Quantico

Quantico is an LV2 MIDI utility plugin that snaps incoming notes to the nearest pitch in a selected key and scale.

Quick Start

1. Insert Quantico on a MIDI track.
2. Choose Key (C–B) and Scale.
3. Play or route MIDI into the track.

Controls

• Key (0–11) Root note used for the scale.
• Scale (Chromatic, Major, Natural Minor, Harmonic Minor, Melodic Minor, Pentatonic Major, Pentatonic Minor, Blues, Dorian, Mixolydian) Notes are quantized to the nearest pitch in the selected scale.

Notes:

• Note On/Off events are quantized.
• Other MIDI events pass through unchanged.
