Harmonie Keys
A browser-based chord sequencer built for deep house producers. Four layers, original voices, and harmonic feel — no DAW required.
Browser-based · Runs anywhere · Yours forever
This isn't another chord generator built by developers who Googled "music theory."
Harmonie Keys was built by Rick Wade — a Detroit deep house producer with 30+ years on wax, 30+ labels, and a sound shaped by late-night FM radio, rare groove, and the kind of Rhodes chords that make your whole body stop and listen.
Every voice inside this tool comes from actual musical DNA — not preset libraries, not generic patches. These are the tones, the voicings, the harmonic weight that has moved dance floors from Detroit to Tokyo to Buenos Aires.
If you've ever sat down and clicked until something made you freeze — that's what this instrument is built for.
Four layers
Layer A, B, C, and a dedicated Bass lane. Stack voices, build depth, export any combination — or everything at once.
30+ original voices
Cold Keys. Night Strings. Dawn EP. Rhodes Classic. Voices designed to carry weight — not fill space.
Grimoire engine
Chord and strum samples with chromatic pitch-shifting. South Side. 73 DeVille. Lonely Strum. Textures you won't find in a preset pack.
