XL Star + 8 bit A/D Converter Part 1 of 3

I found this really nifty device on a local auction site and decided to integrate it into my larger synth setup.

The box has 8 analog inputs that run through an ADC0809 chip.  This is an analog-digital converter that will send its output, an 8-bit digital word, to a serial port on the other end.

What I'm planning to do is use the XL-Star as a control device for the A/D converter by attaching LDRs to each of the 8 legs of the star.  Hopefully this will produce an interesting data stream for my shift registers to chew on.
