Hi. This may not have the "flash" or sex appeal of many of today's 'games', but I purchase a subscription for each of my students to "SmartMusic". However, the 'controller' is your actual instrument. It gives you immediate feedback on pitch and rhythm and when set up as an assignment, I (teacher) can listen to the performance and then can evaluate tone, musicality, interpretation, etc. Most major method books are all available, many pieces of traditional and new school literature is available for play-along .... Well, those of you who know, know what a wealth of material is available.
No I do not work for them and I see no kick backs.
IMO- best $40/year spent. I use it at work, my daughter and I use it at home. You can use multiple instruments....
Yeah I could go on.
