Yamaha CS15

images via this auction.

"It's basically a 2 oscillator (VCO) synth with almost two of everything. It has 2 multimode filters (Low, Band and High Pass), 2 mixers, 2 VCA's and 2 Envelope Generators. It also has an LFO with three selectable waveforms and it goes from super-slow to super-fast. It actually reaches audio speed so you can do basic filter FM and get pseudo ring modulator type sounds.

There's also selectable Noise and External Input, so you can plug in your guitar, other synths, whatever and play it through the filters of the CS-15. I've put my guitar through it many times and get an excellent analog tone out of it. From nice clean filter sweeps through to classic 70's overdrive. Very nice!

The filter is 12db so it won't self-oscillate on it's own but I discovered that by plugging the Output into the Input, you effectively have a filter that self-oscillates for screaming effects and sub-bass. Don't worry, it doesn't hurt the synth!

It really is a thoroughly flexible synth with 38 knobs and 10 sliders for manipulation of your sounds. It does very convincing Moog type leads, basses etc but I had much fun doing experimental music with it. By doing the aforementioned output-to-input plug, and modulating the oscillators with the 'sample and hold' LFO and hooking it up to a cheap reverb, much weird fun was had!"

  1. CS15 in the driveway trying to sunbathe in private, but being stalked by Matrix who's packing some synth wood.

  2. I need a few parts for mine if anyone got a spare please let me know. It is a great sounding mono synth btw, I highly recomend one or two of them cause they are pretty light, keys usually have a nice feel along with higher note priority. A fun synth!

  3. Oh, these are beautiful and underated. CV in but non-standard format. The synth I cut my teeth on -- changed my life.
