The Emulator had a very basic 8-bit sampler; it only had a simple filter, and only allowed for a single loop. The initial model did not even include a VCA envelope generator. It came in three forms: A two-voice model (only one of these was ever sold), a four-voice model, and an eight-voice model. When the original Emulator was turned on the keyboard was split. It was designed to be played in split mode, so playing the same sound on the full keyboard required loading up the same sound floppy disk in each drive.
