User Manual
The micro sequencer sends out voltages based on the position of
each of the four “step” knobs. Connect it to an oscillator and it will
step through the “sequence” consecutively to make a melody (The
LEDs tell you which step is active). Turn a knob fully counterclock-
wise to make the step silent. Use the module in “speed” mode to set
the speed using the dial, or flip the switch to “step” mode to use an
input module like a pulse or button for control. It also has a trigger
output, which you can send to any of your other modules.
The keyboard lets you play melodies – it features 13 switches
that make up an octave of notes. It has two modes: “press”
(which only produces output when you press a switch) and
“hold” (which will sustain the last note you played). It also
features an octave control which changes the playable range.
In addition to its main output, which is great for controlling our
oscillators, it also has a “trigger out”, which you can send to
the “trigger in” of the envelope or other littleBits modules.
ELEMENTS OF A SYNTH
CONTROLLERS
Controllers do exactly what it sounds like they
do; they control elements of a synthesizer.
Sometimes controllers are familiar like a
keyboard and some are lesser known like a
sequencer. The Synth Kit has both!
The control can come in the form of control
voltages or triggers. A control voltage is
usually a changing signal that is often used to
control the pitch of an oscillator. A trigger
is a short voltage pulse that is commonly used
to trigger or “turn on” other parts of circuits.
Triggers are also good at generating rhythmic
patterns.
To see how triggers are used, go to page 24
for the Percussion Party project.
