Sh’e in Excellent +++ Condition! I have two of the keyboard versions of this synth. I was keeping the rack around in case I moved to a smaller studio, but I think Im in my forever studio now, so here she is! I’ll include a TON of Sysex patches via email after purchase. I just noticed there’s little carpet hairs in the picture, those are not scratches :)

Ensoniq's ESQ-M is an impressive Analog/digital synthesizer rack module, released in 1986. Although the waveforms are digital in nature, the filters are all analog as on the Mirage. In fact, for a digital synth the ESQ-M has many good old analog-synth features such as a ring modulator, sequencer, and oscillator-sync. The envelopes and LFOs are can be freely routed to each DCO, VCA and or VCF.  What really sets the ESQ-1 apart from other similar synths is the voice architecture. Choose from analog, digital, or samples or any combo since there are three independent oscillators per voice! Once you start editing on the ESQ-1 you will come up with interesting and unique results. Using dynamic voice allocation it can seemlesly switch from 8-voices of analog to 8-voices of digital or sampled voices! This gives you a wide array of different sonic elements at your fingertips!Then there's its built-in sequencer. It can store up to 24,000 notes in 30 sequences and 10 songs via battery back-up. Anyone in search of a vintage synthesizer should consider the ESQ-1. More analog than a DX-7 or D-50 and also much cheaper, the ESQ-1 is a very tasty option!
