Hi,  Here is an interesting YouTube video that demonstrates a couple of
variations of a player piano, performed by British pianist & comedian
Rainer Hersch.  It ends with a duet played on a Yamaha [Disklavier]
digital player piano.  Pay special attention to the first demo with a
wooden programming system: https://www.youtube.com/watch?v=Mm3AlLjPVsM
