Although originally marketed as a “digital wave synthesizer” the ESQ-1 was actually one of the earliest Music Workstations. It’s voice generation is typically subtractive in the same fashion as most analog synthesizers that preceded it, however the ESQ-1’s oscillators are neither voltage nor “digitally controlled”, but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.\u003cbr\u003e\u003cbr\u003eThe synth also features a fully functional, 8-track MIDI sequencer that can run either its internal sounds, external MIDI equipment or both, with a capacity of 2,400 notes! It also provides quantization, step-editing, primitive forms of copy\/paste editing, and can be synchronized with external MIDI or tape-in clock.\u003cbr\u003e\u003cbr\u003eESQ-1 can store 40 rewritable sound patches internally, and features a rewritable EEPROM or fixed ROM cartridge slot for access to 80 additional patches. ESQ-M, a rackmount version of the synthesizer, was released circa 1987, with the same specifications but without the sequencer and a significantly smaller display and less user-friendly interface.\u003cbr\u003e\u003cbr\u003eNotably, the sound chip at the core of the synth, the 5503 Digital Oscillator Chip (DOC), is a brainchild of Robert Yannes, father of the popular Commodore SID chip.The chip was previously used in Ensoniq's Mirage sampler, later in ESQ-1's enhanced successor SQ-80, as well as the Apple IIGS personal computer. \u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Ensoniq","offers":[{"title":"Default Title","offer_id":46872853840115,"sku":"81ENS000","price":499.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/2433\/files\/1-Img23018.jpg?v=1746492627","url":"https:\/\/www.truetonemusic.com\/products\/vintage-1987-ensoniq-esq-1-polyphonic-synthesizer-with-gig-bag","provider":"Truetone Music","version":"1.0","type":"link"}
