The plugin

A VST3 and Audio Unit plugin, in every license.

Included with every license. Nothing extra to buy or activate.

Same engine, same panel, on a track in your session. Capture a melody from your song, generate the parts, and hear them play back in place.

01 / In the session

What it does for you.

Start from your song.

Press Arm, play the take or run the clip, and the melody lands in HarmonyKeen at your tempo, on the bar you played it.
Hear it in the mix.

The harmony plays through the instrument on the track and follows your transport. Regenerate, mute, solo, all while the song runs.
Each voice on its own track.

Drag the harmony onto your session and every part arrives on its own named track. Or export MIDI, with or without the melody.
Saved with the project.

No files to manage. Melody, harmony, preset and settings travel inside your DAW's project, per track.
