Emu Ultraproteus (1994)

An updated EMU Morpheus version with different wavetable and filter table.

A one of kind module able to create and morph motion textures with evolving pads.

info RACKMOUNT 1 rack height unit.
The main panel features a 16 x 2 lines display, 8 buttons and a data encoder.

Back panel terminal connectors:
- Midi interface
- main signal out
- 2 assignable AUX

Front panel terminal connectors:
- headphones out
- data card slot.

editVOICE a 16 bits core Motorola MC68020 manages up to 32 voices polyphony, EMU DACS are 6 X 16 bits analog devices AD1860. A basic sound patch is a combination of 2 samples primary + secondary - each with individual parameters:

wavetable - oscillators crossfade osc1-> osc2 / osc2 -> osc2
- stereo panning position
- keyrange
- pitch tune
- monophonic with portamento
- reverse sample play
- loop mode


WAVETABLE the internal 16 MB ROM contains 484 PCM waves at 39 kHz / 16 bits resolution, most of these are from previous Emu Proteus machines.

wavetable The wavetable contains various kind of PCM including: drums, choir, strings, organ, moog bass, guitar, harmonics, piano, basic waveforms and ethno percussions.


playmodes MULTIMBRAL
the 32 voice polyphony can be assigned to hypermode performance mode which manages 16 parts with individual settings:

- volume gain
- stereo panning
- pitchtranspose
- keyboard zone
- velocity offset
- effect amount

filter FILTER
this section features 288 Z-PLANE pre-calculated filters, these are combinations of 20 comb EQ with variable bandwidth parameters. The famous filter Morphing function interpolates 2 selected filter models simply using the modulation wheel control.

morph3 - Primary amp : 4 segments +2 level times
- Secondary amp: 4 segments +2 level times
- AUX assignable: 4 segments +2 level times
Special function generator segments a curve into 8 parts and creates a special motion mode using 64 preset shapes (e.g: linear, exponential or random).

lfo LFO
up to 2 delayed modulators (shapes: triangle, sinewave, square, saw and random). Modulators offer other special parameters such as depth and variance mode which is a natural strings instruments emulation, a kind of natural desynch process.
LFO destinations:

morph3 - LFO to filter cutoff
- LFO top anning image
- LFO to volume
- LFO to pitch tuning.


matrix mod codes every parameters from one the another with many different path routing assignable to Midi CC# - these are really similar on the one found on the EMU samplers like ULTRA series.

there are 28 effects e.g : ring modulation, reverb, shimmer, phaser, delay, echo and fuzz.
