Like other NIN releases, some songs never made it to the final album. In this case, some songs were "[[The Beauty Of The Drug]]", which was a general out take, and "[[Just Do It]]", which was a track prompting the album's protagonist to kill himself. The latter was axed at the request of [[Flood]], who refused to have anything to do with it.
An article from Sound On Sound contains a list of some of the equipment used on the album:
<blockquote>"The studio was equipped with a 56-input Amek Mozart console with Rupert Neve modules, two Studer A800 Mk3 multitrack machines, Mac-based Pro Tools and a host of outboard gear, in addition to Akai S1100 and Kurzweil K2000 samplers; Prophet VS, Digidesign Turbosynth, ARP Odyssey, Oberheim Expander, Oberheim OBMx, Roland MKS80 and Minimoog synthesizers; Doepfer and Oberheim sequencers; a Mellotron MKIV polyphonic tape replay keyboard; a Roland R70 drum machine; and assorted Jackson and Gibson guitars."[http://www.soundonsound.com/sos/sep12/articles/classic-tracks-0912.htm]</blockquote>
