Re: Clean CS-80 Overall Circuit Diagram

 

Hi Tom,

Thanks for pointing these issues.

You're right concerning the 100uF capacitors. There are 4 decoupling capacitors; two between ground and +15V, and two between ground and -15V. I changed the 33uF one near the IC1 to a 100uF, and I added a new 100uF one near the IC3 (which corresponds roughly to where it really lies on the board).

As for the 4.7uF capacitors, those on my boards are in compliance with the schematics. Two are polarized and are yet other decoupling capacitors (between -15V and +15V, this time). The other two are non polarized and are located near IC8 and IC9.

I updated the overall circuit diagram to reflect these. It is available .

I also put in the photo gallery of the CS80 group a copy of the M-board schematic (p44 of the service manual) where I highlighted the 42 capacitors, and also fixed a couple of missing components and a label inversion (fixed in red). You can find it .

Re: Clean CS-80 Overall Circuit Diagram

 

Hi folks,

Currently I am looking at the 'M' boards in one of my CS80's with view to recapping and?I had a look at the circuit diagram to cross ref against what I see on the board.

On the board I see 4x 100uF capacitors... yet the schematic only shows 2 (near the IG00153).
I cannot find the single 33uF cap on the board which is shown near the VCA/IC1 on the schematic.
I am assuming that they fitted a 100uF there - which still leaves one of the 100uF caps unaccounted for..!

I also see 4x 4.7uF polarised caps on the board... yet the schematic shows only 2 (across the power rails next to each IG00156)

There also seems to be 4.7uF anomaly though... the polarised ones are 50v rated whereas the non-polarised ones are 16v rated on the schematic. Also on the schematic, non-polarised 4.7uF are marked 'NP' but the one near the IG00153 shows as 16v but doesn't make any reference to polarisation..!

So the question is which are these other 4.7uF polarised caps...?

I think the schematic needs updating here as well..!?

Cheers,
Tom
Re: Tomita Memorial Museum display

 

The CS80 was also used on the 1984 "Dawn Chorus" album (also
known as "Canon of the three Stars"), in one of the renditions of
the Villa-Lobos pieces (some brass patch). Thanks for the
heads-up, nice to see some of Tomita's gear (although I'd rather
see him use this stuff for another great album).

Thanks, I was discounting that one because while it still sounds like Tomita, it's generally quite digital sounding.

I've always felt his 1992 "Storm from the East" OST was his most Vangelis-like performance though I've not listened to specifically ID CS80 or lack of it and it surely contains samples.



His Bach Fantasy (1996) was an intentional back to analog sounds album and his last mostly new classical realizations album though he told me he was sampling his own modular to create polyphony by then. It contains some (not yet released virtual analog) JP-8000 too



His last major work, a ballet featuring Hatsune Miku called "Dr. Coppelius" is being premiered on stage this week in Tokyo. It's inspired the 19th century Hoffmann tale about an inventor who builds a clockwork girl that inspired ballets by Delibes and Offenbach - though Tomita was composing rather than interpreting their works. As with most of his own composed work from the last few decades, it's a blend of synths and live orchestra and can be staged live.

Quite a few interesting classical fragments have been released officially in the last decade or so, like an unfinished but amazing opening of Rimsky's Schereazade (late 1970s?), Debussy's Nuage completed in the mid 1970s., a longer Tristan & Isolde, a half hour of partly finished pieces all from (Disney's) Fantasia with a fun and finished sounding Sorcerer's Apprentice and fragments of Nutcracker Suite with samples and vocoder singing. What sounds like a physically modeled Debussy's Arabesque 1 came out not long ago.

Betreff:?[yamahacs80] Tomita Memorial Museum display

There was an exhibition called Synth Fest 16 in Tokyo last weekend. A major highlight was a selection of Tomita's gear. Tomita's long time associate Hideki Matsutake (Logic System) was either willed or made executor of Tomita's synth collection and this is the first big public display since his death in May.



(Ishibashi is a music instrument retail chain reporting on the show as an event, I just used their link since I know people don't always want to deal with facebook)

Notice Tomita's CS80 has a CV and Gate ("T" for Trig?) mod for each voice. I also see he signed some of his instruments presumably to prove they were his in the future.

Tomita's main use of the CS80 was on the album "Daphnis et Chloe" (called "Bolero" in the US and "The Ravel Album" in parts of Europe) he also used it on "Grand Canyon" though not as obviously. I've not heard mention of his using the CS-80 as a controller for presumably his modulars. He definitely was always into looking into techniques in speeding up his painstaking multitracking process.

One of the more unusual items is what looks like a small trade show display of high quality synthesizer pots that I guess at some point Tomita was involved in the re-manufacture of. The other, more of digital fans is the Casio Cosmo prototype system. My understanding is Casio wanted to do a high end sampler and Tomita was hired as a consultant and endorser. They eventually did put out the prosumer level FZ-1 but by then other companies had carved up the sampler market.

Re: Some CS50 and CS80 demos uploaded

 

Hi Florian,
?
for the CS50 track I only used the Roland 330 combo (SRV/SDE/SDX) so I guess the little bit of?chorus you're hearing is the Dimension D simulation the SDX-330 produces.

Fine tracks! Thanks for sharing.

Wich effects did you use on the CS-50 track? Is there a chorus on it or
is it "only" the reverb?

Wow! Incredible background info, Stephen. I noticed that the Chorus ?and Leslie switches have been moved up in line with the pitch ribbon.

YAMAHA CS-80 for sale

 

Hello my friends,

I have made the decision to eventually part from my beloved monster synth YAMAHA CS-80 that I purchase 2001. Over extended period of time I completely restored all capacitors, OPAMPS 4000 CMOS, trimpots, and even upgradeded tuning pots all to multi turn bourns pots. The Synth is very stable in tuning and over all. Never had an issue. Al tuned to factory specs.
I am selling it because I have a family now and would have to liquidate most of my vintage gear.
It comes with a huge and custom made flight case. And has it’s own very sturdy legs. (Not original Yamaha!)
I am asking 20’500� and can provide photos for serious buyers. The synth is located in Basel, Switzerland and could be shipped Worldwide.

Re: CS-60 Sustain issue

 

Hi,

Thank you both for your detailed answers. The brilliance controls do affect how much of what I called an “oddity” is present (in the center position, it seems to go away), so both of your descriptions make perfect sense with what I am hearing. Great to know that nothing is wrong with my CS.

best,

DT
Re: CS-60 Sustain issue

you are experiencing some of the features of the cs60s 80s... in sus 1 the releasing portions are controllable by the scaling.... if you have the Low portion of the keyboard with less vca and a brighter filter, those attributes will be added to the releasing stage....? things not able to be modulated upon release in sus 1 are pitch (ribbon)...? if you play a chord in the middle and let it release and play the high zone with a VCA boost and a VCF cut, that will affect the middle hanging notes the same way....

I use my CS80 like this rhythmically to create a manual type of sequence playing... playing rythmically in and out of lower and upper regions

Hi,


I'm not certain that the sustain functions are working correctly on my CS-60. It seems as if the notes in Sustain I are being cut off when they are not supposed to be.


Here is one environment where I can hear something odd:


1) I close down the low pass filter and set a long release on the panel (2-3 seconds at least)


2) I then play a chord and then hit a short note on the lowest C (picked only because it will make the oddity more noticeable).?


3) I would expect that hitting this lowest C would NOT kill the chord as it is is releasing, since in Sustain I all releases are independent. BUT it DOES kill off the entire chord.


4) Next issue is that if I quickly hit a middle C key while listening to the final moments of the release from the low C (which killed off the other chord), this causes the first hit low C note to suddenly get louder AND the chord that was previously cut off returns (provided the release is still within its originally set time frame/trajectory), and it even sounds like its filter is opening again.


Is this weird behavior, or is this how Sustain I should work?


I should note that the ribbon is currently removed for repair, in case that somehow affects release times (not sure why it would though).


Thanks?DT
Re: CS-60 Sustain issue

Hi DT.

I think I know the effect you are talking about and it’s normal - if not what you’d want. ?The problem is that that there are 3 DACs that each output the voltages corresponding to the notes played. ?The main one is on the KAS board and each of the 8 voltages go through sample/hold circuits on the KAS and S/H boards. ?This is where the Sustain I/II logic comes in and freezes (or not) and note voltages. ? However, the KBC boards also have DACs which are used for the Keyboard Control Brilliance/Level High/Low. ? These don’t have the sample/hold circuits or “know” about the Sustain mode. So, you play a high note with a long sustain in Sustain I (or is it II - I forget) and then hit a low key. ?The high note is still sounding but its filter/volume could suddenly change if the Keyboard Control knobs aren’t at their center positions since the keyboard scanner will tell the DACs that all 8 notes are that low note.

Hope that makes some sense.
