Overview
There are various mirage models:
- DSK-8: exists in 2 different cosmetical versions, the dark grey or the black one.
- DSM-8 is the DSK8 rackmount version
- DSK-1: is the "ultimate" keyboard version featuring a red stripe under the logo.


Voice
main core is based on a Motorola 6809 CPU manages 8 digital voices polyphony.

Structure
an elementary patch is a layer of 2 samples, and each sample has various edit parameters including: wave start, end offset, volume balancing, detune ratio or loop points.

Memory
RAM is split into 2 banks: lower and upper.
Each bank holds 64 Kb data for a total amount of 128 KB, consequently time recording is limited to:
- 2.0 seconds at 33 kHz rate
- 6.5 seconds at 8 kHz frequency

Filter
section is based on 8 X chips CURTIS CEM 3328 with a 4-poles resonant filter.
VCF also features a KEYTRACK function.

LFO
a single triangular modulator, 5 Hz-> 40 Hz frequency range.
The LFO modulates only the oscillator pitch (too bad no filter destination) and it is triggered by 4 possible sources:
- modulation wheel
- breath control
- foot volume pedal
- Aftertouch

Envelope
- EG1 amplitude: 5-segments
- EG2 filter: 5-segments APDSR (P stands for PEAK)


Sequencer really simple and useful for some on-the-fly ideas: basically it is a step sequencer with overdub function that records up to 333 events (it can be a note, a bender or modulation value) or 1024 events if expanded with SXQ-1cartridge. Sequence can be synched to external Midi clock

Storage floppy disk DD 3.5" 400 KB formatted with custom Ensoniq file system format, It is NOT-DOS compatible, but some third-part company softwares read and write floppy disks images. A neat upgrade are the USB devices emulator like HxC or other commercial.

Review
OK: filter / dirty sound
NOT : memory / storage / edit
"It takes time to understand this sampler, but Mirage is an old classic with analog filter"

cool
