Scaler EQ Pro

Scaler EQ Pro is a note-aware equalizer that shapes frequencies in relation to your key, scale, and harmony. Built on patented musical EQ technology, it boosts in-key frequencies and reduces out-of-key content, with automatic key detection and three scale slots for moving between tonalities. The redesigned filter engine offers smoother Harmonic Peak filtering, continuously variable slopes, and a full toolkit of traditional bands including tilt, notch, shelf, and cut filters. Dedicated bass and high-frequency compression, continuous gain match, and a MIDI-controlled Live Mode let you play the EQ from your keyboard. Use it to keep instruments harmonically coherent, clean up audio, transform textures into playable pads, or add width and focus on the master bus. It suits hobby producers and musicians working in FL Studio, Ableton, or Logic who want musical intelligence at every stage of mixing, mastering, and sound design.
