And for JJJ....
Here is a track I put together - just for you

this uses 5 different Amber tracks. Changes 2 measures at a time.
first a "picking" pattern.
add a strum next 2 measures.
add 2 more (panned L an R)
add another
and then add UJAM Rowdy 2 bass at the end.
http://www.floydjane.com/Songs/Amber.htm.I built the first track by playing and recording the chords (single keys) and key switches (pretty random, but in time with the music.
I exported that as a stem (Studio One) and loaded it back in.
I then simply changed to another style and - using the same MIDI pattern - exported another stem... 5 times.
I used the same MIDI pattern for the bass (Rowdy 2)
(I used the same MIDI pattern in Sparkle 2 and generated 11 tracks of electric guitar - but they are not in this mix)
