CS60 aftertouch question

CS60 aftertouch question

2008-09-18 by Alessandro

i bought a near mint CS60 yesterday, looks nice with my CS80.

But the CS60 has a few (minor problems) the aftertouch for instance is 
always on. Any touch response settings are directly audible, when i 
press the aftertouch nothing happens. I know that the aftertouch works 
with a light bulb. I opened it up the light bulb still works, if i put 
a piece of paper between the light and i think the sensor then the 
touch reponse stops. So somewhere there is a fault perhaps the sensor? 

Does somebody have any experience with this problem, can i fix it 
myself or do i have to bring to a (experienced) technician.

Thanks in advance,

Alessandro

Well, there should be some kind of shutter between the light bulb and 
the sensor that lets more light through as you press harder on the keys. 
Look around area A-4 in the schematic here: 
http://therogoffs.com/cs80/manuals/CS60_Service_Manual/cs60_foldout_schematic.jpg 
.  You should set some kind of lever move near the light bulb when you 
press the keys hard. Maybe the attached shutter fell off. I don't 
remember what it looks like - it's been over 20 years since I've 
owned/worked-on a CS60, but it should be pretty straight forward to fix.

Hi David,

thanks for your help.

Now you mentioned it, i think the shutter is missing (its not in the 
CS) but i think i can make something else for it. Nice job i will do 
tomorrow ;-)  its bedtime here..

Thanks,

Alessandro

Tuning

2008-09-19 by Scott Metzger

Hey David.


So my CS80 is out of tune again.  It isn't dramaticly off, but it is off a good +12, or +25 cents on some voices.

Do you know why this is happening?  How do we get stable tunning so I don't have to open this thing up every week?  Also, where on the card do I jiggle to see which Voice I am on?

Thanks

-Scott


Also, to find Voice 8, I need to hold a note down, then press A untill I find Voice 8 correct?


Also, what is the first POT on the voice cards?  I think I might have turned those first pots by mistake.  

:(

oops, after closer inspection i found the lever in a corner inside 
the CS ;) I'm going to clean it and glue it back on :)

thanks you all!

figure i'd save david a little breath....

-voice 8-correct. 1 note sustained +7 notes triggered=voice 8

-trim pots, from top:
-little blue one-scale
-2
-4
-8
-16
YOU MUST DO THIS FROM THE TOP DOWN!!! 2' offsets all other octaves. ( have forgotten this several times!)

STABILITY: maybe want to redo the thermal grease on the VCO chips? other than that, i would guess you might not be getting consistent voltage supplied to the cards, unless it is the same voice always falling out of tune. good luck.

RE: [yamahacs80] Tuning

2008-09-19 by rj krohn

here's how i do it:

-select OSC 1 only.
-tune voices 1-8 at A1.
-scale voices 1-8 at A4.
-check tuning of voices 1-8 at A1, if needed, repeat step 2.
-then tune voices 1-8 at 4,8,16. doesnt matter if you do by voice first or octave, really. i find it easier to do each octave at a time, YMMV.
-select OSC 1 and 2, and follow same procedures but tune to beats, not to tuner.(THIS ONLY WORKS THOROUGHLY IF YOU KNOW THAT ALL VOICES OF OSC 1 ARE VERY CLOSE TO A "TRUE" TUNING. IF YOU TUNED OSC 1 VOICES TO EACH OTHER AND NOT TO A TUNER, YOU HAVE THE POTENTIAL TO END UP OFF DUE TO DRIFT). 

good luck. also, i actually find it easier to do voices 1-7, and then go back and do 8 by itself each time, cause i can keep track of the voices without turning on and off. again, YMMV.

RE: [yamahacs80] Tuning

2008-09-19 by rj krohn

the little blue top pot, above the 4 BIG tuning pots, scales the voice, so that A1 and A4 should still be (close) to 440. if your scaling is off, you can play in the bottom 2 octaves of the kybd and be in tune, while higher octaves get progressively worse.

you might need to go back and forth between 2' tuning and scaling a few times, as the scaling pot offsets the voltage. this is where the katsura tuner plugin really shines to me, as it can be very hard to tell otherwise(by ear, gtr tuner) how you are doing at A4 on 2'(its dog pitch high, to my ears!)

RE: [yamahacs80] Tuning

2008-09-19 by Laurie Curry

Okay....

This is completely backward with my tuning proceedure....

1 make sure detuneII is centred and the dual pitch tuning is
centred....

mix 1 for 1-8, mix 2 for 9-16...

open her up....

As I know it.....the little blue ten turn pot....is the "pitch" of the
2 foot osc...

adjust holding A1 with a plastic screwdriver....clockwise flattens,
counter clockwise sharpens.....

.....the next larger trimpot is the Octave scaling Calibration
(guitarist would call this intonation) between lower and upper (set
using 2 foot on A5)...Turn clockwise to compress the range-(A1
sharpens as A5 flattens) or counter clockwise to expand the range (A1
flattens as A5 Sharpens)...then re adjust little blue on
A1...repeating until all 2 foot oscillators are bang on at both A1
and A5....

from this point it gets much easier  as the trimpots aren't so touchy
.....the next trimpot is the 4 foot tune offset......counter clockwise
sharpens....setfor all then

.....the next trimpot is the 8 foot tune offset....counter clockwise
sharpens....set for all then

almost done champ

.....the next trimpot is the 16 foot tune offset.......counter
clockwise sharpens.....you will find the trimpots are much easier in
this range....

Close her all up and play with the mix in the middle....listening for
beating......repeat procedure if neccessary...

ok, just consulted the manual. we're both a little off, but you are closer to right"

top blue pot(VR3) is 2' pitch, 1st big pot (VR2) is offset, HOWEVER, it also says to tune 2' pitch at A4, and offset at A1. i have been doing this backwards, and have somehow come up with tuning that is spot on, or within a few cents across the keyboard. wierd....

Okay....



This is completely backward with my tuning proceedure.. ..



1 make sure detuneII is centred and the dual pitch tuning is

centred....



mix 1 for 1-8, mix 2 for 9-16...



open her up....



As I know it.....the little blue ten turn pot....is the "pitch" of the

2 foot osc...



adjust holding A1 with a plastic screwdriver. ...clockwise flattens,

counter clockwise sharpens.... .



......the next larger trimpot is the Octave scaling Calibration

(guitarist would call this intonation) between lower and upper (set

using 2 foot on A5)...Turn clockwise to compress the range-(A1

sharpens as A5 flattens) or counter clockwise to expand the range (A1

flattens as A5 Sharpens)... then re adjust little blue on

A1...repeating until all 2 foot oscillators are bang on at both A1

and A5....



from this point it gets much easier  as the trimpots aren't so touchy

......the next trimpot is the 4 foot tune offset...... counter clockwise

sharpens.... setfor all then



......the next trimpot is the 8 foot tune offset....counter clockwise

sharpens.... set for all then



almost done champ



......the next trimpot is the 16 foot tune offset...... .counter

clockwise sharpens.... .you will find the trimpots are much easier in

this range....



Close her all up and play with the mix in the middle....listening for

beating..... .repeat procedure if neccessary.. .

Thanks RJ.So when I first tune step 2, do I tune it across the board

for all voices first, or do I just start on one voice and tune from 2

to 16?-ScottTo: yamahacs80@yahoogro ups.comFrom:

Re: [yamahacs80] Tuning



figure i'd save david a little breath....



-voice 8-correct. 1 note sustained +7 notes triggered=voice 8



-trim pots, from top:

-little blue one-scale

-2

-4

-8

-16

YOU MUST DO THIS FROM THE TOP DOWN!!! 2' offsets all other octaves. (

have forgotten this several times!)



STABILITY: maybe want to redo the thermal grease on the VCO chips?

other than that, i would guess you might not be getting consistent

voltage supplied to the cards, unless it is the same voice always

falling out of tune. good luck.

Hey David.



So my CS80 is out of tune again. It isn't dramaticly off, but it is

off a good +12, or +25 centson some voices.



Do you know why this is happening? How do we get stable tunning so I

don't have to open this thing up every week? Also, where on the card

do I jiggle to see which Voice I am on?



Thanks



-Scott



Also, to find Voice 8, I need to hold a note down, then press A untill

I find Voice 8 correct?



Also, what is the first POT on the voice cards? I think I might have

turned those first pots by mistake. 



:(

It works both ways, but it is a much faster proceedure to start with
the low to rough the tuning into the ballpark and then see how far out
A5 is....if you are a notch flat, at A5, sharpen it to "half a notch"
by expanding the scale(counter clockwise)....when you return to the
low A it will also be half a notch flat......turn "little blue"
counter clockwise to "440" and you should be close to finished with
that one.......when I do it the other way, it takes me twice as
long.....same results....

ok, just consulted the manual. we're both a little off, but you are
closer to right"

top blue pot(VR3) is 2' pitch, 1st big pot (VR2) is offset, HOWEVER,
it also says to tune 2' pitch at A4, and offset at A1. i have been
doing this backwards,and have somehow come up with tuning that is spot
on, or within a few cents across the keyboard. wierd....
