I have reburnt the iso onto a new disk three times on two different writers and still the problem persists like:
1. locking up for up to a minute after pressing locate in seq mode.
2. FX assings disappearing while recording.
3. Left channel out cuts out and the sound I was playing is replaced with a flat piano wave with no EG or VCA setting just like the init sound you get on an M1 when the factory's are lost.
4. Combi's have some sounds missing using Karma but if you stop Karma and restart it again the missing sounds return.
5. In program mode sound names are blank from time to time but return if you switch to combi and then back to program again.
I must admit, I am expecting Viagra popup windows to appear on the touch screen next.

This is in no way a "Have A Go At Korg" post. I still love my Oasys as much as I love my CS80, and that's saying something as the guy's who know who I am will know what CS80's are for me.
Does anyone else have these kind of problem too or am I doing something really really stupid here
