In my head, a DAW is exactly what it says. A workstation for digital audio. That said, this has the potential to evolve to something more similar to existing professional DAWs and maybe even surpass them.

I'm glad you like it. The sound is generated purely by a JavaScript function returning sample values that are then handled by the Web Audio API and buffered. That's how you hear sound.

On edit: It's really easy to remix tracks that way, even small changes to values yield quite different results. It's fun!
