great that you got your setup working. let me just note for the record that the sync issues commonly reported have nothing to do with the sync feature in audio midi setup. sync in audio midi setup means that different sampling rates are…
thanks for your techical details. There's a funny thing about Audio-MIDI-Setup: in the german localisation the function I mentioned is called "drift correction" whereas in the english localisation it seems to be "resample". IMHO: makes quite a difference, doesn't it? We all know what resampling means, but drift correction rather sounds in my ears like a "software implementation of word clocking different sub devices within an aggregate audio device".
I stripped down my USB tree to keyboard, mouse, and Virus TI2 (on different ports, hubs) and still got frequent crackles - probably not a USB buffer problem then, rather an audio sync issue? As the crackles remotely sounded like former sync issues with Soundflower within my aggregate device I tried different settings for master clock and "drift correction" - and this did the job.
So, I think quite a lot of people on Mac talk about USB related problems whereas they should focus on their aggregate audio device settings.
PS: it really would be helpful if people gave more details about their setup instead of just complaining Virus TI doesn't work...
