The keyboard Bit features 13 buttons that make up an octave of notes like a piano. This Bit can be used with an oscillator Bit to play melodies. Similar to a piano, the white keys on the keyboard are on the bottom row, and the black keys are spaced on top.The keyboard has two modes: "press", which only produces output when you press a button, and "hold", which will sustain the last note you played. You can use the"octave dial" to change the playable range. The top bitSnap is a "trigger out:", which sends an on or 5 volt signal whenever a key is pressed. Try using it with the "trigger in" of the envelope or other Bits.
