What Makes eSonic Fun? eSonic - Interactive Musical Toy for Children

eSonic is Fun for the Entire Family!


Lights are divided in 4 segments, each segment containing 4 stripes of 3 lights (red, green and yellow). Each segment corresponds to a music channel (e.g. drums, bass, etc.). Each stripe represents a note. As music played an appropriate stripe lights up to indicate the currently playing note.


Each of 8 buttons has a unique function:

  • Shuffle button randomly assigns new instruments to the channels;
  • Beat button toggles between waltz (3/4) and disco (4/4) beat;
  • Measure button affects the music measure length;
  • Mood button toggles mellow or happy music;
  • Mutation button affects repetition and the rate at which music changes;
  • Spread button affects max interval between subsequent tones;
  • Bridge note generates a musical bridge (e.g. drum and bass roll);
  • Density button affects the number of notes in one measure.

While the meaning of the buttons may sound obscure each button changes the character of the generated music. Also as you press a button the lights flash showing one out of eight captivating patterns. The buttons are unmarked on purpose. Just keep pushing them and discover new music and light patterns!
