Here's some newer footage of the setup in action in 2016 (not 2018 as the upload date would suggest), in case anyone missed it!
The sequencer is Creator, which I believe is the predecessor of Notator.
Then, in a 2017 interview, the setup is still there, but isn't powered on at all despite its length (which is actually longer than that particular upload). Norman explains that the Akai disks are in the middle of being converted into modern sample files for use in Ableton on his MacBook.
