Check out Peter Grenader's write-up of Subotnick's control tracks:
         http://www.buzzclick-music.com/mort_lore.html

Subotnick used sine waves because he could multiplex multiple signals 
onto each tape track, using a "comb filter" (a filter bank with a 
separate output for each band) as a demux. Clever.
