Yamaha CS80

... the description addendum says it is a diy modification, I provide the finished product, you install it, with or without soldering, ....it is available either way.The mod itself... It is pictured in the video.  The CS series keyboards are not easily moddable.... that is to say they don't provide jumpers, posts, extra connectors, or any real expansion minded spots on their designs. So it's not ever going to be an easy plug and play.... no matter what you do with the cs's, you have to make connections in some way, not just slap in a connector where there's a spot waiting for it.
That being said, I have made as easy as possible for those who don't solder to still do their own install. For the trulyunconfident they would hire a tech to install it, but it really isn't necessary

     I have formed a CAD designed board to accomplish offering a sync mod for the CS's... yes, all 3 of the 50,60 &80.It's listed on e-bay, but thanks to millions in recent medical bills and more surgeries for my wife, I can't pop the dough for the qty needed.  I am able to provide working protos, but that's not logical as it takes hrs tohard wire it all up. If any of you haven't seen this, here's the e-bay link:Yamaha CS80 CS-80 synth mod.

Hopefully, there's enough of you who appreciate the accessibility of this mod, cause until now, they cost a ton from Kent, plus you have to send your baby off to get it done. Hope you folks want some of these, I wiull only need about 10 days to stuff and ship the finished boards !  #yiv7373747311 #yiv7373747311 -- #yiv7373747311ygrp-mkp {border:1px solid
