Not to be too negative here, but I hope and pray that schools and colleges are the LAST place that keyboards like this appear.......

You don't learn about great choral music by playing it on a keyboard, you learn it by participating in a REAL choir....... I guarantee, from listening to him play, Roland's demonstrator has worked with many great choirs to get that ability. Sure, once out of college or school, there's a use for it, but you don't learn about good voice leading and dynamics, and all the 'tricks' of great gospel and other choir music without participating in a real choir.
