You can still get the legacy blocks if you go through the options but i just don't like it either way now. It's so easy to get each track out of sync with the rest i find myself having to do everything individually, then deleting them all in the playlist then reapplying them to the playlist and rearranging it all just so it plays properly. At least in FL9 it was easy enough to delete and reapply what you wanted.
FL Studio is worth buying cause if you buy the Download version you get a lifetime Update fpr free... so the longer u Use FL STUDIO the longer its value will be for you... but i find it rather confusing that some Clicks and Moves to edit stuff constatntly change with each new version... its like re-learning some basic things over and over again while using this daw...
