Circuito Sonoro
A synth lab for curious kids
$22.99
A real modular synthesiser for children aged 7 to 10: pieces, coloured cables and an oscilloscope that shows what sound is made of. No ads, no purchases.
Find out what sound is made of — then make your own.
Circuito Sonoro is a real modular synthesiser, designed for children aged 7 to 10. Grab pieces, tie them together with coloured cables and listen to what comes out. On screen, an oscilloscope shows the wave while the Maths Magnifier turns what is happening into numbers a child can understand.
NO HIDDEN MAGIC
Every oscillator, every filter and every envelope is written number by number. What you hear is exactly the sum you see. When a child asks “but how does it do that?”, the answer is right there on the screen — and it is true.
THREE DOORS
• The Classroom: seven short lessons, each with its own gadget to play with. A speaker that shakes, a staircase of octaves, a blanket that muffles the sound.
• The Lab: eighteen pieces and free cabling. The Singer, The Blanket, The Tap, The Strike, The Robot… each with a household name and, underneath, its real name.
• The Sounds: twenty-six ready-made synths — spaceships, drums, robots, ghosts, the movie laser — to open up and take apart to see how they work.
LEARN BY PLAYING
• Ten challenges that tick themselves off as soon as you manage them.
• Slow motion: the sound goes so slowly you stop hearing it and start seeing the turns.
• Multiplying by 2 goes up an octave: the first multiplication you can hear.
• Sing into the microphone and watch your own voice become a wave.
FOR TEACHERS AND FAMILIES
The four properties of sound — pitch, loudness, duration and timbre — are four pieces you turn and hear. The website has a full manual and a classroom guide, with concepts by age and a 50-minute session plan.
IN NINE LANGUAGES
English, Spanish, Catalan, Galician, Basque, Portuguese, French, German and Japanese. The piece names are not translated: they are re-invented in each language.
REAL KEYBOARDS
Play with a finger, with the computer keyboard or with a connected MIDI keyboard. And inside GarageBand or Logic, as an Audio Unit instrument.
NO DATA, NO ADS, NO PURCHASES
No accounts, no advertising, no analytics and no in-app purchases. It works offline and nothing a child does leaves the device. The microphone is only used when switched on by hand, and nothing is recorded.
One purchase works on both iPad and Mac.
