I checked it out an have it on order. The song choice has a few song of interest to me. The Arcade games I'll try. Maybe just for a change of pace.
But, what intrigues me is the SESSION feature.
Look like I'll be playing with my own band..LOL
You can set up a full band to play with. Drums, bass, rhythm guitar and keyboard. 75 instruments in all to chose from.
You pick the key and scale you want to play in and it show the note to play.
Here the link to the session demo in case I'm explaining it wrong.
