I have one hanging off the end of my keyboard, but since I put an extension cable on the keyboard it doesn't play anymore. Ever see "Once upon a time in Mexico". Watch the special features on how he made the film, you get to see in his studio. He scored it himself. FUCKING BAD ASS!! Right after that I went got a simple keyboard/piano combo. Haven't used it but a few times.
I wish I knew how to play.
This is what I have.
