"The Misa digital guitar is a MIDI controller. It must be plugged into a MIDI capable sound module. The sound of this instrument is limited only by what you connect to it. Specifications: Linux kernel 2.6.31 (Gentoo); 24 frets; touchscreen; MIDI out; Ethernet; and SSH server."

"MVC is all about separation of concerns. […] Now, here's the test of a true MVC design: the program should in essence be fully functional even without a View/Controller attached. OK, the outside world will have trouble interacting with it in that form, but as long as one knows the appropriate Model API incantations, the program will hold and manipulate data as normal."

Very good description of MVC
