I've got a Digi001 and PTLE 6.1. I tried Core Audio. Don't like it. I'd rather use my little Tivoli Audio desktop speakers connected to the Mac's output for iTunes and any other software that I need to use, and I'll let PTLE control the Digi001's outputs. Is there a de-install process or does one just ignore using the Digi hardware in the Sound Menu? Thanks. homershines
