About the Chiptune Sequencer
This is a 16-step, 3-track sequencer using the Web Audio API. Each track uses a different oscillator waveform — square (classic NES/Game Boy), sawtooth (buzzy and bright), and triangle (soft bass tones).
Click any cell to toggle a note on or off. Each row is a musical note from C4 to C5. Adjust BPM and per-track volume with the sliders. Works best with headphones.
