So got the new unit - works with no problems with the UC (and UFX, UCX and Babyface).

I just updated the firewire and USB drivers to the latest versions but those don't solve the problem.

Thanks, Jeff.

No, the hub trick stopped working unexpectedly yesterday morning, about two minutes before I was set for a phone interview with the head of Common Cause (an important domestic NGO). Fortunately, I have a backup system...

Subsequently, based on advice from Chris Ludwig, Synthax in CT, I've installed the latest USB and Firewire drivers from a couple days ago.

1) Testing with the Apple Thunderbolt/Firewire adapter:

     Totalmix opens and appears to function normally, as does Fireface settings (Firewire, not USB settings
     but I had to force quit the application after powering down and disconnecting the UCX).
     No input, however, to Adobe Audition, though the program says it sees the UCX; plus which
     the Audition playhead won't move.

2) Testing with USB directly into the Macbook Air USB 3.0 port:

     Totalmix opens and appears to function normally, as does Fireface USB settings.
     Initially Audition does not see the UCX. After hot unplugging and replugging in the USB cable Audition
     sees the UCX and will record normally on one channel (I have to wait until later today to test a second
     simultaneous channel from a phone line).

Given (2) above, in this round I did not re-test the USB 2.0 hub.

I have other unresolved issues connecting my 2012 Mac Pro while using Adobe Audition. But there, at least, I can record from the UCX via Firewire into Soundtrack Pro. I've tried, btw, to install Soundtrack Pro 3.0 onto my Macbook Air (and I suspect it might work better than Audition) but for some reason, although the install goes smoothly, the program won't load. Maybe something to do with 64 bit architecture? I mention this because I wonder whether that's where the other problems might be?

Just for confirmation, re the Macbook Air, I installed Audacity to see if it might see the UCX. Similarly to Audition, the program says it sees the UCX but cannot then record.

I'm no expert but my guess is that these are all driver related issues. I've had no response, btw, on the Adobe Audition forum regarding my question about Audition's compatibility with the RME UCX. Nevertheless, given that unplugging and replugging in a USB cable makes things "work" I'm guessing that that's not really Adobe's responsibility.

I would try Pro Tools, which I suspect might help things work better, but I'm hesitant to purchase a program that's otherwise so far above my needs.

Hi there,

I'm about to purchase the 11" 2012 model and was thinking of a babyface to go with it. What's the current status on mb air 2012 compatibility ?

Thank you,

Gideon
