Distorted sound on Kurzweil SP6

[Blopacarde]

Hi everybody! I'm new here, looking for some help.

I have a Kurzweil SP6, and it´s making a distorted sound quite randomly. Sometimes works fine for a couple of days, and then starts with the problem, sometimes it stars a few minutes after it's turned on.

I upgraded de OS, and still makes the same problem, it looks like this when playing strings:

Please find attached a sample sound.

Thanks a lot for any help.

Really sorry no one has replied to this. I’m getting a similar problem with my sp6…

Check the power supply, in my case it was a low voltage problem.
