Thanks Stephen.

Selling mint CS-80
Hello all,
I am preparing to sell my CS-80. I am the second owner, it was purchased by the original owner in March 1981 so is one of the last units. It has seen home studio use only. There is a bit of scuffing along the bottom, and a couple nicks in the bottom edges. But every surface that faces out or up is pretty much unblemished. It has all the original accessories, including legs, lid, music stand, leatherette bag for the legs, pedals, owners manual, original purchase receipt. I also have a clear plastic dust cover for it, so you can keep dust out but still see your prize in the studio even when covered. ALSO, I have a CS-50 in very nice condition I'll throw in as a long-term survival kit. Hopefully it'll be quite a few years before it needs to get cannibalized for anything. Also an extra KBC board I bought through eBay on a whim a little while back. I will be seeking top dollar to part with this. It is located in the midwestern USA. I can be contacted at dscr22@... if anyone is interested in learning more. |

CS80 Trim Pot/calibration help?
Hey gang,
A couple of quick questions for you regarding calibration: My CS80's main "personality quirk" pertains to the Initial and Aftertouch functions, and I'm wondering whether adjusting the trimpots for Aftertouch and Initial Level on the TRG boards might actually correct this. Bear in mind that both AT and IT seem to behave in the same way with regards to the bugginess. Simply put, when I play a percussive/Initial-reliant sound (i.e. E. Piano on CH I), some voices don't sound: -If I hold down a key, and cycle through the remaining voices on another key, Voice 8 is barely audible. -If I hold down two keys or more and cycle through the remaining voices, there are now two voices which don't sound--i.e. Voice 8 and a second (which I've yet to bother trying to identify.) My Aftertouch was reborn yesterday thanks to my genius albeit reluctant tech (you know who you are!) and to my mild disappointment it seems to not function under precisely the same conditions as the Initial. Engaging a single voice on its own, anywhere on the keyboard, the AT works beautifully. But if I'm holding down a note or a chord, the AT fails at predictable intervals. At first I optimistically supposed that the trimmers for specific voices on the TRG boards had simply got knocked out of whack somehow, but now I find it highly suspect that both the AT and IT could be completely out for the same Voices. Moreover, I find it strange that the AT/IT sounds properly on 7/8 voices when I'm holding down a single key, whereas an additional voice seems to fail when I hold down more than one key... Which to my very limited brain would imply I've got a bad CMOS chip or something on one of those pesky TSB/TKC boards... Much obliged for your thoughts and opinions--I basically just want to know if it's worth my while to fiddle with those trim pots or if I'm better off just 'playing around the problem' and leaving well enough alone. (As of this writing I am essentially tech-less so re-populating those boards is sadly no longer an option.) Cheers, Ted |

scam alert!!! - Re: Replacement KAS board? - Re: Voice allocation ?
Hey David,
you can log on to ebay, contact them about the item and paste the old item number. All they will do is remove the scam offer. They will not take any action against the person doing the fake sale, which is frustrating. There was another CS80 in the fall on ebay and all over the place on other lists which obviously was scam and I contacted them. They will always put the privacy rights of a fake seller over that of a buyer, unless a transaction happens within ebay. But the way these sellers work is that they will offer a potential buyer to buy it outside of ebay. After money has passed nothing will happen and ebay will not help the buyer. So it's better than nothing if you contact ebay and we can prevent an eager buyer from making a big mistake. Cheers Worsel --- In yamahacs80@..., "David Rogoff" <david@...> wrote:

Sources for replacement slide pots for CS80?
tim11g
I'm working on a CS80, and one of the slide pots is bad. Although 50mm
body length (30mm travel) pots are available in a few places, the 25mm shaft length is a problem. The longest I can find in a "standard" part is 20mm. Can anyone recommend any sources? |

sub oscillator external in / portamento question / detune slider
erikfromhere
Speaking about pedals, I like the way I can control vibrato-depth on
my Oberheims with a footpedal. I know, the CS80 has aftertouch to act as a source for vibrato-depth but I find it difficult to use this on chords. I was thinking, there is an external input for the sub oscillator. What if I take a sine-wave and use a cv-pedal to control the amplitude of that wave (using a modular synth's oscillator and vca) and feed it to the sub-osc ? Can I control vibrato-depth ? Does anybody know what the maximum voltage is that may be fed into this input ? Why did Yamaha implement this external source ? Did they have a foot- pedal available that provided a controllable sine-wave ? I never use any pedals with the CS80 but if it could control vibrato-depth I would use all the time ;-) And I have another question concerning the portamento: when I set the portamento-time to long I notice this has effect the ribbon too. When you slide your finger across the ribbon and let go, the pitch goes back to it's origin in portamento-style. Is this normal Concerning the detune slider. My CS80's are tuned extremely tight. When I set the slider at zero, there's allmost no beating between the channels (I like that). To set a usable detune, I have to adjust the slider just a little bit. I can't understand why Yamaha gave this slider this wide range. Well, all those questions. Still, the CS80 is my favorite synth. I discover new sounds all the time. I'm now into the 2 channels detuned sawwaves, the CS80 can compete with the Oberheims on these sounds. |

Anyway, it seems like a few people have worked on replacement KAS boards for the CS80. However, it doesn't appear than anyone has gotten one to the point of mass production / sales. I'm wondering if those of you working on them would like to get together to share ideas and maybe get a joint design working and ready to sell to the CS80 populous. I know there are issues of intellectual property and getting paid for design work, but I imagine, in the amazingly polite society of CS80 folk, this could be worked out. We could at least have fun brainstorming what features a KAS replacement board would bring: MIDI in/out Disable bad/out-of-tune voices Auto (or least least assisted) tuning Mono mode - with various key priority Unison mode (dynamic?) Different key assign modes Different glide/gliss curves A lot of stuff I can think of would also require replacing the TSB and TKC board. Basically, you end up replacing all the electronics under the keyboard, which would be great, and theoretically not too complex, but a lot of design work and rewiring! Dream away!
