Dungeon Machines: Legend Of Grimrock Editor

I've only just found time to start playing Legend of Grimrock, despite awaiting it eagerly for months. Maybe I'll manage to finish it before the release of the dungeon editor, although the latest post from Almost Human suggests not.

...we’ve reached internal beta! All the features and functionality is done, now all it needs is just a little bit of polishing and bug fixing and then we can unleash it into the wild. We’re getting close to the finish line, folks!

But will it be possible to create a step sequencer using the editor, turning dungeons into giant drum machines? If only a video could answer that question. If only that video was just below these words.

It's a 'yes' then.
