Ensoniq EPS (1988–1991)

Name: Ensoniq EPS
Brand: Ensoniq

A 13-bit sampling keyboard that succeeded the Mirage, with full MIDI implementation.

Overview

The Ensoniq EPS is a digital sampling synthesizer released in 1988. It was built as a performance-oriented sampler and replaced the Ensoniq Mirage. Internal processing runs at 24-bit resolution, even though the samples themselves are 13-bit. On startup the display reads "ENS ONIQ EPS-16 PLUS" and then "PLEASE INSERT DISK", because samples load from floppy disk. MIDI In, Out and Through ports are on the back for studio setups.

Design

The EPS is a 13-bit digital sampling synthesizer, and all of its internal processing is 24-bit. The startup screen shows "ENS ONIQ EPS-16 PLUS" and "PLEASE INSERT DISK". That is the boot sequence, and it depends on external floppy disk storage. The unit supports polyphonic aftertouch. It was engineered to offer better sampling than its predecessor, the Mirage.

Context

The EPS replaced the Ensoniq Mirage, widely regarded as the first affordable sampling keyboard. It was positioned as a more advanced performance sampler. It was part of Ensoniq's push into professional sampling instruments before the 16-bit EPS-16 Plus came out.
