Starlit Composer

A pure WebAudio random melody generator and step sequencer. Choose a key, style, and complexity to generate reproducible 2- or 4-bar loops from a seed; edit the melody, bass, and drums cell by cell, then mix down your work for WAV download.

Markov-style interval progression, with melodic landing notes tending toward the tonic
The pentatonic scale uses the Gong, Shang, Jue, Zhi, and Yu intervals
Kick, hi-hat, and snare are all synthesized in real time using oscillators and noise
