TECH Main core based on H8/3002 family (16/32bits) + dedicated audio DSP ADSP-2185 - Analog Devices. XP2 synthesis is based on VA physical modelling generates 8 voices polyphony, DAC is based on Analog devices AD1881A.
An unused socket labeled "software conversation socket" probably for "conversation kit" the vocoder.
STRUCTURE 2 detunable oscillators per voice:
- OSC1: progressive from saw to square waveform with variable width.
- OSC2:
is much more complex with same progressive OSC1 waveform plus two special modes:
formant + sinewave mode.
Oscillators can be ringmodulated in this way: OSC1 > OSC2
Also a noise generator with 3 colors pink/ white/ blue.
PERFORMANCE the 8 voices polyphony can be assigned to 5 parts each with individual settings:
|
- keyboard
zone assignment
-
Midi channel
-
panning stereo
-
gain volume
-
pitch transpose
- monophonic mode (8 glide modes)
- aftertouch to filter
- aftertouch to LFO |
VECTOR the joystick can be used to control different parameters in real-time:
|
-
vector mode mixes between volumes section -
filter cutoff and resonance amount
-
ringmodulator ratio
ringmod |
FILTER digital 2-poles resonant filter features 3 modes: lowpass, highpass and bandpass.
Special keyboard filter tracking at 25, 50, 100, 150%.
ENVELOPE up to 2 EGs with quite free routing:
|
EG1 |
EG2 |

LFO up to 2 interchangeable delayed digital modulators (shapes: ramp, triangle, square, sine, pulse, sample-hold and random). Modulators can be retriggered at notes, synched to external Midi clock at various dividers from 1/8th beat to 4 bars.
LFO Destinations are:
|
- OSC pulse width
- OSC amplitude
- OSC pitch
- stereo panning
- filter resonance
HEAR LFO |
EFFECT a digital chorus is included with variable rate/depth.
MIDI all parameters are mapped to Midi CC# and the knobs transmit also this controller.
MEMORY
- 64
RAM slots.
Patches and performances can be only saved to Midi exclusive dump.

EDITOR not much softwares has been released for this module but the "Dark Star Editor".
RELATED FAMILY:
|
Darkstar classic MK1- first version version with different design.
mk1 vs XP2 differences: Mk1 features RCA instead of Jack, no headphones, lacks the chorus and special SINEWAVE mode (for OSC2).
