Re: Aftertouch resolution?

 

Joachim: I read your TSB board website page with interest, thank you for the excellent explanation!

I have a customer synth here where a previous tech decided to replace all the 0.33 uF tantalum capacitors with electrolytics. It is my understanding that tantalums charge and discharge more quickly than their electrolytic counterparts.

Could you please elaborate on what you would expect to happen in the circuit with velocity timing when these tantalums get replaced with electrolytics?

Thank you!

Hi,
It's a ten levels analog signal. It is smoothed by a filter later in the signal path.
You'll find a detailed explanation of how it works here:

Great info!

Here's a snapshot of a spreadsheet I created and put under Files many years ago:

And here's how I did it:

Aftertouch resolution?

 

Hi all,
I've recently been watching a video about the internals of the CS80
and it briefly showed the aftertouch board. It looks like it has
multiple exposed vertical lines on the pcb, and then an inverted V
shaped piece of conductive rubber that connects more lines the harder
you press down on it.

Is this system essentially digital? How many different levels can it
achieve - what sort of "bit depth" is there?

Thanks
CS80 and CS60 for sale!

 

Hello,

I've got a CS80 and CS60 for sale here.? Both have Kenton MIDI and unison mods.? Both have been gone over by a professional musician and are working perfectly and in tune.? The CS80 has had all CMOS changed out as well as other upgrades.? Both have lids.??

Located in Chicago, IL USA

You can contact me at mike@... for more info.??

I would be interested in keeping a set as a backup.?

I’ll keep my eye on your progress and see how this project turns out.

Regards,
Nigel

I was wondering who is interested in new contact sets for Yamaha CS80. Together with a friend who has a high quality Markforged 3d printer I will produce a one to one copy.
As soon as it is finished and at least as good as the original I will place some pictures.
Please let me know if you also need new contacts for the yamaha cs80 because I can reduce the price by larger numbers
thanks
Re: Contacts for Yamaha CS80

 

Hi Tony,

I would likely be interested in a set of new contacts, please keep me informed on the development.

Thank you

Hi ! sir !?

hmm , you need the pedal that goes with it !?

Hi Scott,


Pardon the disappearance-act, life took over for a spell there. No audible difference when enabling the EXP WAH button, it seems like I have to do some reading online on how to properly diagnose the synth, and find someone locally to help.


Thanks again for all the input!

Re: CS-80: What's the normal stereo output balance between L-R channels?

 

How about if you push and latch the gray EXP WAH button on the left lower control panel, does it still do nothing?

I would say you found the part of the circuit with the issue. When you plug in the FC7 into the Foot Controller jack, it should automatically take over control of the overall volume.

Hi Scott,

I bought an FC7 pedal, but it doesn't seem to work with my CS-80 (or there's another issue somewhere), there's no discernible difference when pedaling.

I did try checking if the relative offset is the same when rotating the volume main, and the answer is yes. I guess this means the PRA-board is the issue?

Reboot Paris, I did check the service manual, but didn't find any mention of this issue. But perhaps the next step is to find someone locally to help me check and calibrate the values indicated in the manual. Or learn to do it myself (won't experiment on the CS-80 though, she's too valuable and fragile).
