That would be neat if it worked again as it should in 10.9. My Firewire Duet was a disaster with 10.8.. It was so bad I bought an all new interface. I did hold onto the Duet though..
Well, I installed Mavericks and the Duet firmware update. Output works as usual but my inputs are basically gone. I can't record audio. In Logic under Preferences>Audio>Inputs it only lists surround sound options, not stereo. Anybody know any solutions? I felt confident upgrading since there was a firmware update but now I'm screwed and I can't reinstall the old firmware because it doesn't support Mavericks. Great!
