Starion, Fantasia had it more than 65 years ago
CINERAMA (1952) movies had 7 channels
CinemaScope (1953) (and later even some Standard Widescreen prints) had 4
70mm (1955) had 6
Ben Hur in UltraPanavision/MGMCamera65 (1959), using Perspectra coding to move the surround channel arround brought up the number of channels to 8
of course, Fantasia actualy seems to've used a kind of "human" manned Perspectra "code" (probably a paper with instructions

) so in that sense on theaters equiped with the full 90 Fantasound speakers and a skilled Fanta "dude", it woulda been truly a most multichannely esperience, if not
the most
