This
video shows a performance using Groovyband Live! + MODX8.
The piece ("Odissea Veneziana") was very famous in Italy (and Europe) in the 80s. The band Rondò Veneziano (was actually a composer + various classical orchestra players) did a remake of Venetian baroque music of the XVIII century.
All their pieces are actually original and written nowadays, but in the baroque Venetian style (which was actually spread through all Europe and played at King's courts, such as Versailles in France).
The player in this video triggers fill-ins using the touch screen. He could have used as well the MODX physical buttons above his left hand (one of them is red lit), or any other midi physical controller USB connected to the tablet.
