SIEL CRUISE VINTAGE ANALOG SYNTHESIZER

via this auction Not the best shots, but you don't see these often.
"Mono Section: About 15 Presets of waveforms combined with fixed filter/ADSR settings. These presets can be changed to some general waveforms ( Mostly Saw ) at different pitches ( from 32' to 4' ). When being in this free mode, the ADSR/FILTER can be accessed in whole. Filter: No Keybord Tracking, no seperate LFO depth, no ADSR depth. Very basic. Early resonance gives wierd effects. There seems to be some low-bit digital control hidden inside. You can hear steps when moving the slider. And you can trick the slider by setting it just on the edge between to steps. Gives great distortion. Sound: Great. Real Basic, big balls, not very flexible. Good for bass and lead-lines. NO CV/GATE !
Poly Section: Octave Divided DCO. Seems to have single Filter with Multi-Trig of single ADSR. 4 Main Presets: Brass, Strings, Piano, Accordion-likes. These Presets are divided in 2 or 3 Tone-Color presets, Mostly high and low, Strings can be percussive, brass can have ( urgh ) resonance (splat). This gives a total of 10 tone colours, which can be combined freely. Main drawback: they can not be mixed seperately. Modifiers: Sort of. There is a small ADSR/Filter section, Some Presets enable some of them, A/D for Strings, A and Cutoff for Brass, and so on. Sound: Gives some mellotronish strings, a fair good piano. and is a bit slim in its sound. 1 DCO.
Keyboard : Number of Keys : 49 . 4 1/2 octaves ( from mind ), fixed split-point in the middle.

Can be split in the middle to have MONO/POLY Section on different keyboard sections. MONO can have Lowest/Highest Note Priority. The syntcan be modified to have all cominations of keyboard-modes accessible, ( for example: UPPER - MONO; LOWER - MONO/POLY )."
