Yamaha CS-01

Post by lhm1138 » Wed Apr 22, 2009 1:02 am

What's the story on these? I've heard they're analogs, I've heard they're DCOs with analog filters, I've heard they're "digital oscillators" with VCF/VCA, what's the straight dope? They seem pretty cheap, probably due to lack of CV and basic design.

They're OK. More of a novelty synth than a "bass monster," or "fat lead."

by pretty cheap do you mean they're selling cheap? i doubt that...
their strongest factors are simplicity and convenience. i use mine more in making up a melody before programming it into a sequencer than any other keyboard.

the filters aren't the greatest and the glissando breaking out steps sucks, but they do have a nice, simple sound.

I think it is a VCO actually...not a DCO. They are cool synths. Not the most versatile, but still cool for messing around with.

From what I remember, the CS-01 architecture is different to every other CS. It uses an all-in-one keyboard decoder and osc IC, there's glissando but no portamento, and the filter resonance on the MkI is switched lo/hi, not constantly variable. It's very, very basic, and if you're a) not short on space, or b) don't need something battery-powered and portable, I'd recommend a CS-5 instead. I had one for 10 years, and the only thing I thought it did particuarly well was a mean PWM bass. Kenton used to make a CV/gate kit, but it cost more than the synth and is now out of production I think - I contacted them about it shortly before selling my 01 for six times what I'd paid for it...

I have a CS01 mk1 and I think it's a cool synth.
It sounds different from the other bros of the CS family.
It sounds more "minimal", it has a less harmonic timbre, more 80's than the CS-5, it can sound retro but also really modern/futuristic.
The only think I dislike is that has low volume (I think because it's a battery powered synth) and , some "control/logic" noise flows in the audio path.
The noise it's really low but if you pay attenction you can hear it, the clock of the lfo or pwm rate, however nothing to be scared of...

I love my cs01. wish i hadn't sold the white one i had to smallsynth, but did i really need 2? i think it sounds good midrange. bass is really low audibly on mine, and the high stuff gets kinda dirty. maybe i just need to clean it.
anyway, the manual says its a vco. then again, so does the synth.

Ok. Here is what you need to know about the CS 01:

1.It is a VCO analog synthesizer

2. It is small and simple and battery powered

3. It has the best 1 osc pulse width modulation sound you have ever heard. My bandmate and I easily agree on this.

4.It is not a toy. It is underestimated.

Can anyone confirm if it's actually a VCO. Peter Forrest in his A to Z of Analogues speculated that something digital was going on (because it had glissando rather than a proper portamento I think), and I think I remember (not 100% sure about this) that the synjack project for the CS01 fell apart because it was actually a digital Osc.

All I know is that the CS01's tuning is rock solid from switching on, and it's a nice sounding Osc whatever it's nature. I'd be really interested in hearing if anyone has anything definite on this. As far as it saying VCO on the synth, doesn't the An1x label it's Osc's as VCOs!

I've had one or two in the past and they sound more like VCOs to me. I'd be shocked if they were DCOs.

My CS01 has portamento increasing in time until you push the slider past halfway when it becomes glissando increasing in time beyond that.

All the CS-5/10/15/30 synths have really stable tuning that's in tune pretty much from "go"... I too would be surprised if it was a DCO.
Do you even post on vse bro?

I think you'll find that's just glissando that's quick enough to sound more or less like portamento.

As far as I know it's all analogue. Sometimes I wish I'd kept mine, though I'd have preferred a mk II with the full resonance slider rather than the mk I's hi/lo switch. It's a fun synth, especially with the BC-1 breath controller (I kept that & now it gets used (occasionally) with the DX11).
