I play in a live rock band but there are few songs we play where the electronica instrumentation is provided using MIDI files and the band plays to a click track. They are songs by Lady Gaga, Rihanna, Pink and Gwen Stephanie. We aren't cheating but just augmenting our playing with parts we just can't perform with our lineup. And you can bet that these artists also use some pre-recorded parts when playing live.

The audience loves that we can deliver convincing covers of these songs.
