I thought about having different rhythm patterns being played on the same guitar so you can change at any bar with F5 or F8 but it will just blend in without having a different tone from another guitar.
At the moment you only have A and B pattern options for an instrument but if you had a large choice of different patterns on the same guitar, like it can play finger picking then into a strum pattern then a held chord strum and slow strum.
This way you can arrange the playing in the sections how you like and not just A pattern B pattern.

Like the demo below, so you have more control of what's being played where. I don't need to change the part marker, like in RealDrums with lots of variations to choose from, same instrument just different pattern.
Uniqueness is what you need rather than using the same "Style" as others use in their songs.
