Emu Proteus /1 (1989)
16 bit Multi Timbral Digital Sound Module

 

First module rompler produced by famous American sampler company EMU.
An affordable collection of bread and butters pop sounds from Emulator III archive.

The proteus series do not have filter, which is now a pretty big miss.

info RACKMOUNT MODULE 1 rack unit mainly made out of plastic.
Main panel features a 16 x 2 LCD display, 1 volume knob, 1 data encoder and 4 push buttons.

Rear panel terminal connectors:
- main signal out
- 4 individual outputs (subs with possible external insert)
- Midi interface
- VDC power.

 

 

edit VOICE main core based on a Motorola MC 68000 manages up to 32 channels polyphony with six 16 bits PCM56P DAC. A voice is composed by 2 PCM elements samples "primary" and "secondary" with some edit parameters:
- pitch tuning (fine and coarse)
- keyzone assignment
- start delay
- stereo panning
- mix level
- reverse playback
- chorus mode (it thicks voice).

edit WAVETABLE internal 4Mb ROM (8 X rom ICs) 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:
- XR: extra RAM adds 192 new slots
- Plus Orchetral extra rom adds 4 MB of orchestral sounds (same found on PROTEUS 2 module)
- Invision Protologic third part board with 4MB extra ROM.

PERFORMANCE up to 16 parts with 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
- scale tuning 5 presets (equal, vallotti, just C, 19 tone, gamelan) + 1 user free.

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 standas for: Delay, Attack, Hold, Decay, Sustain, and Release). Special "Alternate" mode plays the EG forward and then Backward.
- EG primary sample amplitude
- EG secondary sample amplitude
- AUX (assignable) EG can be assigned to the matrix control (see below)
In addition 4 preset velocity curves.

 


edit MIDI
full sysex commands and some basic CC controls including: panning, modulation and 4 assignable controllers ABCD (see "matrix" below).

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

MEMORY:
- 128 ROM patches
- 64 RAM slots
Sounds can be saved only using Midi sysex, no external medias.
Battery replacement: soldered Lithium BR2-3 3V battery (see picture below)

edit MODIFICATION
and MAINTENANCE I attempted to mod it with a circuit bending, but no great results, some exemple audio clips in the DEMO section


circuit bending

2 common issues:
- DISPLAY:
is not uncommon to split dead black zones on the display.
- ENCODER:
after some times the encoder may go berserk just clean it with Q-tip and dedicated liquid product.

lcd dark rotary encoder
Display seems to get dark in some corners Encoder simply skips values and needs cleaning

REVIEW : "Proteus is getting too old: no filter, no effect, limited synthesis enclosed in a cheap plastic. The Proteus 1 still have some decent 80 pop sounds- if you care"
