Keys and octaves

PocketTone is monophonic, like the pocket synths it comes from. Hold one key and press another, and the new one sounds; let it go and the first one comes back. Slide a finger along the keys and each note hands over to the next without a gap, so a glissando stays smooth. Several fingers are tracked at once.

The keyboard is three octaves of white keys, C to B, but seventeen white keys fit on screen. Drag the thin slider under the keys to move the window, or tap the ◀ ▶ at its ends to step one key at a time. iPhone and iPad show the same seventeen.

OCTAVE shifts the whole keyboard down or up an octave. On MID the leftmost C is middle C.

The first eleven white keys carry printed legends:

• A digit, 0 to 9 and then 0 again. In calculator mode these keys are the keypad. See The calculator.
• A rhythm name on the ten keys after the first, from MARCH to BEGUINE, in the order the LCD's ◀ ▶ steps through them. They are labels only: you pick a rhythm on the LCD, and the keys always play notes.
