EVERY SESSION STARTS HEREBefore the music there is setup. Sounds to find. Plugin chains to wire. Chords to build.MONOCHORD is for producers who don’t need help knowing what sounds good. They need a faster way to get there. One key plays a full chord of up to complex nine notes with sound and effects already in place. Everything goes to the DAW as MIDI or audio.

MONOCHORD

WHAT IS MONOCHORD?

An instrument for musical ideas, not a chord generator. Made for the start of a track and for the moment it stalls.

FACTORY

FACTORY builds a complete sound in one click and reshapes all 15 effects. The same preset, a new character and starting point each time.

CHORDS, VOICED BY HAND

600 chords in 70 tonal sets, placed the way a pianist would play them and not calculated by rule. Each one can be adjusted or trimmed.

THE PROCESS

MONOCHORD makes no choices for you and holds no generative AI. Taste is not automated. It removes the effort, not your intention.
WHY MONOCHORD?
“Every session used to start with stolen time: chains to wire, presets to scroll, theory I never learned. I come from sampling, where chords were found on records rather than played. MONOCHORD gets me to an idea before the setup used to be done, often to one I would not have played by hand. It works anywhere, in the studio or far from it. It is an assistant without AI; the choices stay mine. I am the artist, not the computer.”
Damiano von Erckert (DJ, Producer)

THE SOUND

Rooted in 1980s to 2000s analog and digital hardware, decades of studio sound in one instrument.The warmth of vintage machines in a library built for chords. Every sound was shaped to be played as a voicing and not only as a single note.

MIDI ROUTING TO HARDWARE AND DAWS
Everything MONOCHORD plays is sent as MIDI, not the chords alone but the full performance: the arpeggios, the strum, the humanisation, the timing. It routes to external hardware or to any instrument in the session, so other synths and plugins receive the complete part and play it note for note.
MULTISAMPLE - USER SOUNDS
The library is left open, so your own recordings can be placed into the sample zones and saved beside the original sounds. The instrument then voices your material as it voices its own, sounding your samples as a full chord.

MONOCHORD by the pool

Watch an uninterrupted improvisation, performed entirely by mouse. The audio is an iPhone field recording. No further signal or plugin was added.

“Every session begins with stolen time: plugin chains to wire, music theory to learn, static sound presets scrolled in search of a certain character. I never trained as a pianist, and the chord voicings of my favorite film scores, club records, ambient and jazz albums often stayed out of reach. MONOCHORD ends that argument. The final design is a chord instrument, with an on-screen keyboard drawn large enough to play by mouse or a single key press. The effort falls away, leaving the sound and feel of vintage studio hardware and sampling culture. It is here to assist, never to replace creative intention and choice.”
