For simplicity I use IRealPro App in my Ipad. It takes me 10 to 15 minutes to enter a song chord by chord. There are different styles which use Bass, drum, piano., which are changeable to other instruments. Transpose and tempo controls. It’s simple but because it is simple it’s fun. The styles are not great for rock.
I solo with my Taylor guitar and sing.
When I need more I have the midi files and Mp3 which I recorded on my keyboard-- also in my Ipad.

Ipad and amp. battery and Blue Tooth battery – no wires. It is great for woodshedding a song.

And it’s great when I am playing just for me.
