Synths ⇝ Ensoniq ⇝ Ensoniq SQ-80

The Ensoniq SQ-80 is the successor to the Ensoniq ESQ-1 and has a few upgrades, including a larger selection of waveforms (plus all of the ESQ-1's original waves), a keyboard with polyphonic aftertouch, a floppy drive, and expanded sequencer memory.

The expanded waveforms include a selection of waveforms meant to aid in the simulation of acoustic instruments. They include inharmonic loops (5), transient attacks (11), sustain loops (17), drum sets (5), and drum sounds (5).

An optional memory cartridge adds 80 more user-programmable patch memories. Patches can also be saved to floppy disk.

The SQ-80 uses CEM3379 analog filter chips.

It was followed a year later by the Ensoniq VFX.
