Ensoniq SQ-80

Released in 1987

The Ensoniq SQ-80 is an eight-voice, polyphonic, poly-timbral synthesizer, capable of playing eight different sounds at once, with dynamic stereo panning for each voice. It's a wavetable synth with 75 waveforms, analog filter and VCAs, a 61-note keyboard with velocity and aftertouch, and a floppy disk drive for storing patches and sequences.
