Subject: KORG POLY 6 fixed with klm-367a caveat

From: nmr2@rocketmail.com

hi all

 I'm glad  that my poly six is working great after installing the clone pcb klm 367a.

Although all the analog stuff is fine, I do notice that some digital line "noise" affects the programmer section from time to tine where multiple buttons light up and i have to sort of reset the machine by pressing A button and number 1 button to get back to that patch.  somethines not even that works 


i thought i saw some fix with " by replacing C23 with a 10pF ceramic capacitor"


Looking at my board it looks like i have a cermaci capacitor in C23 but am not sure of its value.


Also, something about a resistor leg that needs grounding?


What steps have you guys/gals taken to get rid of this pesky "digital line noise:?


Cheers,


Nate
