I just got off the phone with Gary and he said GPO works best with Windows XP currently, but will still function in DP4 and OSX. He didn\'t elaborate on many specifics other than there are some CPU effiency issues, and some audio crackles which I already get with DP4. It sounds like it will work alright in OSX, but just not as well as in Windows XP at this point in time--as I understood him. Is there anyone using GPO with DP 4.11 and Panther that could share your experience? I also have a laptop with an AMD Athlon 2000 running XP. Would it be better to run GPO on the laptop and treat it like a standalone synth module? I actually ordered GPO today, but I just want to make sure I\'ll have success using it with DP.
