Standalone Harmony Instrument – Circle of Fifths Interface with 7-Partial Synthesis & Arpeggiator
Product Details
Discover a new way to shape rich, complex harmonies. This standalone instrument maps the Circle of Fifths directly to a physical interface, making beautiful chord progressions intuitive and expressive. Featuring three synthesis models (additive FM, subtractive, granular), seven individual partial controls, a manual arpeggiator, and a handcrafted solid walnut enclosure, it’s designed for musicians who want deeper harmonic exploration. Powered by USB-C or rechargeable AA batteries, it’s ready for studio, stage, or anywhere inspiration strikes.
Product Features
🎵 Circle of Fifths Interface – The only instrument that maps harmonic theory directly to keys, making complex chord progressions easy to discover and play.
🎛️ Three Synthesis Models – Choose from additive FM (7 partials), classic subtractive (PWM, saw, triangle), or granular synthesis for versatile sound design.
✋ Manual Arpeggiator Fader – Strum chords like a guitar or harp; the arpeggiator intelligently skips notes when moving quickly, giving you fluid, expressive control.
🧱 Handcrafted Walnut Enclosure – Solid walnut housing with Cherry MX Silent Red keyswitches for a premium tactile feel and natural acoustic resonance.
🔊 Built-In Surface Transducers – Turns the walnut body into its own speaker, letting you hear the warm sonic engine through the instrument itself.
🔌 Studio & Portable Ready – USB-C powered (4-17V) or runs on 4 rechargeable AA batteries. Features USB MIDI out and stereo 1/4” audio output.
🎚️ 7 Faders for Harmonic Partials – Control the first seven overtones independently for deep timbral shaping.
🎛️ Detuning & FM Per Partial – Detune individual oscillators or apply curated FM ratios to create bell-like and inharmonic textures.
🎚️ Two-Stage Filter Envelope – Control attack length, cutoff frequency, decay length, and decay slope for dynamic shaping.
✨ Built-In Reverb – Simple decay and dry/wet controls add space and depth to your sound.
🔘 Shift Button for Note-by-Note Building – Temporarily plays only root notes, letting you construct complex chords note by note.
🔄 Multiple Play Modes – Immediate Trigger, Bass Line, and Arpeggiator-Only modes for varied performance styles.
🎛️ Alternative Synthesis Models – Switch to Subtractive (Triangle, PWM, Saw, Sine/FM) or Granular models for expanded sonic possibilities.
