Custom Music Boxes

If anybody has worked with the music aspect in "Little Big Planet 2" my vision is very similar. A player could select the instrument and place it on a sequence. the BPM, echo time, volume, and other settings can be changed from the sequence box. the player can adjust the size of the sequencer and determine if it will loop or not. once they place an instrument on the sequencer, they can start to add notes to make a song. this works much like any MIDI file reader program would. here is a video that shows off the possibilities of a LBP2 sequencer system:

NOTE: If any of you have a PlayStation 3/Vita, I encourage you get this game, It is like a finished version of KoGaMa squished onto a 3-layer platform.
