Thank you! That explains it. In almost all places, the manual just says this:
“Press [TRIG 9–16] to select sound bank A–H.” - And this worked pre-1.01
Elektron are really the kings of key combinations! I should try to glue all those keys down (“YES” so it’ll always play my sounds when sequencing, “BANK” so it’ll always switch banks etc.) and see what happens
