from what i've tested the bloc also stretches out the samples, except it would skip what it couldn't play in time. i guess doing it like that would be useful in some cases but you can still pitch down stuff using machiniste without it skipping anything. stil not really sure why you would do it this way
did you know the exact number values for changing pitch? I couldn't find stats on this anywhere. It seems like percentage to pitch is borderline impossible with every device calculating it differently
