Two videos on using AC Toolbox and its algorithmic functions to create a simple song. The songs are recorded in Live with Reason via rewire as the instruments. I really like using the Soul School and Polar Elements refills (see below). What I did not like was that while recording something set off Dr Rex who started playing for a few bars the whole loop. This means the Soundcloud examples are not what was constructed in the video.
DJ tech tools has a good page on the drum loop Amen break. The included video link is the uncredited work of Nate Harrison who also did the Bassline Bassline video on the 303.
