Sergio, excellent first effort. More please?

I don't really hear a definite melody line or soloist. Try pressing the SOLOIST button and select one. A guitarist or fiddle solo would fit nicely.

Some styles (not all) include a medley feature which allows trading 4/8/16 etc. You might experiment with that feature also.

You can also create a custom medley several different ways, to detailed to cover here.

Grazie, amico.
