THE FIRST QUANTUM SYNTHS INSTRUMENT
MEET POLYRIFFS
Two independent sequencers. Evolving harmonic relationships. Endless rhythmic possibilities.
CONTROLLED RANDOMNESS.
UNEXPECTED MUSICAL DISCOVERIES.
Born from the rich tradition of subharmonic synthesis and polyrhythmic exploration, PolyRiffs takes those ideas into new territory.
Inspired by instruments such as the Moog Subharmonicon and Behringer Spice, PolyRiffs brings their exploratory spirit to a modern software platform—with flexible routing, deep randomization, and instantly recallable performance states.
Two independent sequencers, evolving harmonic relationships, and unconventional rhythms create a foundation for music that can be played, shaped, and transformed in real time.
Rooted in synthesis history. Built for musical exploration.

SAVE THE UNEXPECTED · PLAY THE POSSIBLE
CAPTURE YOUR DISCOVERIES.
TURN THEM INTO MUSIC.
Some of the most exciting moments in electronic music happen by accident. An unexpected rhythm. An unusual harmonic relationship. A random sequence that suddenly becomes something extraordinary.
On hands-on hardware, those discoveries can disappear as quickly as they arrive. PolyRiffs lets you capture the magic.
Save your discoveries as presets, each with 32 instantly recallable performance snapshots. Explore variations, transform sequences, and move between musical ideas live—without losing the original inspiration.
Then use Song Mode to arrange those snapshots into a song or an evolving live performance.

ABOUT QUANTUM SYNTHS
DESIGNED BY A MUSICIAN.
BUILT FOR MUSICIANS.
Quantum Synths is an independent electronic-instrument project founded by musician, composer, performer, and software developer Ned Robinson.
Drawing on decades of music-making and software development, Quantum Synths focuses on instruments that reward experimentation, spontaneity, and expressive real-time performance.
Our goal is simple: technology that keeps the music moving.
