Hi,
This is a user to user forum. There are no Line 6 staff here and only very occasionally do they visit these forums - (See the “sticky comment” in the black banner stripe at the top of this page entitled “Welcome to the Line 6 forums”).
If you want to know what is happening in Line 6 world, you need to check over on The Gear Page, in the Digital and Modeling section.
IIRC, there has been recent rumours of an imminent release of a Native software version of the new Stadium hardware. How true it is, I don’t know, but you can forget any major advances with the first generation version of Native.
If you want to use NAM A2 download the updated plugin and patch it in on your DAW.
Hope this helps/makes sense.
