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.
