Whilst I just scratched the surface, check out Marc Doty's no-stone-left-unturned run through of this fun synth for more: • The Yamaha CS-15
//
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 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 can 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 - There's two mixers. VCO 1, noise or an external signal can be mixed to run run through VCF 1. VCO 1 and VCO 2 can be mixed to 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 with time control and discrete for each oscillator), pitch bend and dual or single 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 very limited by comparison. 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.

It's just got that gritty post-punk quality that synths 10 years later (or before) just didn't have. I love it. I LOVE it!!

[@off711]

Funky jam at the end!

[@wingflanagan]

Being a software engineer as well as a (very) amateur composer, I have always supported digital instruments, recording, and sampling since they became available. Appeals to the tech nerd in me, I suppose. But there is something just ALIVE sounding about good old-fashioned analog. I mean, the world (and music itself) is analog, isn't it? Amazing little synth. Thanks, Alex!

[@AlexBallMusic]

Yep, it's an instrument in a very real sense. Very much alive.

[@lashtal]

The electricity is Surging through the electrical components themselves, and Moving. Analog instruments are literally Breathing, and I think that's what makes them sound so Alive. In the software world they talk about Machine Learning and AI... but I think the closest thing a machine can do to emulate Life is to Breathe and provoke/evoke an Emotional response/interactivity where- in a sense- the human player and the instrument become "one" in the symbiosis. I believe this is the true appeal of Analog Synthesizers.

[@err4071]

I agree with the other comments. i have also noticed that digital hardware effects and VST effects sound better on Analogue synth as well they seem to compliment each other especially reverbs and choruses and delays etc etc.

[@automaticgainsay]

I never watch demonstration videos of synths I've demonstrated because I am typically so frustrated by them. But yours is, of course, and as per usual, just absolutely wonderful. In such a short span of time, you have really hit on the major points of this incredible synth. But I'd expect nothing else. Perfect! Having two resonant band pass filters is really one of the most enormously wonderful things about this synth, and because so few people really engage in actual synthesis, the ability to employ formant synthesis to create vocal sounds is often missed. So many say "oh, this is some old monophonic analog synth... they're so limited." And yet, you can emulate the human voice with this one! I celebrated this aspect in a demonstration I did for a synthesis series I did for the Bob Moog Foundation that still, somehow, didn't make people realize that this synth makes an SH-101 or a Rogue, or so many others look like boring buzzers in comparison. Yes, I'll gladly defend that assertion. So, everyone... if you're interested in synthesis instead of having simple synthesizers that have status reputations, buy this... they're cheap, they're amazing, and they'll not only make you sound wonderful, but teach you how to engage in complex synthesis!

[@andyq9669]

And you might know someone who has done a series of in-depth explorations of this particular super-model.....

[@AlexBallMusic]

Thanks Marc, I'm glad it came across OK! It took you a full series of videos to _really_ explain what this synth is capable of and do it justice and so I was trying to find a way to draw people's attention to the fact that this synth is _so_ flexible but whilst making only half a dozen sounds for a 10 minute video. I almost felt rude to the CS-15 by stopping there. It's like it was saying "play with me more, you'll be surprised". I can't think of many synths in this category with two state variable filters with discrete modulation. That alone opens up a whole range of sounds, exactly as you say. Watching your BMF formant demo I think I basically did exactly the same thing you did, ha. I'll add some links and things in the video description because I feel a little dirty.

[@automaticgainsay]

I think it's just what happens with the great and unique functionality of this synth! Also, I think this was the first synth I ever played where you could adjust pulse width modulation independently on oscillators.

[@quantum.9883]

If you want to find a synth demo channel that's actually interesting, I'd recommend checking out Jexus.

[@MisAnnThorpe]

@@quantum.9883 Thanks but no thanks!

[@MelonadeM]

On the surface this looks like Just Another Synth From The Analog Era™, but hot damn. This seems to be closer to modular of the time with the way the oscillators, filters and amplifiers are set up. You even get CV inputs! What a beast of a synth this is inside, when it looks a bit unassuming on the outside. That sitar sound too, damn. Cheers for the great content, keep it up!

[@AlexBallMusic]

Exactly that. Like a not-modular, modular synth.

[@andyq9669]

The CS30 is even better, stacked with goodies and those super-smooth filters (not self-oscillating by the way). You can be processing drums and have them triggering basslines and adding other weird shizz at the same time

[@volt7cooltangs701]

We’ve all done it. Huge regret in hindsight. Sold my TR-909 & TR-808 about 1991 after I sampled them into my Roland Sampler and just used the samples which were great btw. Just found them too big at the time. Also have sold two Roland SH-2s, Oscar, Korg MonoPoly and a Jupiter 4. Doh! Good job I held onto 303, CR-78, 707, CR-8000, JP6 and Pro One. Thing is at the time they weren’t cherished or valuable.

[@PeteMOBie1]

Great demo Alex - I am fortunate to own one and love playing it. The CS-15 is criminally underrated and overlooked in favour of more famous American mono's. The tricks up this synth's sleeve are its modular-like versatility, control and the dual channel architecture that you demonstrated so well. It can be played as a pair of CS-5s layered, or as a 2 osc 2 filter beast or anything in between. The CS-15 can be played truly duophonically using a 2 channel MIDI2CV converter or a sequencer like a Korg's little SQ1. It has individual modulation depth controls like an ARP Odyssey, missing only envelope modulation of the pitch and PWM. The Glide can be used as an embryonic envelope to slur the pitch. The Dual Channel feature is something the Minimoog, Odyssey and Pro-One cannot do - layer a flute with a trumpet each with their own articulation. I've even had the SQ1 sequencer play the upper channel while playing the lower channel via the keyboard. Guitars/Voice can be processed through the external input. Loved hearing someone else get some great sounds. Yes you can put this through a Strymon Blue Sky and do Bladerunner on it! Awesome synth. I was heart broken when my white panel Odyssey died before Analogue restoration became fashionable again, but the CS-15 more than fills that gap. Keep 'em coming!

[@stacybigfoot4801]

Yeah, man. Great synth.

[@st0rmchild]

Awesome! I just bought a CS-10 a couple months ago. It’s a bit more basic than this but still has that classic Yamaha CS filter, envelopes so snappy they included 5x modes to slow them down to normal range, LFO that extends into audio rates, and springy keys that are really fun to play. Found the old guy at a second hand store for a really good price and thought I can always flip it if I don’t get on with it, but it turns out I like it a lot, and it’s staying.

[@andyq9669]

It is duophonic but only if via the cv/gate...you can sequence one path and play the other

[@volt7cooltangs701]

Roland SH-09 , SH-2 and the 1978 SH-1 have a better bottom bass end than the CS-5, 10 & CS-15 range. CS-15 can do bass but can create great sounds in the mid to high register and is very, very good at lead lines that really cut through. Very different sound compared to SHs, Pro Ones and Moogs. More Bandpassy filtery than Low Pass filtery. Basically I’m saying the low pass filter on this is pretty weak but the Band Pass and High Pass filters are good on this. One thing is that the build quality is bloody strong as is the keyboard quality. Sturdy buggers these. Even the single VCO CS5 was very good at lead lines that really would cut through when I used to gig it in the early 80s.

[@NAANsoft]

I bought a second-hand CS-5 back in 1988. And still have it. It sounds not bad for its size...

[@dillipphunbar7924]

amazing.instrument..gr8 jam

[@PeteSasqwax]

Just being able to trigger each VCO independently should be enough to secure its heavyweight status and there's a hell of a lot more to commend it as well! I had absolutely no idea this was even possible - it's the first time I've looked at my MS-20 and thought "why can't you do that?" (although I did immediately feel a little guilty for throwing shade at it)

[@eyeprod3101]

I have one. Would never part with it. It pairs very nicely with my Odysey. You can have the top row playing a sequence AND external input and still play the keyboard independently for the bottom row. My favorite feature though is the Brilliance slider. It can be like a crossfader between the two oscs and it can be amazing for "morphing" of tones.

[@AlexBallMusic]

Yes, that's one thing I thought about but didn't cover - a sequence and another line at the same time. I did the dual drum thing instead.

[@bennyshambles]

The “What Drum Machine?” sound is so great. Reminds me of the early Human League “drums,” although they most likely did that with their Roland System 100.

[@bniddo]

sounds very similar to being boiled

[@EspenKraft]

Great chaotic feel to the demo track at the end Alex! I have no personal experience with the 15 myself, only the 15D, but I really like the kind of dirty texture, or grit, that seems to penetrate every sound it makes. Seems like a lot of fun to use as a add-on (at least in my world of production) synth here and there to offset more polished sounds. Cheers!

[@AlexBallMusic]

Thanks Espen. Yes, it's a pretty flexible synth and translates to modern styles well, particularly if you want a bit of nastiness. After this video I still had it in the studio for a little while and it was interesting to compare to some original ARPs and the SE MidiMini clone I recently borrowed because those sound a lot "better", but the CS-15 has its own charms I think and it can do things those synths can't. It's still relatively cheap too.

[@MisAnnThorpe]

@@AlexBallMusic Yes, they WERE Alex, prior to 21/2/20.... thanks!

[@richardanderson8696]

I have a CS15. I find the exact opposite. I don't find it 'dirty' at all. It's a very clear sound, and the filter is smooth and tight rather than aggressive. It doesn't generate a load of nasty frequencies. It's clear and a touch understated. This makes it distinctive and depending what you want, it can be a real strength. It slots into a track far more easily. I have a Moog Subsequent 37 which in comparison to the CS15 sounds kind of overcooked.

[@kevinurso1944]

Alex! You’re damn good, man. Good riff up top, you should flesh that out.
