OK, I have an M-Audio midi interface that is like a keyboard. It hooks up through the USb port on my computer. What I am looking for now is software that will emulate a typical keyboard on the computer. I pretty much want to learn how to play piano with my midi controller. Is there a software out there I can use, or do I need to get some external device and use that? I know I can hook it up to my drum machine and then use my drums machine from the midi controller, but I kinda just want some software to goof around with.
