Tetris - Red Army (Studio Session)

’Red Army’ from Tetris (by Sphere Inc., published by AcademySoft-ELORG in 1987) running in the Player application of Studio Session Music System by Bogas Productions (1986), for 68k Compact Macs (e.g. Macintosh Plus era). Studio Session made use of the free wave form capabilities of the Sound Driver. What made it extra special was that it could play up to 6 instruments at once, beating the standard capability of the Macintosh, which could play only 4 wave forms. Perhaps the sounds were pre-mixed together in memory as they were being played back. It’s running on a mini-vMac emulator for PC in this video.
