Generate endless, algorithmically created melodies in Random Mode, or compose your own tunes with the 16-step Manual Sequencer. Adjust tempo, synth waveform, and volume in real-time while watching the live sound on the waveform visualizer.

Fourier Series Visualization #/# Interactive wave harmonics demonstration #/# This interactive visualization demonstrates how Fourier series can approximate complex periodic functions using a sum of simple sine waves. The rotating circles represent different harmonics, and their combined motion traces the resulting waveform.
