Overview

Blue Melody listens to your track and reads the key, the chord, and the notes that clash — live, as you play. It guides your melody and harmony without ever getting in the way, right inside FL Studio and any VST3 host.

What it does

Live key & chord detection

Blue Melody reads the key and the chord under your cursor in real time, so you always know what you’re writing over — no guesswork, no theory degree required.

Frequently asked questions

What is Blue Melody?
