Ear Modular Solar Sound Card - Listen With Your Eyes

There's something wonderfully liberating about instruments that break free from traditional control paradigms. Knobs and keys are fantastic, but what about the light filtering through your window, the shadow of a passing cloud, or the flickering of a candle? The Solar Sound Card from Chinese experimental studio Ear Modular invites you to explore exactly this - a pocket-sized instrument where light becomes your interface and the environment becomes your collaborator.

Light as Music

The Solar Sound Card is a light-sensitive portable sound generator that extends the Ear Modular philosophy beyond the Eurorack format. Its circuitry responds to ambient light, transforming sunlight, shadows, and small light sources into dynamic sonic textures. Wave your hand over it and the sound shifts. Walk outside with it and the sun becomes your modulation source. Cover it partially with your fingers and sculpt the tones in real time.

The instrument encourages what Ear Modular describes as a synaesthetic approach - "listen with your eyes and see with your ears". Rather than presenting a grid of buttons or a row of faders, the Solar Sound Card asks you to pay attention to something we usually take for granted: the quality and movement of light around us.

Self-Contained Simplicity

What makes the Solar Sound Card particularly appealing is its complete self-sufficiency. Each card contains an integrated speaker and runs on a coin-cell battery, making it a truly portable instrument. No cables, no power supplies, no setup - just pull it from your pocket and start playing with light.

For those who want to incorporate the sounds into a larger setup, an audio output jack provides connectivity. The output offers SP+ on the tip and SP- on the ring, allowing connection to external speakers, amplifiers, or recording equipment.

Seven Voices

Currently, seven different types of Solar Sound Cards are available, numbered Type I through Type VII. Each variant features its own unique circuitry and character, producing distinct sonic results from the same light input. Some might produce harsh digital textures, others warmer oscillations - the diversity means you can find a voice that suits your aesthetic or collect several for a variety of tonal options.

This approach of creating variations on a theme is characteristic of Ear Modular's experimental ethos. Rather than trying to build one "perfect" instrument, they embrace the differences between circuits and present each variation as its own valid voice.

About Ear Modular

Ear Modular is a synthesizer module development studio based in China, founded by enthusiasts deeply immersed in the world of modular synthesis. Their philosophy centres on experimentation - creating distinctive instruments that challenge conventional approaches to sound generation and control.

Beyond the Solar Sound Card, Ear Modular produces a range of Eurorack modules and controllers with names like Windstring, Paperbird, and Night Rain. The poetic naming reflects their artistic approach to instrument design, treating each creation as something more than just a piece of gear.

Who Should Consider It

The Solar Sound Card suits anyone curious about alternative approaches to electronic music making. If you're drawn to the idea of environmental interaction, generative textures, or simply want a tiny noise-maker to carry around and play with during quiet moments, this delivers something genuinely different.

It also makes an interesting addition to field recording sessions or sound walks. Instead of just capturing the world through a microphone, you can let the world's light play an instrument while you move through it.

The Solar Sound Cards are available through Sonic Seed, with prices starting around £20-25 depending on the type.
