Voice Leading & Improved Voice Grouping: Select multiple chords to apply seamless voice leading automatically. Voice Grouping can now be applied to individual chord clips or even to individual notes.

• Templates: New pre-made session setups include chord progressions, instruments, and motion clips across multiple tracks, providing a quick starting point for beginners and advanced users alike.
