Trying to get rhythms quantized on a 6:4 grid in 4/4 time to see something like the viola part shown here. Trial and error to pick the correct quantization settings, whatever I picked was wrong, so naturally I press Cmd-Z to undo and try a different setting, only the wrong quantization won’t undo.
Vc1 is the MIDI recorded part I wanted to quantize.
Viola is what I just keyed it to show how I intended for it to look.
