Keytek MDP 40 Midi Digital Drum Machine

This one was spotted and sent in by swissdoc.

You can find an overview video of the RMP 40 branded version posted here.

via this listing

"This is a very desirable VINTAGE, FULLY FUNCTIONAL classic drum machine from the 1980's (released in 1986), the SIEL MDP-40...also known under other brands as the SUZUKI RPM-40 and the KEYTEK MDR-40. It was made in Italy, and features 10 pads for 13 PCM sounds, 3 of which are accessible by external MIDI only. This machine comes with original power supply and owners manual. The unit itself is a desktop model, has LED display, is lightweight (only 1 kg), will also operate on 6 x AA batteries, and has 3 MIDI ports. Audio output is via 1/4" phone jack, mono out. I hate to let this go, but I haven't taken the time to experiment with it in recent years as I had hoped to do, so I'm passing it on. I envision it to be very useful in live performance situations as a trigger machine MIDI'd to a more modern drum machine with tight, up-to-date drum/percussion sounds."

P.S. Moby owned one.

"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."

KEYTEK CTS 2000 TRANSWAVE Synthesizer w/ Analog Filters

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

via this auction

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"
