Released in the '80s, the Ensoniq ESQ-1 was one of the primary affordably priced workstation-class keyboards on the market, combining an 8-voice, multitimbral digital/analogue cross breed synthesizer and an included 8-track sequencer. The ESQ-1's voice design permits customization of up to 3 advanced oscillators, assignable to any one of 32 waveshapes, taken after by a Curtis 4-pole 24dB/oct thunderous low-pass analogue channel and 15 routable tweak sources. The sound quality of the ESQ-1 is all-at-once advanced, warm and unmistakably '80s - a genuine pearl of the time whose sounds still ring with a brilliant profundity and character.
