OBERHEIM SYNTH

it is strange that its one whole board.

maybe re seat the connectors and see if it stays right for a while.  how are the data dacs set up on that machine? could it be that each board shares some of those global settings? 


i know that my ob8 does card/memory/recall stuff like that sometimes and i usually can to go through the split dual menus and then re tune the voices to get it to behave properly.

like the brains need to get jostled!

they are moody machines!

;-P

Subject: [oberheim] Intermittent OBXa filter issue


  
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
