Creates symmetrical waveforms by copying the first half of the sample into the other half with inverted values. Sample length (frame amount) must be even.
Changing the selected sample turns it off.
EDIT: old version of the tool did not crate symmetrical waveforms, not sure how I didn't notice that. ctrl-f "smp_len - f+1" in the main.lua and change it to what you want, I find doing it all the time.
BUG: While the tool is working you wont be able to undo at all, so disable it first. (by changing the selected instrument/sample.
