Chas...
Fortunally the train for the evaluation is passed..
Megaaudio.de already full tested the new Groove products and they have also on stock. http://www.megaaudio.de/newsletter/news/Liontracs_News_Dec09.html

Want to laugh?
removed the arranger styles module from the OS installer and we get the contract distribution.
Another probe that the arranger keyboards will dead really soon, they want only Sounds Workstation!
From April we start to shipping 50 groove every months..try to ask one to Megaaudio..
I'm not allowed anymore to sell my products in the whole north europe.

About the USB3 at this moment I can not offer, just the available hardware: http://www.youtube.com/watch?v=LoIbTz1-1RI

Is better that you wait the new Audya 2 for this all new hardware features..
Happy new year.
