Well, add another item to the list for me. I now have a Mitchell Concert Ukulele, a present from my brother.
I actually don't use a keyboard. Well I do, my computers keyboard I use to type this. But the piano keyboards you can hook up to synthesia I don't use. If you want to get into computerized instruments, it would be cool to start here, it's where I started... http://www.pulseboy.com/
