Recorded this live from my 404, and stuck to the STBB and Roland rules. In keeping with the spirit of the thing I did everything on the SP. I had a blast making this, because the SP workflow is so good for just running with ideas.
Here's my 404 video submission for the Roland throwdown. This version of the song is actually somewhat different, I followed the same structure as the version above, but tried some other variations with the FX.
