Around 2004 I started playing with Propellerhead's Reason software and thought it'd fun to try to design a similar style of audio sequencing interface in Flash.

ActionScript 3 had just been released and I also needed a good personal project to explore the new features of AS3 particularly the audio APIs.

The eventual plan was to allow users to export their creations to an .mp3 file but other projects came up and I never got around to implementing that feature.

Still it was a fun project and provided a good opportunity to get my hands dirty with ActionScript 3.
