The new update 1.2 for Launchpad Pro MK3 users adds some special new features that aim to add nuance and uniqueness to sequencer patterns and re-open the door to lightshow perfromances amongst other possibilities.
Here's what Novation tells us about the 1.2 update:
"Launchpad Pro [MK3] users now get Unquantised Recording to create out-of-this-world, off-grid beats, as well as a new feature that lets you perform and record sequences with even more intricacy and nuance than before. There’s also the ability to set the threshold of the trigger pads, to tailor Launchpad Pro to your unique playing style. Lastly, Legacy Mode re-introduces the User layout of the original Launchpad Pro, which opens the door to a world of legacy applications and lightshow performances."
(Note that this update only applies to Launchpad Pro [MK3]; previous versions of Launchpad or Launchpad Pro are not affected.)
