01 / Concept

A synthesizer you can take apart.

Molecule Synth breaks a traditional synthesizer into physical building blocks: sound, control, modulation, and output.

Each circuit lives inside a color-coded hexagon. Connect the modules, change their order, turn a knob, cover a light sensor, press, flex, listen—then pull the whole instrument apart and build another one.

“An open-ended, hardware-based instrument that is DIY to the core.”

The Molecule idea
  1. 01

    Connect

    Snap independent hexagonal circuits into a signal path.

  2. 02

    Control

    Use knobs, light, pressure, flex, joysticks, or MIDI.

  3. 03

    Transform

    Reorder the elements and discover a different instrument.

02 / Elements

Nine modules.
Countless routes.

The original available elements span audio, sound generation, elemental modulation, tactile control, and computer control. Every module is a visible part of the circuit—and an invitation to experiment.

Lfo, by design. Its range runs from pulses taking more than a minute to complete all the way into audible frequencies, allowing the same hex to work as a very slow modulator or a sound-generating oscillator. That wide range follows a tradition established by early modular-synth pioneers—and gives the player maximum flexibility.

03 / See + hear

Not a black box.

Molecule Synth makes the path from gesture to electricity to sound visible. The result can be melodic, noisy, unpredictable, or all three at once.

05 / Origin story

From circuit-bent toys to a new kind of instrument.

Travis Feldman created Molecule Synth to make electronic sound wilder, more physical, and less predictable than a traditional keyboard.

The idea grew from circuit bending and hand-built instruments—and from a desire to move beyond sealed “black box” technology. Instead of asking musicians to consume somebody else’s system, Molecule exposes the system and invites them to rebuild it.

The project launched from Portland in 2012. During early demonstrations, people from age 6 to 86 picked it up and began experimenting without needing technical knowledge.
