Love how easy Ed Diaz & others demonstrates how to create a multitrack song.. Nice goto sounds, Organs, drawbars, Piano, EPiano, Synth, Strings, etc,.. easy to edit on the fly also,....if you don't need styles and play with SMF or custom backing tracks, loops, this is a nice lightweight only 12Lbs powerful KB to gig with for sure,.. at a great price too..iPad friendly. Ac or battery too.
