Siel DK 80 Synthesizer Keyboard

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"According to an expert I found on a forum online...The Siel DK-80 is an odd synth that could be said to bridge the gap between low end mid-eighties Roland and Sequential type synthesizers. It is an analog synth with digital control. It is also bi-timbral with a split keyboard mode giving you 2 polysynths in one keyboard! The sounds are OK, and the DK-80 makes a great backup synth. It has an on-board two-track sequencer, chord memory and hold, programmable stereo panning and sweeping. Parameters are edited one at a time and via membrane push buttons. For a fair price the DK-80 is certainly an exotic addition to any synth set up but may be too limited to use as your main or only analog synth."

"The Siel DK-80 is a bi-timbric, polyphonic synthesizer with voice assignment containing 12 complete and individual synth modules (termed voices or channels). It is fully programmable and able to store up to 50 programs in its computer memory and groups of 50/100 programs in the RAM/ROM packs.(additional mem.), which can be inserted into the special Cartridge location. The instrument is provided with 12 oscillators (DCO), 1 pink noise generator, two 24db/octave low pass Voltage Controlled filters (VCF), 14 digital envelope generators(DEG) and 4 low frequency oscillators (LFO), providing a parallel modulation of parameters such as pitches and filters. All this is controlled by specific controls on the EDIT section and memorized in the heart of the DK-80; the Programming Unit. The Programming unit also controls the 50 factory programs (40 not programmable and 10 programmable) and the 50 or 100 external programs: 50 (programmable) on a RAM pack, or 100 (not programmable) on ROM pack. Thus the DK-80 can control up to 150 musical programs simultaneously; 50 internal ones plus 50 (on RAM) or (ROM) external ones which are recalled directly by the Programming Unit."

Siel DK-80 with filter mod and knobbified with BCR-2000

YouTube Uploaded by taigkyo on Aug 17, 2011

"Simple goof-off demo of a knobby solution for the DK-80 using BCR2000 while playing back a MIDI file. There are no effects on the DK-80; this is recorded straight in one pass with a faint loop in the background from the CD (Fade to Grey) :-) The DK80 is an 80's splittable/stackable analog polysynth with patch memory and MIDI. It has a very unique sound due to two 4-pole (24dB/octave) SSM filters (like Emu Emulator II, early Prophet 5, Fairlight CMI II, Korg Poly-6/Monopoly, PPG Wave 2.2/2.3, Kawai K3/SC240, Simmons SDS5 etc), four LFO's, and two 6-point EG's (normal ADSR is 4-point. . . this adds a couple more points for more complex/evolving sounds). Perhaps the DK80 is deservedly underrated for being a PITA to program, but with knobs a whole new world opens up."

Siel DK-80 Test

Published on Jul 20, 2014 Pizza Synth

"Here is a demo of the Siel DK-80 to show working condition for sale. Midi/chords are coming from Ableton. Touch of Alesis Midiverb 1 on the master. I change the programs once in the beginning of the video and then tweak a few basic parameters. Cutoff and Resonance, etc, and then just detuning a bit. I run through the keys, velocity, and play a chord to show all voices firing at the end."

Some vibraphone music on the Siel DK-80

"It has been a while since I used my Siel DK-80 synthesizer. But now I have made this little MIDI piece featuring a vibraphone-like sound.

The rhytm comes from my Roland JV-35."

"Dig og mig" - on Siel DK-80

YouTube via organfairy — April 29, 2010 — "'Dig og Mig' ( = You and me) was originally recorded in the mid 1980's by Danish one-hit-wonders "Dieters Lieder". Here I play it in multi track on the Siel DK-80 synthesizer and Korg Rhythm 55 drum machine.

Rumour has it that Dieters Lieder broke up because they couldn't get air time on Danish television. It might seem odd today where anyone can get their 15 minutes of fame - and maybe even more - on the internet. But in the 1980's television was the number one media when it came to gaining stardom if you were a singer or musician. In countries with only one TV channel - like Denmark was at that time - the head of music department at that one channel could therefore literally singlehandedly decide who was going to be famous and who would forever stay in oblivion.

The reason this song became a hit was because it was included in the soundtrack of a popular comedy series that Danish television bought from an independant film production company."

Siel DK 80 Synthesizer Rare Italian 2 DCO Synth SSM chips

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

This is the one in this video.

"Up for sale is a Siel DK-80. It's an Italian, 2 DCO synth, analog with digital controls, from 1985. Cosmetically rough condition because one of the plastic ends is cracked, and the door for the ram cartridge is loose. Its attached it just doesn't hold itself open. Other than that the case has the normal scuffing, scratches etc, for a synth this age. The cracked side is not pretty but the fully functional. I did not program the sequencer as I didn't have time to learn/get the manual. But all keys work, velocity works, all parameters adjust, midi is functional, all voices play, and it is in tune.

It's also bi-timbral with a split keyboard mode, has an on-board two-track sequencer, chord memory and hold. Parameters are edited one at a time and via membrane push buttons. See the demo below for an example of that. The presets are pretty basic but I really like this over similar DCO synths once you play with the filter and resonance a bit. VCF section uses SSM chips. Emu’s Emulator II also uses these chips. Midi CC’s are all available online and mappable to your fav knobby controller."

Keytek CTS2000 Cross Table Sampled Synthesizer SN 0279

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

You can find a couple of videos featuring the CTS2000 in previous posts here.

"THE GIBSON Synthesizer. The only.

Its name: The Keytek CTS 2000
Analog True vintage : CURTIS CHIPS // CEM 5530 / 8 CEM 3389
Released in 1987.

RARE COLLECTOR Early Model number 279

This will be supplied with :

1 COMPLETE IN ENGLISH !! Instruction Manual ! 64 pages
1 EXTERNAL ORIGINAL MEMORY CARD of this KEYTEK CTS 2000 model to store even more of your sounds.
1 CASE
1 OLD ORIGINAL ADVERTISEMENT

Fender has also released one on its side: The Chroma Polaris.

Story : Gibson had bought the Italian brand SIEL (Societa Industrie Elettroniche)
and worked in collaboration with its engineers who had already released
a lot of synthesizers including ( Cruise, Orchestra, Orchestra 2, Dk-70,
Ex-80, Dk-80 , Expander , Opera 6 , Dk-600 , Dk-700 , Kiwi ) and worked
themselves with suzuki and knew how to draw inspiration from analogs
from Korg .Moreover it would have been produced in Japan.

Gibson's synth, the Keytek CTS 2000 is a 330 plus wavetable based
synthesizer. But it is above all one of the last analog synths of this era. For
this it was equipped with Curtis chips, the same used in the little brother
of the Waldorf Wave, the Microwave .... as well as the Prophet 2000 which
is a Sequencial Audio / Dave Smith sampler ...

It has 6 voices with 2 oscillators per voice.
7 levels of envelope settings...
A Total MIDI Implementation....
An internal memory to save 48 sounds.
Finally its specialty of Cross Table Sample allows to mix for a sound of the
wavetables between them to obtain a combination of 330 X 329 so 9000 !

That is more than 9000 waveforms more than the sinusoid, the triangle,
the square, the sawtooth ! And this for a single voice ....
Each oscillator can be tuned differently for Fat sound .
An Lfo is also present to modulate these.
Dcf
Dca
Cut-off
Resonance
ADSR on 7 levels
All this in many combinations

One cannot simply overcome its possibilities.

It produces a unique sound. With it your instrumentations won't sound too much today.
He will add a personal color. It can produce percussive sounds, particular pads...

Another thing that differentiates the KEYTEK CTS 2000 is that very few copies
were produced in the world.
There are 2 other Keytek models but they are only weakly trimmed compared
to this one.

The model on sale was released in the very First GIBSON-SIEL workshops.

Number 279."
