Keytek CTS-2000 Cross Wave examples

Published on Apr 29, 2013

"Here are several examples of single oscillator waveform crossfades. The Keytek CTS-2000 can crossfade between 3 waveforms per oscillator, with a 2 stage envelope (two times and an intermediate breakpoint) for each crossfade. The IC responsible for this is the SGS M114S, which was also used in the Cheetah MS800, Amstrad CKX100 and Solton K160, as well as the other Keytek models (CTS-1000G, CTS-400, CTS-5000) and some obscure pinball machines.

Update via acreil in the comments: "I have a writeup on the CTS-2000 that I can publish soon, once I do some editing. Until then I'd like to suggest this as a more appropriate demo: http://www.youtube.com/watch?v=yiwrJzeDGYg"

Keytek CTS-2000 (Inoyama Land - Shuffer)

Uploaded on Nov 5, 2011

"Arrangement of Shuffer by Inoyama Land, using multitracked Keytek CTS-2000 (rare wavetable synth, now sold). I had modified it some to make the sound brighter. Reverb added in Pure Data (my own algorithm). I just played along to the original rather than use a click track or sequencer. It came out a little messy, but I think it suits the composition. Recorded 2011.

"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."

Weird Obscure Lo-Fi Synthesizer Meets Noisy Obsolete FX Rack 🎹 Keytek CTS-2000 and Roland DEP-5

video upload by Reuben Jones

"The 1987 Keytek CTS-2000. A cool, quirky, lo-fi wavetable-style synthesizer from Italian brand Keytek, formerly known as Siel before being bought by Gibson USA....(!) Run through a 1984 Roland DEP-5 digital chorus/reverb.

All sounds made using the Keytek CTS-2000 and Roland DEP-5 Effects Processor.

Low-res voxel models made in MagicaVoxel."

Keytek CTS 2000

Two sites sent my way via swissdoc:
cts2000.html
m_keytek_e.htm

"The Keytek line was an attempt at reviving Siel around 1987. There were several models produced, the CTS-1000 (boring 8 voice synth, preset only), CTS-2000, CTS-5000 (piano-style keyboard), CTS-400 (4-octave keyboard, similar to CTS-1000?), and at several home keyboards (I know of the K-50 and K-60, perhaps there were more). As far as I can tell, the CTS-2000 is the only interesting model. The Keytek line didn't last long, as Siel went out of business and was bought by Roland. It's a fairly ugly synth, Obviously influenced by the DX7 design with membrane buttons and nasty 80's colors accenting its gray case. And it's fairly heavy considering the case is plastic."

KEYTEK CTS 2000 TRANSWAVE Synthesizer w/ Analog Filters

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

You can find a few demos of the KEYTEK CTS 2000 in the archives.

"The CTS 2000 is a sound designers dream taking the Transwave wavetable concept such as the Ensoniq Fizmo and comes with a hybrid of wavetables and analog resonant CEM filters like the Waldorf Microwave 1.

If you're into ambient atmospheric and organic sounds or a hybrid of between the two this synth is an undiscovered gem! Think Boards of Canada meets Aphex Twin with those digital textures warping into the gritty analog filters. Comprised of 8bit waveforms there's two oscilators per voice with eight voices and plenty of envelopes to mix and manipulate 8bit waveforms into one another.

The synth needs time and patience, look beyond the presets! Once you start manipulating the and storing sounds you begin to see the true extent of how powerful a synth this really is.
Its not for the faint hearted plug and play producer, but once you start using it the controls and parameters are straight forward.

With 333 digitally sampled waveforms. You can control up to 6 wavetables per voice with complete analog processing for each voice including 24db per octave filter. 2 envelope generators with up to 5 parameters and 3 LFO's. 6 data entry slider for real time editing of all parameters"

Siel CTS-2000, just a few sounds passing by...

Published on May 26, 2019 [ጠσσǥǥሃ]

"Another rare and atypical machine: the Siel CTS 2000. (Usually called Keytek)
Italian hybrid synth from 1987, using sort of wavetables...
A mix of Ensoniq and PPG Wave, under an Emulator II/DX7 interface!
It sounds really weird, and it's pretty complicated to use :)
Wavetables are generated by 2 really cheap SGS M114A, and the filters are CEM 3389 (Sequential Circuits Prophet VS, Studio 440, Waldorf Microwave 1, Ensoniq Esq-1, SQ80...)
The whole thing runs under a TMS-7002, that is almost enough powerful to make transients (Often goes not smooth and sometimes there are 'Plops' in the sound)"
