The world’s first music equalizer is now playable
Scaler EQ Pro is an advanced version of the award-winning Scaler equalizer with note support. Scaler EQ Pro brings musical intelligence to every stage of mixing, mastering, and sound design. Shape frequencies according to notes, scales, and harmonies, dynamically control low and high frequencies , and even play the EQ via MIDI—all while maintaining the musical context at the core of your sound.
Built on Scaler’s patented note-based equalization technology and enhanced with all-new filtering technology, Scaler EQ Pro delivers smoother, more natural harmonic peak filtering, seamless slope control, dedicated low- and high-frequency compression, continuous gain matching, and a new MIDI-controlled Live mode.
What can Scaler EQ Pro be used for?
Music Creation
Ideal for musicians and producers who want to make their tracks more melodic, achieving harmony between all instruments and the chosen key.
Audio Editing
Simplify the equalization process by adjusting and cleaning up frequency ranges to remove unnecessary sounds and enhance those that naturally harmonize with the chosen key.
Sound Design
Transform virtually any recorded sound into a fully-fledged musical instrument. Enhance resonant frequencies in a key to transform textures into musical pads, add expressiveness to drum parts, or use MIDI notes and chords to bring specific harmonics to life.
Mastering
Place on the master channel to widen the stereo image, focus the bass, increase volume and improve the mix.
Key Features
Music EQ
- Patented key-aware music EQ boosts frequencies that match the key and scale, or cuts frequencies that fall outside them.
- An all-new music filter engine delivers smoother, more natural, and accurate key-aware processing.
- Redesigned Harmonic Peak filters precisely tune to musical frequencies, smoothly transitioning into adjacent notes.
- Automatic key detection analyzes your music and adapts the EQ to the key and scale.
- Three scale slots let you switch between different keys and scales within a single project.
- Edit individual notes within a scale to fine-tune harmonic processing.
Precision Filtering
- Smoothly variable filter gains transition seamlessly from standard values to fixed steps.
- Traditional and musical EQ bands combine familiar precision EQ with Scaler’s tonality-aware processing.
- Tilt, Notch, Peak, Shelf, High/Low Cut, and band-pass filters provide a complete set of modern EQ tools.
- Magic Shelf shapes the low and high frequencies by intelligently processing stereo information.
- Minimal phase and no latency make Scaler EQ Pro suitable for mixing, tracking, and live use.
Dynamics and Mastering
- Dedicated low-pass compressor controls low-end energy while maintaining richness.
- Dedicated high-pass compressor smooths out harsh high frequencies while preserving detail.
- Dynamic EQ on any frequency band with threshold, ratio, attack, and release controls.
- Mid and side processing on each frequency band provides precise control of the stereo, mid, and side frequencies.
- Dynamics with sidechain control allows external signals to drive individual frequency bands.
- Continuous Gain Match compensates for level changes, letting you judge processing quality rather than loudness. • Stereo width and mono low-pass controls help shape spatial balance and focus the low frequencies. • Input and output peak limiters provide level protection.
Live Mode
- MIDI-controlled Live mode lets you boost or cut frequencies by playing MIDI notes.
- Polyphonic mode lets you play multiple MIDI notes or chords simultaneously, creating multiple musical frequency bands.
- Velocity sensitivity adjusts the degree to which each played note affects the EQ.
- The ADSR function determines how the processing changes over time.
- Performance Solo mode turns the EQ into an effect that can be used during performance.
- Live Band Solo mode isolates the frequencies being processed at any given moment.
Workflow and Sound Design
- Transform recorded audio into musical material with scale- and harmonic-resonance-aware filtering.
- Hundreds of presets for mastering, instrumentation, mixing, and sound design.
- Mid/Side processing in each frequency band provides precise control over stereo, mid, and side information.
- Input/output level controls with peak and RMS meters simplify gain adjustment and monitoring.
- A completely redesigned interface and workflow combine an expanded toolset into a faster workflow.
- Patented in the United States (US Patent No. 12,647,085) for Scaler’s note-aware audio processing technology.
