The possibilities are almost endless. Not too difficult once you figure out the basics. The keyboard shortcuts are worth learning. Not really a game, but a great introduction into electronic music with a visual aspect not seen before, at least by me. Creating and changing the riffs with effects provided is somewhat daunting, and I have musical instrument and effects experience.
Graphics are good, visually pleasing.
The 3d videos that can be automatically generated to the created music or your own music cd's are kind of lame. Sound of most music riffs is excellent. Some have background noise and hiss that must be from the method of sampling.
