user wants a -1 ms offset
user selects the notes
he double clicks on note property "Start"
instead of "1.1.1.00" etc he enters "-1ms"
bitwig offsets it 1ms to the left
-500samples, -2beats, +3beats, you get it
done
ps: yeah at ppq resolution only, but should be enough (?). and nobody is forced to enter +/- values, no feature drifting.
