FI12777.X05 200 ft 35mm There is 150 feet of tests Square wave with envelopes, attack and decay. I (Don McWilliams) have a suspicion that these are tests for the sound track of BALL BALLET aka CHALK RIVER BALLET in 1948. The film would be put to one side but reincarnated as SPHERES in 1968. Possibly, some fragments were used in PHANTASY. The final 50 feet seems to be tests with envelopes (masks).
