Im not an expert hacker but I am wondering if anyone can make a simple application where it is just a keyboard that you tap the keys and it plays notes. It would also be very cool if you could do it with a guitar and literally strum the notes. Can anyone do this? Edit- So there have been drums and keyboards, but the problem I am finding is that it is way to quiet and there is no way to make it louder. Also there is no guitar like thing where you can actually play the cords. That would be awsome.
