Welcome to the Online Sequencer Wiki, a wiki for using and navigating Online Sequencer. Online Sequencer is a web-based music sequencer that allows users to create music saved online or on their computer and share it with other users.

About Online Sequencer Online Sequencer was created by Jacob Morgan and George Burdell in 2013. Users can create a sequence by placing notes in a piano roll-style interface. Over time, various features were added, such as new instruments, effects, and control options for sequences. The community around the site also expanded, adding a forum, chat, and this wiki. All dates on this wiki are stored in the MM/DD/YYYY or MM/DD/YY; please do not alter this.
