E-mu Proteus 2000

The Proteus 2000 is a reincarnation of the economic Proteus rack module series of the early nineties. While its synthesis architecture is virtually the same as the original Proteus, the Proteus 2000 is packed with major new features, sounds and expandability for the most demanding professionals!

It features 128-voice polyphony and 32 MIDI channels allowing it to handle even your most complex MIDI sequences. It ships with a whopping 32 MB of sample ROM memory which is expandable up to 128 MB using four internal ROM slots! The sounds it ships with are called the "Composer" soundset, offering you 1,536 presets (1,024 ROM, 512 user). The sounds cover the whole spectrum of synthesizer type sounds, from real instruments to bizarre sounds and effects.

As seen on previous Proteus modules, there are six individual polyphonic outputs. But unlike its predecessors there are now multi-mode resonant filters (plus 50 Z-Plane filters passed down from the Morpheus and UltraProteus). Plus four real-time controls allow you to access any of up to 12 parameters, giving you instant control over your sounds right from the front-face of the module. The Proteus 2000 is a light, compact module designed for use with sequencers. It can be your main sound module, or one of many. Either way there's an immense amount of great sounds at your fingertips for any music application! A 64-voice keyboard version is available too, the PK-6 Proteus Keys.

Current E-mu sound modules ship with one 32 MB sound-set each, but are expandable up to 128 MB via three additional slots for 32 MB expansion cards. These cards include (ranging from $249 to $395):

  • 9061: Siedlaczek Orchestra 32 MB ROM.
  • 9062: Pure Phatt 32 MB ROM - standard in Mo’Phatt, MP-7 and MK-6.
  • 9063: Beat Garden 32 MB ROM - standard in Orbit 3.
  • 9064: Ensoniq Project 32MB ROM - Containing sounds from EXP-1 Real World and EXP-3 Urban Dance expansion boards
  • 9065: Vintage Collection 32MB ROM - Standard in Vintage Pro
  • 9066: Protean Drums 32 MB ROM - Standard in PX-7
  • 9081: Holy Grail Piano 16MB ROM - From Q-Up Arts, utilizes a new sample processing and preset programming technology called VMS, for Virtual Modeling Synthesis, developed exclusively for E-mu products
  • 9082: Protozoa 16 MB ROM - Containing sounds from the Proteus 1, 2, 3 line.
  • 9083: Definitive B-3 32 MB ROM - standard in B-3.
  • 9084: Techno Synth Construction Yard 32 MB ROM - standard in Orbit 3.

  • 9140: Proteus Pop Collection - Standard in Proteus 2500, contains same 32 MEG sample set as the original E-Mu Composer ROM but has an all new set of 640 preset patches

With these expansion options, you could buy a PK-6, then add the sounds of the Orbit 3, XK-6, and the MP-7... or any other combinations you may want. If you like desktop synths, you can start with an MP-7 or XL-7, and then add these same expansion card options to add Proteus, Orchestral, or the new Halo sounds to them. E-mu/Ensoniq's interchangeable sound cards and a variety of keyboard/sound-module options means that there's a model out there for everybody now.

My daughter has unfortunately hidden the grey knob on the front of my husband's Emu Proteus 2000. Does anyone know where I could buy a spare? Thank you!!

I've created a 9 part series on how to program the Proteus 2000 Synthesizer. This series focuses on creating single (playable) sounds.


It equates the Proteus 2000 to an old analogue synth, using just basic waveforms. I select 36 waveforms in total.

You can create your own sounds just using the front panel, and I help the viewer visualize what effect their programing is having. Series covers the Proteus architecture, envelopes, filter sweeps and stacking sounds (additive synthesis ideas).

Hope this helps!

Hey all!

Proud owner of the Proteus 2000 (loaded with the Proteus 1, 2, 3 and Composer ROM), Planet Earth and Virtuoso 2000. Love 'em. Is there a way to adjust internal volumes in relation to one another? For instance, in the Proteus 2000 kit: Acoustic 2, the snare is very quiet compared to the cymbals and kick drum. How can I turn this up? Any and all help appreciated! Thanks!

I bought a Proteus 2000 new in 2002, and it appears heavily in 4 professionally-released CDs (one of which won an industry award). It is one of my top go-to synths for bass, strings, sine sounds, and lush pads... A problem has cropped up over the past 2 years, however: the data wheel has become chaotic and difficult to navigate with, making my unit almost impossible to use effectively. Apparently this is a common issue. I'll be getting it repaired before embarking on my next project, though, as the benefits of keeping this baby running far outweigh the cost of a small hardware fix.
