Need a simple, midi sequencing, music studio program

[JCase]

My dad is looking for a program to replace Cybersound Studio 3.0, an old midi program that won't run on any of our new machines. He needs something with a simple interface, built in drum tracks (or ability to create his own with live drum sounds), and not much more. He's tried using Cakewalk, but it's basically too powerful for what he's trying to do. Any suggestions?
