Intermittent OBXa filter issue

2011-09-19 by Tim P

Hi all,
I was wondering if anyone has had this issue before and knew how to troubleshoot it.
Sometimes when I turn my OBXa on, half the voice cards (four, all on the same upper board) have an issue where the filter isn't bright enough or sounds like it is not opening up enough for the way the patches are supposed to sound. The cards on the lower tray sound fine.
This problem will crop up, last for a day or so and will go away for a while. Sometimes repeatedly turning the machine off and on a few times will clear it up.
I swapped the 3360 on the board in question and that didn't fix it. Anything else it could be on that upper board? Anyone else have the same problem?
Thanks,
Tim
