SOUND Coldfire-based processor manages 64 digital voices polyphony.
a basic patch is composed by 4 tones PCM samples with independent parameters:
- chorus mode stacks twice the same waveforms
- sample start offset
and delay
- 5 solo modes
- volume
- pitch tuning
- panning
- keyboard zone.
WAVETABLE the factory ROM 32 MB wavetable contains 1210 PCM at 44 kHz- 16 bit resolution. According to EMU company, many XL-1 PCM were directly recorded from the analog vintage machines and modular synthesizers. ROM: wavetable is split in 3 main categories:
1- analog, noise and synthesizer raw waveforms with loops and textures
2- pre-generated harmonics PCM
3-
drum percussions (mainly electronics).

FILTER there are 50 models of Z-plane filters but slimmed down-version from previous Emu Morpheus. First filter types are the classic ones including lowpass, highpass and bandpass and more sophisticated ones like swept octave EQ, phasers, flangers, vocal formant filters. Filters are classified in 9 different categories:
| LPF |
Low-pass filter
|
| PHA |
Phaser |
| HPF |
High-pass filter
|
| FLG |
Flanger
|
| BPF |
Band-pass filter |
| VOW |

| EQ+ |
EQ boost |
| EQ- |

ENVELOPE 3 main EGs sharing same structure : 6 segments + 6 times:
1- EG1: amplitude (1 for each layer)
2- EG2: filter (1 for each layer)
3- EG3: AUX
freely assignable in MATRIX.
LFO up to 2 interchangeable modulators (range from 0,08 Hz to 18,14 Hz) both can be assigned to and open matrix structure (see modulation processor) that manages various sources and modulation destinations. Typical destinations are: pitch, amplitude or filter.
The modulators can be key-synched, delayed and features 17 waveforms:
random
triangle
sine
saw
square
33 / 25 / 16 / 12 % pulse width
hemi quaver
|
pat octaves
pat 5th
pat sus 4th
pat neener
sine 1,2
sine 1,3,5
sine and noise
|
MODULATION PROCESSOR like a huge hardware modular, the XK6 handles 24 internal routings or virtual patchcords that connect a modulation source to a destination. The modulator polarity can be also changed: that is
the value relation that can be set to positive or negative.
A list of the matrix elements would be too long, here's a schematic simplification:
| Sources |
Destinations |

MULTITIMBRAL the global mode manages 16 parts with individual settings:
- Midi channel
- analog out
- panning
- volume
- transpose
- split (link).
EFFECT a 24 bit DSP manages 2 ditable main FX groups:
- DSP1: 44 reverb and echo algorithms including hall, room, plate and delay
- DSP2: 32 modulation algorithms like chorus, flanger, phaser and vibrato.
Full FX list HERE
ARPEGGIATOR each of the 16 global parts can have an assigned arpeggiator (which also outputs Midi).The note/octave range can be assigned as well as velocity gate, latched, looped to specific bars or assigned to 19 different tempo dividers (arpeggio list )
SUPERBEATS included 1024 pre-programmer rhythmic patterns.
These patterns are usually sliced on the keyboards with 2 grooves variations and 4 fills and latch mode; it is also possible to program some user beats using 16 different tracks.
SYNC the internal masterclock from 25 to 300 BPM controls the superbeats, arpeggiator, the LFO frequency or can be clocked to MIDI source.
TIP: the enter button acts as a tap tempo.
MEMORY:
-
512 RAM patches
-
512 ROM patches on the XK6 (XLEAD rom)
- 200 ROM arpeggiator patterns
- 100 RAM arpeggiator patterns
- 12 ROM microtuning
- 12 RAM microtuning
Created sounds can be only saved to Midi Sysex dump.
