Tubbutec - Wired Heart

Product information "Tubbutec - Wired Heart"
Wired Heart is a battery powered experimental sound synthesizer. It features six sensors which can detect touch and humidity. Each of the sensors controls the pitch of an oscillator: Press harder or have more sweaty hands to get a higher pitch. Touch multiple sensors at the same time to create crazy cross modulations by the current flowing through you. Each sensor serves a different function. It is best to explore the Wired Heart sound universe by trial and error.Just insert a 3V CR2032 battery and have fun!

How Does It Work?

There are two master oscillators, each controlling two slave oscillators. The slave oscillators are modulated in different ways:
The left master osc modulates the amplitude of its associated slave oscs. When the master frequency is low you can hear the two slave oscs being turned on and off alternately. Higher frequencies create weird, sometimes voice-like sounds - in stereo.
The upper right slave osc is modulated in a hardsync-like way. The osc is reset each time the master osc starts a new cycle. This creates rich sound spectra reaching from stutter to voice-like sounds to unexplainable stuff. The lower right osc is frequency modulated by the master osc. At lower master frequencies this creates tremolo effects. At higher frequencies you will hear sounds like bells or voices.
Via the stereo output jack the Wired Heart can be connected to an amplifier or headphones. The output jack additionally works as a power switch. If disconnected, Wired Heart is in standby mode and consumes very little power.


Each oscillator of Wired Heart comes with extension ports to connect additional electronics. The kit comes with 3 LEDs, 3 LDRs and a potentiometer. By using the LDRs the oscillators will react to light. This can be your hand covering an existing light source, a flashlight shining onto the heart or the light of one or more LEDs. The LEDs in turn flash with the rate of the oscillators. By simply connecting a few components you can create a never-repeating, chaotic self driven sound source.
