What is Online Sequencer?
Online Sequencer is a free music sequencer that runs in your browser. You click notes onto a piano roll grid, choose an instrument for each part, and press play to hear your tune. You can start making music straight away without logging in.
Each instrument has its own volume, delay, panning, detune, reverb, distortion, equalizer and envelope controls, and there is a built-in synthesizer with basic waveforms, filters and an LFO. Songs can be shared with a link, saved offline, exported as MP3, WAV or MIDI, and you can import MIDI files. The site also has a large library of songs made by other users, plus a forum, a chat and a wiki.
