"Rare Japanese 4 channel drum synth – we’re big fans of these. Has separate inputs to trigger each voice and we can mod with separate outputs (see below).
The black variant of the Toyo Gakki DS-4 for sale. This version is almost identical to the blue and yellow “Custom” model, except that the cascade triggering is not present.
Supplied in full working order and covered by our standard 3 month warranty. Currently working well, but will be serviced and will ship within 20 working days of purchase.
Separate Outputs Mod: We can modify the unit with separate outputs for each channel. This will be via the DIN socket on the rear (so no extra holes are drilled) and we will supply a trailing lead with four 1/4″ jack sockets."
"A rare classic hard to get synth, case was a total loss, broken due to elevator transport fault. Full mecanical rebuild into neat 19" rack, front plate redesign. back plate and connectors redesign. New case custom made and special powdercoat same color and finish as the original.
"I've had a dozen requests to cover this synth and I said I'd do it if I was able to get hold of one and I'm glad to say that that happened.
The CS-15 is a two-oscillator analogue monosynth from 1979 that has an awful lot more to it than meets the eye. The signal and control routing is so much more flexible than many other comparable synths from this era that command legendary status and so I'm kind of baffled as to why the CS-15 doesn't seem to be held in the same high regard.
What's so good about it?
Two great sounding oscillators with triangle, sawtooth and pulse and a crazy wide range from clicks to stuff only dogs can hear.
The LFO runs up into the audio range and so the pulse width and oscillator frequency can be modulated at audio rate for cool cross mod and pulse-width distortion FX. This can be done discretely to either oscillator to taste.
The filters - There's two and they're multimode / state variable! Contouring can come from either of the two envelopes and can be positive or negative and you can do audio-rate modulation of the filter because of that LFO mentioned earlier.
The VCAs - There's two (notice a pattern here) and they can have their own envelope contouring and/or be modulated by the LFO (again right into the audio range).
Envelopes - There's (drum roll) two! They're super snappy or long and loose as there's a switch to extend the time period from x1 to x5. They can be triggered by an external signal as well as the keyboard.
Signal Routing - VCO 1, noise or an external signal can run through VCF 1. VCO 1 and VCO 2 can run through VCF 2.
Rear Control - CV and trigger? Yep, there's two of each. You can control the oscillators and envelopes discretely (I don't know of many comparable synths from this era that allow for that that aren't modular).
Anything else? Yes; portamento, glide (positive and negative and discrete for each oscillator), pitch bend and dual or signal filter control in the performance section.
So what's wrong with it?
LFO can't be retriggered with note on or clocked, there's no oscillator sync, the filters sound great but they're 2-pole and don't self-oscillate, there's no global LFO control in the performance section and despite being able to make two entirely different sounds at once, there's only a mono output.
But all in all, it's a very versatile and powerful synth considering its era and the prices have tended to remain less than even the Roland SH-101 which is far more limited. It's certainly much cheaper than an original Pro~One, MS-20 or Odyssey that are held in high regard (I have all of those and love them too btw).
Anyway, I hope this answers the question for those who asked it."
"Video recordings are always sporadic, only ever somewhat capturing the spirit of the moment! Here I was trying out the Orgone module from Batchas, played with pitch/gate/velocity from Keystep - the gate also then clocks a DDSR to generate stepped voltages into a Penrose quantizer to tune the SynthVoice (proto x 2). A few x-mod'ing VCOs provide some modulation through the patch.
[sure that description makes total sense!]."
"It is an honour to be featured on the gemini horror show. 🙏🏼🤩🙏🏼 One of those you could play on loop all day. 😎✌️ And the visuals 🥰 I'm not sure if we have ever explained our products so well.
What you got here is the volca dream team. 😋 #ripcordusb 9v+ #usb powering all 3 volcas, using our 1 to 5 volca splitter cable. 🌟 Then you have our passive (unpowered) #mickXer in red, with coloured cables, giving a sweet and portable setup. 🎶⚡🌟⚡🎶 #Repost @gemini.horror
