Firslty, don't be fooled by the name. RGB MusicLab has nothing to do with conventional music composition - it has more to do with converting images into sounds.
RGB MusicLab converts the primary colors Red, Green and Blue (RGB) into a chromatic scale sounds. It works by reading the red, green and blue pixels from the top-left to the bottom-right of an image, and composing music accordingly. One pixel creates a harmony of three notes and the length of note is determined by brightness of the pixel.
The theory is, because every image is composed different, each will create a different tune. To get started, simply drag and drop a JPEG image of any resolution into the right image panel. A mosaic of the image is instantly created on the left panel. Select the kind of instruments you'd like to represent your image (such as Grand Piano, Honkeytonk Piano and Clavi) and click on 'Create RGB Music'. A progress bar appears while it briefly processes the image and then you can click 'Play' to listen your music.
The results, unfortunately, usually sound horrendous. It sounds like a random cacophony of pianos being smashed about and isn't exactly music to the ears. I have no idea how it would even be possible to make something that sounded mildly pleasant from simply the pixels in an image. If, for some reason, you do like the music your image has created, you can save it to MIDI file.
RGB MusicLab is an interesting concept and it's easy to use, but don't expect to be creating sweet music.
