The Synth Kit gives you the power to design and build unique and reconfigurable sound machines to your heart’s content. Take a look at what you can make with the 12 Bits™ Modules included in the kit. Let the music begin!
This electronic instrument uses a winning combination of Synth Bits™ Modules starting with a keyboard, moving through two oscillators, the envelope, the filter, the delay, and ending up with the synth speaker! Plug in to exterior speakers to rock out super loud!
In this circuit, the keyboard is a controller that let’s you play up to 4 octaves of notes to make melodies. The melody is split and passed through two oscillators, the main sound generators, and the envelope before making its way through the filter. The envelope is a modulator that alters the audio signal in addition to the oscillator. You can adjust the “attack”, which is how long it takes to ramp up to maximum volume, and the “decay”, which is how long it takes to go down to silence again. The filter has the biggest effect on the sound’s character or “timbre”. It effects the timbre by changing the relative volume of certain frequencies in the sound. Last in line before the speaker is the delay module, which takes incoming audio and repeats it, like an echo. It has two knobs: “time”, which sets the delay length between a sound and its repetition, and “feedback”, which controls how many times the sound repeats.
Play your Synth Kit like a D.J.! With two turntables attached to the two oscillators, you can make a variety of sounds with the spin of a disk. This sound circuit was designed to mimic the sounds a DJ might make when scratching the turntables.
In this circuit, the micro sequencer is a controller that triggers a four step sequence, sending out stepped voltages to make melodies or rhythmic patterns. This pattern is then split and passed through two oscillators. The oscillators, which produce the sound from the patterns coming out of the micro sequencer, adjust the output tone when the pitch knobs are turned. The spin disks fit snugly on the oscillator knobs, thus adjusting the output tone of the sound when you spin them. The mix module is a modifier that takes the signal from the two oscillators and sends them to a single output. The envelope is a modulator that then alters the audio signal in addition to the oscillator. You can adjust the “attack”, which is how long it takes to ramp up to maximum volume, and the “decay”, which is how long it takes to go down to silence again. The synth speaker at the end of the circuit outputs the sounds you make. We added some wires and bright leds at the end of our circuit, which pulse depending how the sound is modified.
LIGHT SENSITIVE SOUND
The Synth Kit in combination with other littleBits modules can be magical. You can create visual, light, and mechanic interfaces galore. Let the fun begin with this light sensitive sound circuit. This basic circuit allows you to alter the pitch of the oscillator by changing the amount of light around the light sensor. The simplest circuit you can make with the Synth Kit is power + oscillator + synth speaker. By adding the light sensor, you add a whole new interactive dimension to your sound circuit.
