Vintage 1987 Ensoniq ESQ-1 Polyphonic Synthesizer With Gig Bag
=
To keep it simple, here's the main point: this true 80’s classic is ready and waiting for you to get your Depeche Mode on!
We just took this synth in, and it's available on a great deal. It's in good condition. Now, for those to like to read more, read on!
The ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer and originally released in 1985. 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.
The 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.
ESQ-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.
Notably, 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.
