It's missing a few things... like the editor grid which has been missing since I broke it... but here's the interface after you create some channels. Certain buttons are disabled when appropriate, such as not being able to create a channel before a project.

Sweet, I'm looking forward to this as I haven't really clicked with any of the other MML editors available.

What I see as the most ambitious part yet the one I think will be the most fun is the built in "MML controller" which will basically be a way to play and record MML live on an on-screen keyboard. Essentially a virtual MIDI controller for MML! It'll be accessed with the "REC" piano button.
