The Violet Star Key Now Exports MIDI
A Musical Key Compass by Jalen Buer
There's a moment in songwriting where the theory stops and something else takes over. You've found the key. The chords are laid out in front of you. And instead of thinking, you start hearing — a shape beneath the song, a pattern that feels less like math and more like memory.
I built the Violet Star Key because I wanted to live in that moment longer.
It started as a personal tool — something to help me see the emotional geography of a key before I started building a track. Not a chord chart. Not a circle of fifths. Something that showed me the feeling of a scale: which degrees pulled toward each other, which ones held tension, which one was the doorway out.
The result is a seven-pointed star. One point for each scale degree. The geometry isn't decorative — it maps the skip pattern of the heptagram, tracing the intervals the way a compass traces a path. Spin it to any of the 12 keys. Flip between major and minor. The star rotates. The relationships stay true.
It's free. It always will be.
What the Violet Star Key Actually Does
The tool lives at jalenrileyartistry.com/violetstarkey and runs entirely in your browser — no account, no install, no paywall.
Here's what you get when you open it:
Key + Mode selector. Choose any of the 12 keys in circle of fifths order, toggle between major and minor. The star and all its data update instantly.
Scale notes + diatonic chords. Every chord in the key, labeled by Roman numeral degree and quality. You can see at a glance what's available without reaching for a theory textbook.
Emotional tonality. Each key has a short description of its emotional character — not a rigid rule, but a starting point. C major feels different from F# minor. The tool names that difference.
Clickable star nodes. Each of the seven points on the star is interactive. Click a node and a panel opens below it showing the scale degree, interval name, chord badge, and three Tarot arcana associated with that degree. It's a system I developed to map the Major Arcana onto the scale — an extra layer of meaning for those who want it, easy to ignore for those who don't.
Elemental pattern. Fire, Water, Earth, Air — each degree carries an elemental quality that maps to the diatonic chords.
The Rose Rhythm Builder. An 8-slot chord sequencer built into the tool. Click any slot, choose a chord from the current key, and build a progression. Each completed sequence generates a short interpretive story, a reading of the emotional arc you've created.
And now: MIDI Export.
This is the update I'm most excited about. Once you've built a sequence in the Rose Rhythm Builder, hit the Export MIDI button and you'll get a .mid file — named automatically for your key and mode — that opens directly in Logic Pro X, Ableton, GarageBand, or any DAW that reads standard MIDI.
The file contains whole-note triads for each chord in your sequence, in octave 4, format 0, 480 ticks per beat. It's clean, usable, and ready to build on. The idea was always that the Violet Star Key should be a starting point — not just a reference you look at, but a thing you bring into your work. MIDI export makes that literal. You sketch a progression in the star, export it, drop it in your project, and keep moving.
No more transcribing by hand. No more losing the idea before you get to the DAW.
I named it the Violet Star Key because that's what it is — a key. Not to a door, but to a direction. A way of orienting yourself inside a key before the song knows what it wants to be.
The heptagram has seven points because scales have seven degrees. The star rotates because keys are not static — they're relationships in motion. The center is a torus void point, a place of stillness at the heart of the pattern. I call it the atrium of the song.
If you use it and something opens up — a chord you wouldn't have reached for, a progression that surprises you — I'd genuinely love to hear about it.
The Violet Star Key is free to use, free to share, and it will stay that way.
If the Violet Star Key resonates with how you think about music, there's more where it came from.
I make original music under this same philosophy — electronic, indie, cinematic. Built in Logic Pro X, colored in feeling first and theory second. You can find it on Spotify and Apple Music, and everything lives at jalenrileyartistry.com.
I also work with other creators — music production coaching, video editing and color grading, and more. If you're building something and want a collaborator who thinks this way, let's talk.
