E-mu Systems AUDITY Polyphonic Synthesizer System

   0 reviews  -  1014 views

    Audity was launched at 1980 AES Show but never shipped to market. The Audity was E-MU's hybrid synth dream machine. Three Z-80 CPUs drove the polyphonic keyboard, the control module and a refrigerator-sized 8-16 voice card box. The voice cards used the same SSM synthesizer chips designed by Dave Rossum for the Prophet 5, but in a much more capable configuration.

    Design Notes:

    The eventual price tag of $69,200 was too high, so it was never sold.

    Peter Baumann of Tangerine Dream did buy a batch of voice boards however, and lessons learned during development helped launch the Emulator I.

    The Audity resides at the Audities Foundation in Calgary and no longer functions.
