The World's First MachineLearning-enabled musical keyboard !?!

Today Amazon released AWS DeepComposer which is a keyboard that will let you "create a melody that will transform into a completely original song in seconds".

To me it looks like an Arturia Keystep knock-off.  I'm still puzzling over whether or not there's any special ML-related features - or is it just a MIDI keyboard that comes with some AWS credits. Anyone with any insights, please let me know.
