I know nothing can replace the real teacher, but I'm not planning on becoming a master pianist.
Can anyone recommend me any good program that would teach everything from basic stuff like reading notes and pressing the right key, all the way to sight reading. I have a MIDI interface between my digital piano and the computer, so I'm looking for a program that utilizes that capability. Thanks.

There is a Learn at Home program from Simply Music.com that includes video, and audio teaching that will teach you how to put your hands on the piano and sound great and give you a start on a pretty impressive repertoire.

I own a program called "E-Media Piano and Keyboard"..... it is OK but what I don't like about it is the screens are "locked" as a window so it is constantly changing as you play. What I like about it is it "listens" to you play and has some very good video on the basics. I feel i out grew the program in 3-4 months, but it also could be I became more familiar with the keyboard and did not need the constant feedback as much as in the begining. It does take advantage of MIDI and interfaces with the computer very well, but you will need a keyboard close to a monitor to take advantage of all it will do.
