Tools forged from the deep history of rhythm and voice, built for producers who want their music to feel alive.

Make any groove feel better.
The Rhythm Gooderizer turns stiff, lifeless patterns into grooves with real pulse. It is built on the research of three masters of rhythm: Godfried Toussaint's mathematics of what makes a rhythm "good," David Peñalosa's study of clave as the hidden key behind African and Afro-Cuban music, and Adam Rudolph's approach to cycles and rhythmic language. Hundreds of years of rhythmic wisdom, in one tool.
A vocal synth of the four temperaments.
In the ancient world, eucrasia meant the perfect balance of the four humours, the harmony of body and spirit. Eucrasia is a vocal synthesizer with four distinct singing voices: Soprano, Alto, Tenor, and Bass. Each voice is a character with its own personality, drawn from one of the four elements and the four temperaments of antiquity: Sanguine, Choleric, Melancholic, and Phlegmatic. Play them alone, or bring all four into balance as a full choir.

Soprano
Fire · Choleric
The bright lead, sharp and pressing, that cuts through the choir.
Alto
Air · Sanguine
The warm middle, open and breathy, that carries the harmony.
Tenor
Water · Phlegmatic
The calm current, steady and cool, that holds the line together.
Bass
Earth · Melancholic
The deep root, grave and grounded, that the rest of the choir stands on.

One melody, two singers.
A hocket splits one melody between two voices, each singer filling the other's gaps. A bluebird and a robin trade every note. Load your own MIDI file, loosen the hocket with a Bernoulli gate, give each bird its own sound, and sync it all to your gear.

A daily rhythm koan.
Each day, Clave Koan plays one of the world's great rhythm timelines. Place its strikes on a circle of pulses and find it in six tries. A few minutes a day trains your ear on the patterns under salsa, Afro house, reggaeton, samba and techno. Solve it and the koan opens: the rhythm's name, where it comes from, its interval pattern, and how producers use it in the studio.
Name any chord, from any direction.
Chord Lens is a reverse chord finder. Play notes on a piano keyboard or a guitar fretboard, or send them straight in over MIDI, and it tells you the chord: root, quality, and every other name those same notes can wear. Triads, sevenths, sixths, sus chords, and ninths, with slash-chord readings for inversions.

A chord for every step of the scale.
Harmonize any scale, up and down, in all 24 keys, on keyboard and guitar. Four centuries of answers to one question, from the Baroque Rule of the Octave to Barry Harris and gospel. Thirteen ways to harmonize the same scale, side by side, with MIDI export for any line, key or the whole collection.
Play one note. Hear four centuries answer.
Chorale Generator puts the harmony of Bach, the hymnal and the Renaissance under your melody, one note at a time. It shows you the chord the masters reached for, where they went next, and writes it out in four parts. Compose a melody, import MIDI, or play it live, then export all four voices to your DAW.

Score any scene the way the silent-film pianists did.
Photoplayer turns the mood books of the 1910s and ’20s into a cue generator. Pick a mood or describe your scene, hear an orchestrated mock-up, and take MIDI into your DAW.
