VERT turns researched harmonic language into progressions you can shape, hear, edit, and hand to a DAW. Choose one of 56 focused genre profiles, decide how closely to preserve its evidence, then control key, mode, length, surprise, complexity, voicing, rhythm, and every chord in the result.
Artwork placeholders for genre profiles, build modes, harmonic controls, chord editing, audition, and MIDI handoff
The catalogue reaches from City Pop, Neo-Soul, Shoegaze, UK Garage, and Amapiano to MPB, Modern Country, Metalcore, Doo-Wop, Bluegrass, and 1970s Funk. Each focused profile has its own harmonic vocabulary, cadence rules, density, voicing, and playback defaults
The runtime table compiles 1,539 weighted ledger rows, 1,426 genre-scoped structural cycles, and 639 sources spanning 360 named works. Multiple sections from one work are normalized before selection so documentation volume does not become extra lottery weight
Adapt reshapes one selected archetype onto a regular grid. Preserve keeps one complete weighted evidence progression. Combine joins typed two-to-four-chord motifs while requiring every engine-made connection to pass the genre transition grammar
Choose tonic, automatic or explicit mode, automatic or 20–400 BPM tempo, and 1, 2, 4, 8, or 16 bars. Surprise changes evidence reach, Complexity changes harmonic detail, and Voicing moves from close to open spacing
Lock or reroll individual chords, drag cards into a new order, edit roots and qualities, reshape whole-beat harmonic rhythm, and move MIDI notes in the expandable voicing editor without giving up deterministic recall
Preview through eleven internal instruments and seven rhythms, follow host transport, or send live MIDI. Drag, copy, or save a MIDI file carrying tempo, meter, modal key metadata, chord markers, channel-one voicings, and a channel-two bass line
VERT does not begin by pooling every chord it knows. It selects or constructs a genre-valid lineage, resolves a key and mode, realizes legal transitions and cadence behavior, then voices, rhythms, auditions, and exports the finished cycle.
The first progression is a proposal, not a locked answer. VERT keeps the musical evidence visible enough to guide the next decision while giving every chord, duration, voicing, and handoff an editable surface.
Start from one of 24 factory entries—or address any of the 56 profiles through the automatable Genre parameter—then set the tonic and keep the evidence-selected mode and tempo or override either explicitly
Use Adapt for a regular production grid, Preserve for a complete evidence cycle, or Combine to compose a new phrase from typed motifs inside one genre
Lock strong chords, reroll weak ones in context, reorder or edit cards, then tune harmonic rhythm, individual MIDI notes, Surprise, Complexity, Voicing, and playback pattern
Audition internally, follow host transport, enable live VST3 MIDI where supported, or drag, copy, and save a Standard MIDI File for arrangement and sound design in the DAW
24Factory genre starts
The factory Genre Library covers 24 representative starting points across Organic, Groove, and Electronic families. Each entry selects a profile and applies its authored complexity, voicing, rhythm, and four-bar working setup.
Search and category filters keep the factory-only library focused; all 56 profiles remain addressable through the automatable Genre parameter, with no user-preset or favorite layer
