Subject: Re: [korgpolyex] Poly800 button issue and Atomahawk question

Hello Rob,
I advise you to check the cable connections and input pin, possibly clean with Flux for contacts eletttrici ..
at worst you have to replace the integrated 40HC240.
if you can not find the specific integrated you can replace it with the integrated 74HC240 ..
I recently had to sosituirlo even I on my Poly 800 and it works perfectly.

let us know if you solved.

Hello people

I have recently purchased a Korg Poly800 from eBay but it has a few issues unfortunately. The main one that is troubling me is the 8 button does not work. I opened the unit up and checked if it was a contact issue, but it is the actual button on the board that does not work. Has anyone had a similar issue before? There is another issue with the keys, every 8th key does not sound. I believe this is down to the IC33 chip, is there any way the two faults could be related?

Also I am interested in the Atomahawk upgrade to give me full MIDI control over the unit. However my soldering skills are pretty non existent. Is there any way of getting a pre-soldered version?

Any advice would be greatly appreciated


Cheers
Rob
