Key repeat glitch with Cynthcart (Page 1) - Commodore Computers - Forums

I've had this issue on and off since I got this thing on Dec 30 but now it seems to be constant.
While running CynthCart V1.1 a note will constantly re-trigger after it has finished it's decay.
If I don't trigger a not myself it will just do it it's self and/or it will just trigger a random low note over and over.
I did a simple audio mod, 1uf cap to 100k resistor to ground then wired to a 1/4".
But like I said I was having this problem on and off before I did the mod.
Any idea what is going on here? Is my SID screwed up? I don't mind having to buy another SID but I'd like to not make this mistake again.
Thanks!

I never had a problem like this but I suppose it might also be a keyboard issue... maybe try cleaning it inside and check the keyboard contacts?

Good call. Will do.

Is there anything plugged into the joystick ports?
They can interfere with the keyboard sometimes.

There is not. But when there is it makes it worse. Can't remember how exactly right now.
I'm playing with it right now and I took the cart out while running and it seems to be working now. I can't believe that this would be any sort of permanent fix though.
