This may have already been answered but...

They created taped tracks of real vocals, one for each note they
planned to use. So they had a track of E, A, F#, etc. and assigned
each one to its own channel of the mixing board. The vocal note was
continuous for the length of the song (tape looped). They
then "played" the notes by moving the sliders on the mixing board up
or down. That's why it has such an interesting attack to the notes.
Bring up three sliders get a chord. Bring up all of them for an
interesting cluster like at the end of the song.
This song still sounds great today.
