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.

Keytek CTS 2000

Two sites sent my way via swissdoc:
cts2000.html

"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."

Trip. When I had severe GAS (Gear Aquisition Syndrome), I used to have these dreams where I'd walk into a pawn shop and see all these bizarre and obscure synths. Sometimes they were rare models of Oberheims and Rolands, etc, but usually they were obscure synths from manufacturers I've never seen before. Right before I was waking from the dream, I'd think if I only grab one I might be able to take it to the other side. : ) If you ever had dreams like this you probably know what I'm talking about.

Well, when I saw the Synthmaster post on sequencer.de, I had that same feeling, like I just walked into a pawn shop of obscure synths in dream land. There are a ton of bizarre and obscure synths I've never seen or heard of before. Looks like he brought them over from the other side. Click here for more.
