The E-mu Proteus was a range of digital sound modules and keyboards manufactured by E-mu Systems in the late twentieth century.
E-mu Systems came to prominence in the early 1980s with its relatively affordable Emulator sampler, and subsequently pioneered sample-based synthesis technology with the Proteus range. Unlike earlier types of synthesisers, sample-based equipment does not derive its raw sounds from electronic oscillators or algorithmically generated waveforms, but from recorded sounds held in read-only memory (ROM) chips. These sounds may then be layered, filtered, modulated by low frequency oscillation and shaped by ADSR envelopes. However, unlike a true sampler, such devices do not allow the user to record sounds but instead offer a range of factory sounds suitable for any given use. This type of sound production dominated electronic music production for several years in the late 20th century. The exclusive license for re-formatting and managing historical E-MU Proteus sound content has been acquired by Digital Sound Factory.
The original Proteus series are basic ROMplers which contains 3 base models with 192 patches each, of which 64 are editable by the user. The patches have an assigned sample and allow basic ADSR editing, and it's possible to link more than one patch together for a richer sound. The units have 32 voice polyphony.
The Proteus 1 contains general sounds from the Emulator library useful for music production, the Proteus 2 specializes in orchestral sounds, and the third model in sounds for world music. Additional versions include the following:
 | Proteus 1 Pop/Rock (1989) |
| Proteus 1 XR (1990) | |
| Proteus 1 Plus Orchestral (1990) | |
| Proteus 2 Orchestral (1990) | |
| Proteus 2 XR (1990) | |
| Proteus 3 World (1991) | |
| Proteus 3 XR (1991) | |
| Pro/Cussion (1991) | |
 | Proteus FX (1994) [1] |
The second generation of E-MU ROMplers added a filter.
| Vintage Keys (1993) | |
| Morpheus (1993) | |
 | UltraProteus (1994) [2] |
 | Planet Phatt [Hip-Hop] (1997) Orbit [Techno/Electronica] (1996) |
| Canvanal [Latin] (1997) |
The Proteus 2000 released in 1999 was a 1U rack sound module based on Audity 2000 released in 1998. It contained many "bread and butter" sounds, [3] among just over a thousand waves utilising 32 megabytes of ROM. It featured up to 128 voice polyphony and 32-part multi-timbrality. [4] It could be expanded with slots for three additional sound ROM cards. A cheaper Proteus 1000 model was also introduced with the same soundest and ROM but only 64 voice polyphony and fewer individual sound outputs. The Proteus 2000 also has Protozoa ROM expansions that contain patches from the original Proteus trilogy, where the first 128 patches towards each of the three modules respectively were faithfully re-mastered digitally from scratch that could be purchased to add onto the module, consisting a total of 384 patches of up to 16 MB of memory.
The Proteus 2000 range also consisted of several specialized models, some differing from each other only by the sound banks they contained. However, most allowed four ROM chips to be mounted, and these chips were available separately, so real differences might be simply cosmetic. The available ROM chips included the Composer, a work-horse set of sounds useful for popular music production, three orchestral ROMs, the Vintage Keys collection of electric organs, pianos and classic synthesisers, a chip dedicated to the Hammond organ and a drum ROM as well as the Orbit and Mo-Phatt collections, aimed at dance and urban genres and the Xtreme Lead, optimised for monophonic synthesiser soloing. Most of these were also sold as specialized modules, even though the hardware inside most of there is virtually identical to the Proteus 2000.

This 4U rack model was designed to function as a rack-mounted, front-panel-programmable sound source. It was equipped with sixteen multi-function pads and the same number of programmable knobs and had an onboard sequencer.
In 2001 the Proteus line of modules was repackaged in the form of a line of tabletop units, the XL7 and MP7 Command Stations, broadly similar to the rack-mounted 2500 in features but featuring touch-sensitive pads suitable for recording drum patterns.
In 2001–2002, E-mu/Ensoniq released a trio of entry-level keyboards, essentially the keyboard versions of the Proteus 2500 module. The E-mu MK-6, XK-6, PK-6 and Ensoniq Halo featured the same 61-key keyboard and controls layout, but slightly different soundset.

Since Creative withdrew their provision of historical OS updates and manuals for most of the older E-Mu gear sometime around August 2011, [7] many of these files have been made available elsewhere, such as Synth Gear Docs Archive and the E-Mu Legacy Archive.
Mark Snow used the Whistl'n Joe instrument patch (Patch #125 on the Proteus 2) for The X-Files theme. [8] [9]
Eric Serra used the Infinite One instrument patch to get the sharp, metallic percussive sound that is featured in his soundtracks, such as in The Fifth Element , Leon the Professional , and GoldenEye . [10] Subsequently, the video game composer Graeme Norgate [11] would use the same patch in games such as GoldenEye 007 and Perfect Dark . The sound originally is from a tambourine, pitched down, and treated with delay and reverb effects.

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 Roland D-50 is a synthesizer produced by Roland and released in April of 1987. Its features include digital sample-based subtractive synthesis, on-board effects, a joystick for data manipulation, and an analog synthesis-styled layout design. The external Roland PG-1000 (1987) programmer could also be attached to the D-50 for more complex manipulation of its sounds. It was also produced in a rack-mount variant design, the D-550, with almost 450 user-adjustable parameters.
Novation Digital Music Systems Ltd. is a British musical equipment manufacturer, founded in 1992 by Ian Jannaway and Mark Thompson as Novation Electronic Music Systems. Today the company specializes in MIDI controllers with and without keyboards, both analog and virtual analog performance synthesizers, grid-based performance controllers, and audio interfaces. At present, Novation products are primarily manufactured in China.
A rompler is an electronic musical instrument that plays pre-fabricated sounds based on audio samples. The term rompler is a blend of the terms ROM and sampler. In contrast to samplers, romplers do not record audio. Both may have additional sound editing features, such as layering several waveforms and modulation with ADSR envelopes, filters and LFOs.
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.
The Ensoniq MR61 is a 61-key music workstation synthesizer that Ensoniq released in 1996. It features a 16-track sequencer, digital effects, and several hundred onboard sounds or patches.
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 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 Ensoniq Fizmo was Ensoniq's last attempt at creating the perfect synthesizer. Developed in 1998, the Fizmo uses a Digital Acoustic simulation Transwave with 4 MB of ROM, up to four voices per preset, each voice with two oscillators, independent LFOs and FX: 48 voices maximum, with three separate fx units built in for further sound sculpting. The Fizmo featured 61 keys, and responded to velocity, channel aftertouch, as well as allowing the sounds to be split by velocity and keyboard position (note). The name F-I-Z-M-O was mapped across five control knobs just above the keyboard keys, allowing real-time modulation of the waves for more user controlled evolving sounds than a usual synthesizer could provide, as well as also having 17 dedicated Sound and Effect editing knobs for further sound design and editing.
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 Yamaha SY99 is a synthesiser combining frequency modulation synthesis and sample-based synthesis and the direct successor to Yamaha's SY77/TG77. Compared to the SY77, it has a larger keyboard at 76 keys instead of 61, a larger ROM with more in-built AWM samples, the ability to load user-specified AWM samples into on-board RAM, an upgraded effects processor, and several other enhanced features.
E-mu Systems was a software synthesizer, audio interface, MIDI interface, and MIDI keyboard manufacturer. Founded in 1971 as a synthesizer maker, E-mu was a pioneer in samplers, sample-based drum machines and low-cost digital sampling music workstations.
The Sirius is a keyboard "groove-synth," featuring a subtractive hybrid-tone-generation synthesizer referred to as DTE synthesis introduced in 1997 by Quasimidi. The unit featured both real-time and step sequencers with pattern- and song-modes, capable of acting basic drum machine, groove-box, or sound-module.
The Roland MKS-80 Super Jupiter is a rack mount sound module version of the Roland Jupiter-6 and the Roland Jupiter-8 synthesizers. It is an 8-voice polyphonic analog synthesizer that was manufactured by Roland between 1984 and 1987. It is the only one of the MKS series of synthesizers to have analogue voltage-controlled oscillators (VCOs) instead of analogue digitally-controlled oscillators (DCOs). The voice architecture is almost identical to the Jupiter-6 synthesizer. The service manual states that "The module board of MKS-80 features the following in addition to that of JP-6, its brother module. 1) HPF. 2) Low boost circuit in the 2nd VCA. 3) DC supply current boost circuit (IC50)."

The CZ series is a family of low-cost phase distortion synthesizers produced by Casio in the mid-1980s. Eight models of CZ synthesizers were released: the CZ-101, CZ-230S, CZ-1000, CZ-2000S, CZ-2600S, CZ-3000, CZ-5000, and the CZ-1. Additionally, the home-keyboard model CT-6500 used 48 phase distortion presets from the CZ line. The CZ synthesizers' price at the time of their introduction made programmable synthesizers affordable enough to be purchased by garage bands. Yamaha soon introduced their own low-cost digital synthesizers, including the DX-21 (1985) and Yamaha DX100, in light of the CZ series' success.
The Akai SG01v is a ROMpler, meaning that it plays prerecorded samples stored on a ROM chip, as opposed to generating sound through onboard signal generators. The unit was produced by Akai in 1995. It is housed in a 1U half-rack chassis and can be controlled through General MIDI messages. The SG01v has 32 voice polyphony and 16 part multi-timbrality. Considering the technology of the day, the SG01v reproduces with surprising fidelity the sounds of even older analogue synthesizers, as well as two drum kits. The "V" designation in the model name denotes "vintage" sounds. The model line also includes an SG01k, which was strictly a General MIDI module, and an SG01p.
