SynthCu.be is an interactive sound toy built with CubeLab and the Web Audio API. All sounds are generated in code.

The cube surface acts as a simple sequencer. The playhead rings travel around the cube and play 6 notes, one for each color. Click a face to enable that note. Drag the cube to shuffle and mutate the song.

Change the generated sound properties with the control panel. For each of the 3 voices you can select the waveform shape and the length of the note. You can also toggle global effects and adjust the song's tempo.

Synthcu.be was built by Felix Turner with some friends at Google.
