Every once in a while we run across a cool integration of music and technology.
There is a cool robot playing the saxophone or another improvising drum beats real time. Moreover, Guitar Hero has combined true art with Peavey, the iBand was made for the iPhone to create actual music, a virtual drumset to be used with your iPod is available, and many more.
The MidiPiano Plugin may not be new but is still really cool. Using your regular computer keyboard, you can play every note or key of the piano.
Of course, it would take some time to get used to the placement of the keys, let alone get good at it. Still, it is pretty great for the musician who would either like a break from the real physical piano or perhaps cannot afford one. Furthermore, it would also help any train their ears and abilities…the rest is up to practice.
