Scaler EQ Pro Upgrade: Note-Aware EQ Plugin by Scaler Music

The core of the plugin is note-aware EQ. It boosts frequencies that belong to your key and scale and can reduce those that fall outside them. Automatic key detection analyzes the material and adapts the EQ to the detected key and scale, and three scale slots let you switch between keys within one project. Individual scale notes can be edited to fine-tune which harmonics are processed.

The filter section includes Tilt, Notch, Peak, Shelf, High/Low Cut and Band-Pass filters. Continuously variable slopes move smoothly between conventional values, and Magic Shelf filtering shapes the low and high end while managing stereo information. Processing is minimum-phase and zero-latency.

Dynamics tools include a Bass Compressor for low-frequency energy, a High-Frequency Compressor for harsh highs, and dynamic EQ on any band with Threshold, Ratio, Attack and Release controls. Mid/Side processing is available on every band, and sidechain control lets external signals drive individual bands. Continuous Gain Match keeps loudness constant so you can judge the processing itself.

Live Mode lets you boost or cut frequencies by playing MIDI notes. It is polyphonic, so multiple notes or chords can create several bands at once, and velocity sensitivity sets how strongly each note affects the EQ. ADSR shaping controls how the processing evolves over time, which makes the plugin usable as a performance effect.
