OBERHEIM SYNTH

Thanks Flavio, it is good to know
So I “think” I fixed it..
Removed voice 3 and soldered a new dock for it.
Removed cleaned and reinserted all IC that were not soldered directly to the main board
Zeroed the DAC.
Initialized and reloaded the factory patches.
So far so good….

If you find out that some CEM has been gone - I'd have a couple spare.

Hi everybody.

I have been struggling with a matrix 1000 for a while.

Basically I replaced the battery and loaded the factory patches but when I play it, I can hear on all the patches that at a certain keyboard point, the volume of the patch jumps drastically.

It is not always on the same key, but it is always on the upper octave.

I tried to run the calibration, but it stays there forever, which makes me think there must be some issue with the CEM or maybe some of them do not make good contact.

Voice test shows all the voices play and the high volume issue affects all the voices equally.

Anybody experienced this?

Thanks
