CS-15D Demonstration Part Two.

I know these are old videos but I love them so much. I literally bought a technics sy1010 because of your review. Personally, your vintage analog synth videos are my favorite but I'm glad to see you're still making videos man. Please never stop!

[@automaticgainsay]

Hey, thanks a lot, Jay!

[@mootbooxle]

You were very enthusiastic about this synth! It made me smile a lot. :)

[@automaticgainsay]

+mootbooxle I'm glad it made you smile! This is a terribly underrated synthesizer! :D

[@infindebula]

Marc you probably already figured this out, but the LFO "Repeat" setting does its re triggering job without random s/h effects when the mod wheel is all the way down. Turn up the mod wheel and it adds random effects. This works real nice with percussive or synth bass sounds, and a small amount of VCF mod. In fact, if you turn the LFO rate all the way down and leave it on "repeat", you can get small random filter changes on each note you play, but you won't get repeats unless you hold the note down for an unusually long time.

[@infindebula]

@InsertName125 It's Yamaha's unique 2-pole filter. It is very musical, and rather bright.

I have had a Yamaha cs15d for a while now, and I always get great sounds from it. When i pair up cosmic 2 on the top channel. to manual on channel 2, after adjusting, I get what sounds like some Roland jupiter 4 bass. wow.

[@Synthelicious]

You're right, it's a pretty cool synth!

[@nickpritchard7130]

Great Vid Marc..Thanks.

[@InsertName125]

I know it sounds strange, but to my ears, the Yamaha CS synths all have a distinctive noise sound. I'm probably imagining that, but the noise on these actually sounds unique to me.

a synth like this don't play the red led when is connectin to the wire it doesn't work U got some help info? tnkx

[@jsaulkane5893]

its a great keyboard.. mine is all over my tracks in the 90s

[@hongdekong]

your such an awesome dude im glad i subscribed your channel

[@JordieMack7]

I am planning to buy one of these bad boys on ebay from japan, and I live in australia, can i get all the cables in australia to run this synth? thanks :)

[@craigpenton6167]

been thinking of selling mine, in Australia all ready to go

[@justinandrews929]

Hi there, just wondering if you can confirm something for me - is it possible to control channel 1 of this synth externally, but then play channel 2 with the keys?? Thanks, great vid!

[@automaticgainsay]

I think you can only generate channel independence through external control, alas.

hey, is there a full version of the song from your intro?

[@Marzanphoto]

How much would be fair to pay for one of these in 2023?

[@automaticgainsay]

They are still bizarrely comparatively cheap. I would take one of these over a Roland SH-101 or even a Moog Prodigy, and yet, they sell for easily half.

Why the dreadful quality?

It's not "two synthesizers", it's a "two oscillators, one synthesizer" synthesizer...

[@automaticgainsay]

Tell me more about synthesizers

[@oriomenoni7651]

@@automaticgainsay It's one synthesizer under all respects. To start with, it's one box with one keyboard; secondly, you can't play the two oscillators separately unless you drive it externally with a second synthesizer via cv/gate, and even in this extreme, rather rethorical case, you still need two synthesizers to play the two oscillators separately. Thirdly, many of the controls are common to both oscillators, which even logically goes against the weird concept if it being two synthesizers... Finally, nobody considers (for example) Roland's D-550, as two synthesizers... nor Yamaha's DX7 Mark II for that matter, nor any other bitimbral or multitimbral synths... even in those sinthesizers, playing two different timbres by split or stack is considered a quality of them still being one synthesizer, not two... let alone the dear old CS15D where youcan't play two keys at once....let's stick to some common sense, for gawd's sake. Anyway, I really appreciated your videos, very thorough, and very useful for potential buyers of this little big synth. So thanks for that.

[@automaticgainsay]

@@oriomenoni7651 You know, if I ever make more than this one synthesizer video, I'm going to consult with you... you plainly know a lot about synthesizers

Seriously, the point is… and this is a very important point about a unique aspect of this synthesizer… it has all of the components in two signal paths to complete two entire voices. It has the equivalent of two individual single-osc monosynths within it. The point I am making is that it is sad that the keyboard wasn’t designed to implement a duophonic outcome. The only thing that is missing is a relatively simple keyboard voltage function… if it had this, this synth could play two unique individually-articulated voices independently. This architecture is rare in the realm of vintage synths, and it’s odd that it wasn’t capitalized upon.
