This is pretty much the solution to the feature request I created last year a Sample based synth engine.
This engine needs to make it on the Play+ too, it badly needs an advanced sample engine to be able to use samples for pad/atmosphere and soundscape sounds.
I could see me grabbing the Play+ again if this was the case, as it stands the OG Play is enough for my needs, but with the DWA engine it would make using melodic samples a hell of alot more fun on Play+
