The Ensoniq Performance Sampler (EPS) was one of the first few affordable samplers on the market. It was manufactured from 1988 to 1991 by Ensoniq in Malvern, Pennsylvania, US. The EPS is a 13-bit sampler and replaced the Mirage - widely regarded as the first truly affordable sampling keyboard.
The EPS has a straightforward interface that is easy to use, with configurable controls geared for live performance. Because it has two processors, it can load and play up to eight instruments simultaneously (with another eight on reserve). The display is a 22-character, single-line vacuum fluorescent display. It boots from an integrated floppy disk drive (sourced from Sony or Matsushita), or from a SCSI drive connected to the expansion bay. The EPS has 256 Kwords of RAM on board. Ensoniq offered both a 2x (512 Kword) Memory Expander and a 4x (1 Mword) Memory Expander with SCSI interface. A company called Maartists offered both 4x and 8x memory expanders, allowing a total of 2 Mwords RAM. Extra RAM allows for longer and higher quality samples. The "2x" expander contains one 1x256Kbit and three 4x256Kbit chips, for a total of 13x256Kbits in addition to the onboard memory. The EPS is unusual in having a 13-bit sample memory word length, left-justified into the most significant bits of a 16-bit word.
The EPS uses double-sided, double-density 3.5" disks, formatted to 800k with ten 512-byte sectors per track. It can also read (but not write) Ensoniq Mirage sample disks.
The EPS uses MIDI and can be used as a controller of other instruments or connected to a computer.
The EPS was superseded by the EPS-16 Plus which upgraded the sample size to 16 bits and added a 24-bit effects system. Other improvements include CD-ROM support in the optional SCSI interface and FlashBank storage for the OS and favorite sounds.
The keyboard is of thick plastic construction of a dark gray color with 61 weighted keys. There are assignable pitch, modulation wheels, and two patch select buttons. The interior of the unit is accessed by removing four hex screws under the front of the keyboard and swinging open the rear-hinged control panel.
The whole unit is configurable through a custom operating system (latest version was 2.49 for the EPS and 1.30 for the EPS-16 Plus). After the system boots from the floppy drive, it flashes a "Tuning Keyboard - Hands Off" message while it calibrates its polyphonic after-touch keyboard. The EPS-16 Plus is capable of storing the OS in the optional FlashBank, which removes the need for a boot disk.
An optional Output Expander module allows access to eight discrete mono outputs on the machine, allowing to separately mix levels and effects for each loaded sample.
The key limitations of the EPS were its proprietary disk format, and later a lack of support from Creative Technology, the current owner of Ensoniq. A 19" rack-mount version of both machines were also available in limited numbers.
This model was superseded by the EPS-16 Plus, released in 1991. The EPS-16 Plus is very similar to the EPS. Its main addition is integrated DSP effects and stereo audio routing. Due to the upgrade to 16-bit audio, the Output Expander on the EPS-16 Plus is different, instead providing three pairs of stereo outputs, two from before the new effects chip.
The EPS is a performance sampler. Besides the main processor it contains a dedicated sound engine so that playing can be done whilst loading another sample. The main processor handles the I/O while the sound engine is responsible for keeping the audio running without interruption — this made the EPS especially useful for live performance situations.
The interface, although operating through a single-line fluorescent display, offers rapid access to all functions by the intelligent way that functionality is broken into Modes and Pages.
Modes are: Load, Command, and Edit.
Pages are: Instrument, Sequence, MIDI, and System.
In addition to eight soft instrument buttons, it has a number pad (0-9), four cursor buttons, a value slider, and 'Yes' - 'No' buttons.
The vast majority of functionality can be accessed with less than three clicks: Mode - Page - Number Pad.
There is also a dedicated button for Sampling, and three for the built-in sequencer. The EPS-16 Plus also has a dedicated button for configuring the effects DSP.
Easter Egg: There is a hidden menu in the Command-ENV1 page which contains Software Information, the names of the designers, a DC Offset Adjustment, and a keyboard calibration command.
Instrument pages are prefixed by clicking a Mode (Load, Command, or Edit) -- yielding functions relating to loading, editing, and tweaking EPS sampled instruments. Instruments can contain a number of discrete samples which are patched into Layers - each with their own ADSR-like envelopes and keyboard ranges. A loop editor allows you to define envelopes, cross-fades, and sample start-end, and loop points in real-time. It is possible to modulate the loop start with any source to give complex evolving sounds. On the EPS-16 Plus, the Transwave loop mode allows the start point to be modulated in exact "single-cycle" steps, giving effects similar to the PPG Wave. The Ensoniq manuals were famous for including quality tutorials for sampling and editing new sounds.
The Sequence pages allow you to define sequences and songs. Simple quantization is available, along with a crude, but effective, step-editor to tweak individual sequence elements. Sequences (with up to eight instruments playing simultaneously) can be assembled into Song Steps. In assembling songs, you can define the number of repetitions of each sequence that comprises a song step. This makes it relatively easy to score and arrange a song.
Sequences depend on having instruments loaded into one of the eight instrument banks in the right order. Banks of instruments can be saved which can be loaded in by a song sequence so that loading the song loads all the appropriate sounds into the right places so everything will play when you start the sequencer. In the EPS-16 Plus, an effect is also assigned to a bank.
The EPS supports polyphonic-aftertouch on its 61 keys, and therefore allows a fair amount of expression as a MIDI controller. Sys-ex messages are supported over MIDI, and can transmit and receive on multiple MIDI channels simultaneously.
By using a dedicated sound engine in addition to the main processor, sound generation and disk I/O are handled separately. This allows so-called load-while-play, a feature quite unique at the time. The user can boot the EPS and load some sounds while playing the ones that are already loaded. Then sample in a new sound, only to find that you're out of floppies to save your new sample to — the EPS OS will allow you to go ahead, format another floppy disk, and save your new sound without the system function getting in the way of playing the audio.
True to their user-oriented approach, the EPS boot disk not only contains everything needed to run the sampler, but also a tiny operating system with the ability to create a bootable version of itself. This was an improvement on the earlier Mirage sampler, which required a special boot disk with a formatting program, and could not make copies of its own boot disks.

The Ensoniq Mirage is one of the earliest affordable sampler-synths, introduced in 1984 as Ensoniq's first product. Introduced at a list price of $1,695 with features previously only found on more expensive samplers like the Fairlight CMI, the Mirage sold nearly 8,000 units in its first year - more than the combined unit sales of all other samplers at that time. The Mirage sold over 30,000 units during its availability.
Ensoniq Corp. was an American electronics manufacturer, best known throughout the mid-1980s and 1990s for its musical instruments, principally samplers and synthesizers.
The Korg Triton is a music workstation synthesizer, featuring digital sampling and sequencing, released in 1999. It uses Korg's "HI Synthesis" system and was eventually available in several model variants with numerous upgrade options. The Triton became renowned as a benchmark of keyboard technology, and has been widely featured in music videos and live concerts. At the NAMM Show in 2007, Korg announced the Korg M3 as its successor.
Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but was an early Music Workstation. Although its voice generation is typically subtractive in much the same fashion as most analog synthesizers that preceded it, its 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.
Kurzweil Music Systems is an American company that produces electronic musical instruments. It was founded in 1982 by Stevie Wonder (musician), Ray Kurzweil (innovator) and Bruce Cichowlas.

The Emulator is a series of digital sampling synthesizers using floppy-disk storage that was manufactured by E-mu Systems from 1981 until 2002. Although it was not the first commercial sampler, the Emulator was innovative in its integration of computer technology and was among the first samplers to find widespread usage among musicians. While costly, its price was considerably lower than those of its early competitors, and its smaller size increased its portability and, resultantly, practicality for live performance. The line was discontinued in 2002.
The Emax was a line of samplers, developed, manufactured, and sold by E-mu Systems from 1986 to 1995. Sold alongside their more expensive Emulator II and III samplers, the Emax line was conceived after the release of the Akai S-612 and Sequential Prophet 2000, and was designed to compete for the lower end of the sampling market.
The Yamaha Motif is a series of music workstation synthesizers, first released by Yamaha Corporation in August 2001. The Motif replaced the EX series in Yamaha's line-up and was also based on the early Yamaha S series. Other workstations in the same class are the Korg Kronos and the Roland Fantom G. The series' successor is Yamaha Montage, released in 2016, followed up by the Yamaha Montage M in 2023.
The discontinued Roland MC-909 Sampling Groovebox combines the features of a synthesizer, sequencer, and sampler, with extensive hands-on control of both the sound engine and the sequencing flow. It was intended primarily for live performance of pre-programmed patterns consisting of up to 16 tracks of MIDI data. It was released by Roland Corporation on October 8, 2002. This product was announced at the AES Fall Convention in 2002. It is the direct successor to the Roland MC-505 and is the predecessor to the Roland MC-808. Which eventually ended the "Groovebox by year 2010" line of products by Roland which began in the year 1996 with the Original Roland MC-303 groovebox. The Roland Groovebox began again resurgence in the year 2019 with a two new modern & redesign Roland MC-707 GROOVEBOX/Roland MC-101 GROOVEBOX. The Roland MC-909 was developed from the blueprint of Roland's own "Roland Fantom-S Workstation & Roland Fantom-X Workstation" and uses the same structure and operating system, with some differences regarding the Patterns section, not implemented in the Roland Fantom S/X6/X7/X8 Workstation.
The Akai S3000XL is a sampler with 32 polyphonic voices, and 2 MB of built-in RAM.
The Ensoniq TS-10 was a synthesizer and music workstation introduced by Ensoniq in 1993. It provided synthesis, user sample playback, sequencer, effect units and performance facilities in a 61-key package.
The Ensoniq VFX Synth was initially released as a performance type synthesizer in 1989. It was soon followed by the release of the VFX-SD, which included some updated waveforms, a 24-track sequencer and a floppy drive. Both models were equipped with the Ensoniq Signal Processing (ESP) chip for 24-bit effects. The VFX-SD also included two AUX outs, which allowed for a total of 4 outputs from the synth for more routing flexibility. The initial models were 21-voice polyphony, and in latter models of the VFX-SD (I/II) and the SD-1, the polyphony was 32.
The Korg DSS-1 is a polyphonic sampling synthesizer released by Korg in 1986. As Korg's initial entry into the sampling market, the DSS-1 combines sampling, additive synthesis, and waveform drawing with an analog signal path. The DSS-1 was released a time when major synthesizer manufacturers like Yamaha and Casio were beginning to explore sampling, an area of sound design dominated by companies like Fairlight, E-mu, and Ensoniq. Korg did not stay long in the sampling arena; the DSS-1 was the company's only sampler until 1998 when Korg introduced sampling options on their Triton and Trinity series of workstations.
The Ensoniq SQ-80 is a digital/analog synthesizer manufactured from 1987 to 1989. It was Ensoniq's update to its first synth, the Ensoniq ESQ-1.
The Ensoniq ASR-10 is a sampling keyboard produced by Ensoniq between 1992 and 1998. The ASR-10 was a follow-up product to the very popular Ensoniq EPS and EPS-16 Plus performance samplers, and was also available with a piano style weighted keyboard (ASR-88) and a rackmount version (ASR-10R). At the time, the machine was one of the most powerful samplers available.
The Roland W-30 is a sampling workstation keyboard, released in 1989. It features an on-board 12-bit sampler, sample-based synthesizer, 16-track sequencer and 61-note keyboard.
