"DAC Offset" to control pitch ? "DAC Full Scale" to control stretching ?

2007-05-02 by gil_we

Ive just calibrated my OBXa and there is some issue -

C5 is in the correct pitch when master Tune is at 12 o'clock,
but the stretching is too wide so the lower octaves are much lower than 
standard tune. 

There are two trimpots on the main DAC board, one is the 
"DAC Offset" and the other is "DAC Full Scale"...

Does is make sense that the "DAC Offset" is the main tune (pitch) 
control and the "DAC Full Scale" controls the  stretching ?

Thanks
