Emu Proteus MPS - model 9030 (also 9031 expanded)

Early keyboard version of the famous module Emu Proteus 1 adding a special FX DSP section

The Proteus series do not have filter - which is pretty big miss.

infoKEYBOARD 61 keys with velocity and aftertouch. Main panel features a 16 x 2 LCD display, 30 push button, 1 volume slider and 1 data encoder.

Rear panel terminal connectors:
- main signal out
- Midi interface
- headphones
- 1 pedalswitch input (e.g. SUSTAIN)
- 1 pedal input (e.g. VOLUME).

Front panel terminal connectors:
- headphones.

info POWER SUPPLY: is quite weird with custom connector DINS (18V AC) DO NOT get a MPS without the PSU.

 

 

edit TECH main core based on a Motorola MC 68000 manages up to 32 channels polyphony.

STRUCTURE A MPS voice is composed by 2 elements samples called "primary" and "secondary" with some edit parameters:
- pitch tuning (fine and coarse)
- keyzone assignments
- start delay
- stereo panning
- mix level
- reverse playback
- chorus mode (it fats voice up).

edit WAVETABLE internal 4Mb ROM - 125 PCM waves at 39 kHz / 16 bits resolution.
PCM wavetable contains all kind of sounds samples including: piano, string, sax, trumpet, brass, guitar, bass, organs, drums, percussions and basic waveforms (digital, square, harmonics, short-cycled).

edit EXPANSION some different upgrades were available:
- Plus extra rom adds 4 MB of orchestral sounds (same found on PROTEUS 2 module)


plus orchestra


edit PERFORMANCE multitimbric system up to 16 parts some special functions:
- solo monophonic mode (for OSC1/OSC2/BOTH)
- crossfade balance between primary and secondary
- pitchbend range (+/- 1 OCT)
- 3 footswitch assignable controls (eg: sustain, portamento, hold...)
- key velocity control
- FX amount
- Quickeys function: enable a special 4 patches setup recall with zone assignment
- Keyboard Split zone.

edit LFO 2 delayed modulators (shapes: sin, triangle, saw, square and random) for pitch with variable amount and random fluctuation.

edit ENVELOPE there are 3 EGS .
Structure : 4 segments + 2 times called DAHDSR which stands for Delay, Attack, Hold, Decay, Sustain, and Release. Special "Alternate" mode plays the EG forward and then Backward.
- EG1 primary sample amplitude
- EG2 secondary sample amplitude
- EG3 AUX (assignable) EG can be assigned to the matrix control.
In addition 4 preset velocity curves.

 

 

edit EFFECT unlike the previous rackmount, MPS features a double DSP engine for effects A/B:
A- REVERBS: delay, reverb (plate, chamber, hall, warm), stereo chorus, EQ, echo.
- VARIOUS: flanger, chorus, phaser, fuzz, ring modulator, cross delay, EQ.

 

 

edit MIDI full sysex commands and some basic CC controls including: panning, modulation and 4 assignable controllers ABCD (see "matrix" below).
TECH: for some stupid reasons, the MPS is not fully compatible with Proteus 1 patche for different bank strucure 1-100 vs 1-127.

the "real-time control" allows some special modulation routings:

MEMORY:
- 100 ROM patches
- 100 RAM slots.
RAM 256 KB S-RAM doubled if memory card fitted.
Sounds can be saved only using Midi sysex, no external medias.
Battery replacement: soldered Lithium BR2-3 3V battery.

REVIEW "Bit old sample wavetable and no filter section. The fx section is a nice feature compared to previous Proteus module. Beware of some possible issues with keyboard, psu and display."
