re: X32 Discussion
Thanks for the response, Christian - I hope you're enjoying your BBQ and not too distracted by the thread 
So, I have the X32 connected to my computer via USB (to test the 32/32 audio and latency) - here's what I've found:
If I use MIDI-over-USB on the console, the audio I/O is brilliant. A bit more latency, but that's completely expected, given the nature of USB. But, when I try to carry the MIDI (remote) traffic over the same USB (even with no audio, or a reduced set of streams), I have problems switching banks, etc.
If I plug in my Saffire 6 USB, and direct the 5-pin DIN MIDI from the X32, through the Saffire Interface, then configure S1 to use the Saffire for the Mackie Ctrl connection (instead of the X_UF MIDI), everything works perfectly.
I haven't connected my Macbook Pro to the system yet to test MIDI-over-FiWi, but will test both the MIDI-over-FiWi and the MIDI-over-USB on that machine, to try and isolate it as a systemic problem with the X32, versus just an issue with my desktop OSX machine.
And yes, the 2nd boot of the X32 was to install 1.05 - installed and updated without issue. 
I'll update the thread with my testing results.
Enjoy the feast!
