Workarounds for UNDO?

[MsKorg]

Hi everyone. A new Krome owner here.

Most you are professional or advanced keyboard players, I'm not
I really like the Krome workflow with the touch screen, but I do miss a undo button. I know you can quantize and edit your errors before and afterwards but I wonder is there some reasonable workarounds to undo the errors? Or is there a hidden undo command I've yet to find? Thanks!

The "Compare" button allows a return to the sound before editing. Any changes made to the original sound become the new edit.

There is no mullti-level undo, as such, although the piano roll has an undo function, though this is also only one level. Alternatively do regular saves to different locations.
