EPS-16 Plus © 1990 Ensoniq
The Ensoniq EPS-16 Plus was an upgraded version of the original EPS sampler, offering improved audio fidelity, onboard digital effects, and expanded sound design capabilities. Developed by Ensoniq, it featured 16-bit linear PCM sampling, 32-voice polyphony (expanded via dynamic allocation), and a powerful effects processor integrated directly into the instrument. Designed as a true performance sampler, the EPS-16 Plus combined sampling, sequencing, and effects in a single workstation-style keyboard, making it highly attractive for studio and live use.
The EPS-16 Plus introduced built-in digital effects such as reverb, chorus, delay, and modulation, eliminating the need for external processors in many setups.
It was one of the first affordable samplers to offer high-quality integrated effects processing, a major selling point in early 1990s production environments.
The instrument supported disk-based storage via 3.5" floppy disks, allowing users to manage large sample libraries despite limited internal memory.
Its 16-bit sampling engine significantly improved audio clarity compared to the original EPS, while retaining Ensoniq’s characteristic warm sound.
The EPS-16 Plus was widely used in pop, R&B, hip-hop, and film scoring during the early 1990s.
It featured a performance-oriented design philosophy, with real-time control and expressive modulation options for live musicians.
The instrument helped solidify Ensoniq’s reputation as a leading innovator in affordable professional sampling workstations.
It is often considered a transitional device between early 1980s samplers and fully integrated 1990s workstation synths.
