Workflow Preview

From mode selection to editable MIDI in under a minute.

Start in Crucible to define the harmonic field, move into Procession to arrange it, use Transmutation when the section needs a new center, use Cipher to map your ideas to an instrument, and preview the result through Aether.

Harmonic Field

Crucible

Build the harmonic field before it becomes a progression.

Crucible keeps the writing grounded in harmonic structure instead of random chord browsing.

Seven diatonic stations for the active key and mode

Chord shape, voicing, inversion, top-line, and voiced-tone control

Phrase-role aware chord identities and transition hints

Who It Is For

Built for musicians who want harmonic control.

Producers stuck in four-chord loops

Move beyond familiar progressions by building from modal structure instead of guessing.

Guitarists and keyboardists writing in a DAW

Check how harmonic ideas map onto real instruments before exporting MIDI.

Composers learning harmony by doing

Explore modes, degrees, inversions, extensions, and key movement through a hands-on writing surface.

Musicians who want control, not random generation

Use guided harmonic tools without giving up authorship of the final progression.
