undo/redo in the waveform editor

Hello! Apologies if this has been posted before, but it’s disturbing my workflow more and more, so I thought I’d post here.

This was an issue on Renoise 2.8x as well as in the 3 beta.

Basically any edits I try to undo while editing a waveform (fade in/out, cut, paste) do not undo. Instead, in the status bar, I can see it’s applying undo events to stuff I did outside of the waveform editor (so for instance if I edit the pattern, then switch to the waveform editor a cut a bit of a sample, then undo, I see the statusbar mention that the pattern edit was un-done … not the waveform edit as expected).

Thanks in advance for any help!

Is the “Undo” button enabled (Somewhere bottom left corner of the sample editor)? It works fine for me in 2.8.1 and r3


Holy crap, how have i never noticed that?
