What I meant Mike, was that should an Osc chip 'blow'... you'd more than likely not find another '11' anywhere. If you did find and Osc chip to replace it with you'd just have to use whatever came your way!

I'm having trouble understanding what you mean.. I bought it because it sounded awesome even though I already have a CS80. After taking it apart and going through the calibration routines, I noticed that all of the Oscillators are factory coded 11.

This is the way that I bought it. I didn't modify it or swap cards. I picked it and chose it because it was the most in tune CS60 I've ever heard.

I've got a Yamaha CS-60 for sale in Chicago, IL. It is from my personal collection. Everything works fine and I have replaced some sliders that were a little bit dirty. It is an exceptionally stable CS60 because all of the oscillator chips are factory selected "11."

In the factory, Yamaha paired up all of the oscillator chips with similar temperature response characteristics. If the heat went up, Yamaha wanted the scaling to go up the same amount with all of the oscillators.

According to Yamaha literature, "Each IC built into the "M" circuit board is ranked and labeled every 5 Degree C according to the degree of change in the musical interval on C1 and C6 affected by the ambient temperature change from 25 to 50 degrees C."

A value of 11 is the best and 96 is the worst.

Anyone ?

Hello to all

My CS 80 Sub Oscillator works fine with aftertouch but not direct.
And one of the preset selector lamps stopped working (bass) what
kind of replacement should i look for ?

The other problem i have: my CS 60 is just the opposite the Sub Oscillator works fine direct but not with aftertouch.

any clues on these matters ?

Thanks in Advance

Is there maybe somebody over here who has the complete and correct dimensions for the CS 80 stand ?

I realize that this is a CS-80 forum, but does anyone know the name of the type of power cable on the back of this Yamaha DX-1 that I own? Please see the attached picture. If so, does anyone know where I could buy a cable/connector that would work for it?

Thank you,

Mitchell

Hi Constantin.

Welcome to the group. Sounds like it's probably a simple problem. If you look at the giant, overall schematic ( ), you'll see in the upper left corner that the keyboard is scanned as a matrix, like a computer keyboard, from the KAS chip. The low octave (not counting the lowest C, which has its own special pin) all have the U1 signal in common from the KAS chip / board. If you look at the KAS circuit board layout ( ), on the right edge of the board, about a dozen pins from the top, is this signal, U1. According to the invaluable wiring labels, this is a red shielded wire that connects to C1 - the lowest key. You can see the wires on the circuit board at the back of the keys that holds the metal key contacts. You'll see that each circuit board hold 6 keys except C1, which is all by itself. Since that key works and the next octave doesn't, it looks like the jumped wire that connects U1 from that little C1 board over to the board next to it is broken.

If you're somewhat familiar with electronics and know how to open up the lid, this should be pretty easy to check. If not, find someone who is!

Good luck,

David

Hi there,

My CS80 was working fine until today, when I noticed the lower octave stopped triggering any sound. All other keys, ribbon and knobs work great.

More specifically, the lowest C key on the left of the keyboard works but every key after D, E, F, G, A, B, C (and the respective black keys) does not trigger any sound. The second octave (after C) and all other keys work just fine.

If anyone has experienced something similar and was able to fix it, would love to hear back. Also any advice is greatly appreciated. Thank you for your time,

Constantin

Betreff: [yamahacs80] Re: any other MIDI retrofit kit ?

My mistake, my first Cs80 was serial number 1014, bought from Peter
Forrest
at the turn of the century of thereabouts.
My current CS80 which ive had since about 2003 has a serial number around
1200 i think.
I always thought there were about 2000 made, but perhaps only 800-1000
after
all. I wonder how many are still working and how many got broken up for
parts or scrapped? Maybe 500ish still survive?
I bet Vangelis still has a few hahaa ;)
Ill never part with mine

My first Cs80 was serial number 900 something.

AFAIK from my times being Yamaha Product Specialist, older Yamaha
products for public market start serial numbering from 1000 up. If

there

are some machines with numbers under 1000, they are prototypes or
testing pieces.

Maybe that's the reason for a mistake.

Newer products use different coding system, not just simple numbering.

1000 made you say ? So synthmuseum is wrong claiming they were 2000

I'm pretty sure. I've never seen/heard of a serial number under 1000
or over 2000.

There's a guy in the Netherlands called Mark Cox who makes a MIDI kit for
the CS 60, I don't know if he also made something for the CS 80. His
website - only useful for contact info - is: *cox*-*electronics*.com . The
CS 60 kit is quite a bit cheaper than the Kenton kit at about EUR 400
*including* fitting it, instead of the EUR 755 for the Kenton kit including
fitting!

Hi, I would like to know if there is currently any alternative to the Kenton retrofit kit to control a CS-80 via MIDI ?
Thank you for your informed replies.

Not that I've ever seen. There were only about 1000 CS80 made. I'd guess there's about half of them left alive and maybe 200 people who'd want and pay for a MIDI mod. I'd also guess that at least half of that last group already has had a Kenton installed so there's not a big market for an extremely complicated interface.

I just wish Kenton would add MIDI out to their kit!
