I bought a Korg PA800 upgrade kit including a 256mg Ram module
on Mar 06, 2016 from a company in Turkey, name of vendor was neverendingstory77 which made a total of 14 sales and now is currently no longer a member of Ebay, anyhow to make a long story short, I got around to installing it on my M3 and the samples are distorting, no way of getting any money back and once again getting ripped off from someone who no longer is available, so buyer beware.
