Sudden program changes
 

Hi there,

I just purchased a second hand Virus B Desktop from eBay and overall I'm pretty impressed by the machine and it's sound.

Unfortunately, sometimes it seems to act a little buggy.

For example, while stepping through the presets, playing some notes and tweaking knobs, sometimes an automatic program change occurs, although I did not consciously initiate it. It just happens while I'm playing.

Now, I'd like to know, if this this a know bug or something I may have forced accidentally? I'm using the latest Virus OS, Logic Pro 9 with an ESI M4U XL midi interface.

Thank you.

Is this QBit from Nebraska?
