ZERO 4 problem HELP !!!

[Korg1906]

ZERO 4 with Ableton.
Version 1.6 instaled on ZERO 4, firewire problem with XpSP2 solved .

I'm posting this to see if any user had a problem with Korg 4 or 8 in Ableton.

As reading the posts I saw that many people have problems with noise and hiss . I have a diferent problem. There's no hiss , it works fine but , when you are searching samples thru ableton the mixer chanel one goes green and you hear a high constant pink sound . In that moment Ableton stops to respond as same as ZERO 4. You need to restart everything to work again.
There's no definite action to make this pink noise , but in 80% comes when you 're browsing thru samples.
That 20 % comes when you play something. There's no exact time when this happens , sometimes after 15 minutes sometimes after 2 hours of constant working with ableton and zero 4.

If any has a idea to solve this please post .

P.S. I'm starting to get sick of Korg's new products that are not tested and done thru the end.
