OBERHEIM SYNTH

Congratulations on your new purchase! 
There is a self calibration and voice test mode in the Matrix1000. This 
is explained on page 39 in the manual. Select Ext. Funct. #7 and press 
enter. Test 0 will run the auto calibration routine. The display will 
show CAL and it takes a few seconds to run. This will calibrate the 
oscillators, filters, and VCA's. Test 1 will show the voice that is 
triggered. If you have a bad CEM3396 voice chip you will hear the 
difference. One of mine had  bit of noise for the attack portion of the 
envelope when all the other 5 voices sounded fine. Then you can replace 
the bad chip. I bought several from:  www.maad.net/ms6/index.html  
They were $18 US each or 6 for $90.00.

Let us know what you find, Fran
