I feel like it’s definitely been brought up before but the fact that we can’t transpose samples in the Audio Editor surprises me. Without this feature, playing in-key with the Chromatic Mode is pretty difficult because the pseudo-black-and-white keys don’t correspond to the actual note. Even something as cheap and simple as the PO-33 has this feature.
EDIT: resampling is among one of the tricks to get past this but IMO this falls in the category of a workaround that honestly shouldn’t be needed for such a basic function
