Never has been a way to control transpose from the grid but for the others, on a 128 grid, it’s these buttons. Mod 2 is top row button 8 I believe.
13 (with mod 2 held) global octave -
14 (with mod 2 held) global octave +
15 (with mod 2 held) global reverse
And few more. There several others in the manual.
9 (with mod 3 held) - step length page
10 (with mod 3 held) - reverse page
11 (with mod 3 held) - group page (columns 1-6 = groups, 7-8 = row vol, 9-12 = play mode)
12 (with mod 3 held) - octave page
(pages are momentary if you keep holding mod 3 after selecting)
15 (with mod 3 held) - set next tempo
Mods 3+4 are top row buttons 13+14
