There's a dedicated category in the forums ( where you originally posted ) https://forums.sonicacademy.com/c/beta-tester-area/ana-2-beta and S.A team could also use other medias like emails to users or announcement via their social medias or the more recent Facebook Discussion Group https://www.facebook.com/groups/295362341294315/
Would likely depends of the importance of the Beta & the needs for testing, but S.A will let you know
The GUI displays a 49 keys layout keyboard covering 4 octaves ranging from C1 to C5. The keyboard Controls offer Mod Wheel or Pitch Bend Wheel and also other options but no octave change. The keyboard respond to octave change from a Midi controller but when you're out of the C1 / C5 range you won't see the notes. I think this is the default behavior and that's not possible to map via the Midi Assignments in the settings.
Don't find it that a big issue myself though
Now additionally ANA 2 shines with the very powerful Chord Memory Device or CMD that offer complex Chords maping on a single key across the all octaves. More about that in the manual : Section 13-CMD / Page 48.
