From: Heath Finnie To: yamahacs80@... Sent: Tuesday, April 07, 2009 1:29 AM Subject: [yamahacs80] quieter keys One last issue. On mine keys 20-25 (G-C) are playing at a quieter volume, but only on certain presets (but both channels). Clav and organ are the most noticeable. I just cleaned all the sensors, but it shouldn't even be related to those since those are mainly for aftertouch. |

Re: RIP Toby
Hi Rob,
Sorry to hear of your loss. I know how your feeling. I too lost my Misty and Moog last November ten days apart. best regards Kent _________________________________________________________________ Free photo editing software from Windows Live?.

Re: Free CS-80 album - Bartesho

This is an album called `Bartesho'. I'm currently offering it for free here on my site for a limited time. It was improvised using nothing but a Yamaha CS-80 synthesizer and some reverb to add some "space" to the recording. I hope you enjoy it. The mp3's are encoded at 360kbs for better quality. It's fairly ambient but does have more experimental sections as well.Excellent stuff - thanks! |

About the aftertouch problem , It will may sound easy. but have you checked the 8.5v rail supply on the keyboard ? It may have broken from lifting up and down the keyboard --- yamahacs80@..., "Heath Finnie" <heathfinnie@...> wrote:

Re: Raising circuit board rack for tuning
honestly, i MUCH prefer just leaving the entire assembly down and tuning that way. i also seem to get a bit more accuracy with it down. using a static wristguard and a plastic tuning piece, i just gently push the wiring above up a little. works fine for me. good luck.

Re: Raising circuit board rack for tuning
Hmmm.. could be done - but I'd prefer to make it pneumatic David..!

Re: Raising circuit board rack for tuning
No springs Kent, just make sure you pull it up level, that is at the same rate both ends. It is kinda heavy I suppose (because you're leaning over to do it) but I'm used to it. The cables (looms) are designed to 'give' as it rises so there shouldn't be a problem if you go slowly.

Just opened up the case and started looking around.You might need to undo a couple of the heavy wires they use to hold the big cable bundles in place. HOWEVER.................. As I finally realized after tuning CS80s for many years, if you're just doing the usual tuning procedure, you don't have to, and shouldn't raise the card frame! All the trimmers are accessible with it down. You just need a flashlight and to push the cable bundles up and out of the way. Leaving the cards down should make the temperature change less, so the tuning should hold better when you close up the lid. David |

I'm sure I'm gonna have to carefully make sure no cables get caught up on anything. Cheers, Kent On Apr 5, 2009, at 12:10 PM, Quazimodo wrote:

Two bolts will need to be undone (one either side) and then the whole rack just slides up and locks by itself. To lower, you just raise it slightly (so it un-locks) and then gently lower it back down. Cheers TOM --- In yamahacs80@..., omegacode80 <omegacode80@...> wrote:

Re: no pitch change . microsine nightmare

Ho, yes for the records! Sorry !

Well the problem cannot be applied to a normal cs-80 . but here was the problem . A jumper was removed between ground and ic14 to ic20 ground rail , so all K output were floting . Probably removed by the devil or simply to make the microsine system work ,,, Good thing i have keen eyes because I am new to this polyphonic system and i could have been searching the problem till the end of time,,. since... all parts were testing ok . Now the pitch is changing but i got many other problems , i think i got some wiring wrong on the preset matrix , it work but in a very wierd way . also the keyboard controls is giving me problems . Is the center tap position really to ground ? and a complete calibration needs to be done. One output is dead . etc etc ,,,,, It sure make strange music ,,, all vco are giving different octave , out of this world music ,, ahahah As i am here , i need some more parts .. All the knobs ( rotary )tune speed depth volume etc. The mix fader it is a dual gang , balance ( was replaced by a normal fader , microsine again ) 4 ig00157 ( they are on the tone selector assembly pcb ) or if someone know with what i could replace them , it is probably a simple transistor array . sting 3 string 4 panel 1 panel 2 harpsicord 2 , pushknobs . after that it will be complete .... And one more CS-80 on the road .. . . next time ! i will start the hunt for wrong wirering .... . --- In yamahacs80@..., "Heath Finnie" <heathfinnie@...> wrote:
