LumaKeys - Piano Visualizer
Cinematic MIDI piano videos
Only for Mac
Free
Mac
Turn any MIDI file into a cinematic piano video. 23 falling-note materials, a sampled grand piano, live key lighting, and one-click MP4 export with audio.
LumaKeys turns a MIDI file into a cinematic piano performance video, right on your Mac.
Open a MIDI file and press Play. LumaKeys draws the notes falling onto a full 88-key keyboard, plays them back through a sampled acoustic grand, and lights up each key the moment it is struck. Playback, rendering, and export all happen on your own machine.
FALLING NOTES, 23 WAYS
Choose how the notes look: clean gradients, cut gemstones, baroque filigree, veined marble, brushed gold, jagged ice shards, woven brocade, or pure light. Every material is drawn procedurally rather than tiled from an image, so notes stay sharp at any length and no two bars repeat.
COLOUR THAT IS YOURS
Pick any colour from a full colour picker, give each track its own hue, run a rainbow across the keyboard, or keep the material's own palette. The light coming off a key always matches the note that struck it.
A KEYBOARD YOU CAN DRESS
Six key textures, independent colours for white keys, black keys, and pressed keys, plus adjustable glow, hit size, hit life, and hit density. The Key Editor previews every change live against the real 88-key layout.
EXPORT A REAL VIDEO
Render your performance to MP4 with audio at your chosen resolution, frame rate, and bitrate, using hardware encoding where your Mac supports it. The exporter shows exactly which stage it is on and a live estimate of the time remaining. Finished videos are saved to your Catalog next to the MIDI files they came from.
WRITE SOMETHING SMALL
The built-in MIDI Maker gives you a piano roll for sketching a pattern, hearing it back, dropping it straight into the visualizer, or exporting it as a MIDI file you can use anywhere else.
