Good point on the oscillator. I just assumed since the onboard (on my board that is) oscillator is 256x the sampling rate that it would work. I was beginning to think along those lines myself. I read the post on the mainboard crystal, but will reread it. I will also try tapping into the Empeg's Xtal.

I will post the pin config later today and also a schematic cludged up from the Crystal PDF. Unfortunately, I don't have a scope that works properly. I have been connecting the output on the board to a "Flying Cow" D/A/D converter. It has a valid data indicator, which never illuminates when the output board is connected to it. It's beginning to sound as if I have bitten off more than I can chew. But I'll keep trying.
