Ensoniq EPS-16 Plus

It doesn’t sample like a computer—it samples like a drummer: mono in, stereo out, no apologies.

Read the brief

The EPS-16 Plus is a purpose-built 1990 sampler that trades flexibility for immediacy. It records mono, plays back 16-bit samples at seven fixed rates, and routes everything through stereo panning and 13 effects. Its ES5505 OTIS chip gives it tight, responsive playback—but no sample rate conversion, no stereo input, and no non-destructive editing. Turbo versions added flash and SCSI, but Ensoniq replaced it with the ASR-10 in 1992. It belongs in a room where decisions are made by ear and fingers—not by menu diving.

    1990: The Year Mono Got Punchier

    It arrived in 1990 as Ensoniq’s answer to the demand for higher-resolution sampling without sacrificing playability.

    Seven Rates. No Compromise.

    Its ES5505 OTIS chip locks samples to seven rigid rates—no interpolation, no smoothing, just raw 16-bit grit.

    Turbo Wasn’t Enough

    Turbo units added flash memory and SCSI—but the ASR-10 killed the line in 1992 by going fully stereo.

The written brief2 min read

What it is and what it was built for

A 1990 sampling keyboard built for live performance and studio sketching. Designed as a direct upgrade to the EPS and Mirage, it prioritises speed, hands-on control, and sonic immediacy over flexibility or fidelity.

How it works, in terms a player would use

It records mono audio through a single input. It plays back 16-bit samples at seven fixed rates from 11.2 kHz to 44.6 kHz. Stereo output is achieved via panning and internal effects. You load samples into RAM, edit them with basic truncation and looping, then assign them across the keyboard.

What it does better than anything else

It delivers punchy, characterful 16-bit playback with zero latency from key press to sound—thanks to the ES5505 OTIS chip. Its mono input + stereo panning + 13 onboard effects creates a distinct spatial signature for drums and one-shots that cuts through dense mixes.

What it does badly

It cannot record in stereo. It has no built-in microphone. It offers no sample rate conversion on import—samples must be pre-converted. Loop editing is crude: no crossfades, no visual waveform scrubbing, no pitch-synchronous looping.

What people made with it

Producers used it for chopped breakbeats, vocal stabs, and bass hits in early 90s East Coast hip-hop and New Jack Swing. Its Turbo variants—with 2 MB flash and SCSI—enabled faster sample loading and external storage for session work.

Who should use it, and who should not

A producer who values physical knobs, instant playback, and the sonic constraints of fixed-rate 16-bit sampling. Not for anyone reliant on modern DAW workflows, multi-track recording, or sample libraries requiring high-fidelity articulation.

Is it worth your time

Yes—if you want a tactile, immediate sampler that forces decisive editing and lives in the mono-to-stereo signal path of early 90s hip-hop and R&B production. No—if you need polyphonic sampling, real-time time-stretching, or non-destructive editing.

Ensoniq ASR-10Ensoniq · 1982The Ensoniq ASR-10 is a 1992 sampling keyboard designed for live performance and self-contained music production. It integrates sampling, synthesis, sequencing, and effects in one unit. It loads samples while playing. It layers up to eight samples per instrument. It modulates them with envelopes, filters, LFOs, and real-time controls. It sequences with 16 tracks at 96 PPQN. It applies up to 62 effects — including vocoder and distortion — and resamples with them. It records to SCSI hard drives or proprietary 3.5-inch floppies. Its SCSI implementation rejects many common drives unless specially flashed. It ships in keyboard, weighted (ASR-88), and rackmount (ASR-10R) versions. It is the third-generation EPS-series sampler. It runs at 16-bit, 29.7619 kHz or 44.1 kHz. It ships with 2MB RAM, expandable to 16MB.

Ensoniq EPSEnsoniqThe Ensoniq EPS is a 13-bit sampling keyboard introduced in 1988 as the Mirage's successor. It uses dual processors and a dedicated sound engine to enable load-while-play. It reads double-density 3.5" floppies formatted to 800k. It integrates MIDI for control or computer connection. Early units suffered mechanical issues with their polypressure keyboard.

Roland MV-8800RolandThe Roland MV-8800 is a sampling sequencer. It hosts VSTs internally. It requires external video monitoring. It accepts a USB mouse. It is complex. Its hard drive is slow. Its manual is poor. One user tested it for three hours in a retail store and found it capable of handling many music production tasks.

Ensoniq MirageEnsoniqThe Ensoniq Mirage is an 8-bit sampling keyboard introduced in late 1984 as Ensoniq's first product. It offered eight-voice polyphony, analog Curtis CEM3328 filtering, and wavetable synthesis via alternative OS. It booted and stored data on a built-in 3.5-inch floppy drive — one of the first consumer uses of that format. Priced at $1695, it sold 8,000 units in its first year, undercutting the Fairlight CMI and E-MU Emulator.
