What kidboy-firmware does
- Turn the PRESETS wheel to move between four cards: SONGS, LETTERS, NUMBERS and PIANO.
- SELECT picks one of seventeen sounds, including piano, music box, marimba, organ, flute, robot, choir, kalimba, strings and pads.
- The twelve panel buttons are drums on every card, with kick, snare, hats, clap, crash, toms, congas, claves and cowbell.
- Each card has its own kit, so the same buttons sound different on SONGS, LETTERS, NUMBERS and PIANO.
- K1 sets song speed from 50 % to 150 % and the pace of the counting dots.
- MASTER sets overall volume, covering notes, speech and drums, and OCT\u2212 or OCT+ stops everything at once.
- Kidboy saves the card, sound and speed after a short quiet spell and wakes on the saved card.
- A USB computer sees KIDBOY FM-1, sends notes that play the current sound, and receives the notes you play.
Its modes
- SONGS
- Each of the 27 keys plays a nursery song, with the title on screen and Todo Boy bobbing along.
- LETTERS
- Keys show a giant letter A to Z, say its name and play a note, with the ABC song on the rightmost key.
- NUMBERS
- A key says its number and lights that many dots one by one, each dot with a note.
- PIANO
- Every key plays its real pitch across two octaves and shows the note name.
