Many people seem to not realise that there is already an alternative to staff notation; it is called the piano roll. It has all the advantages that alternative notations propose (proportional intervals and note lengths), is already in widespread use, is available in all professional music software, and is by far simpler and easier to learn. For many professional musicians the piano roll may be the only type of notation they deal with on a regular basis.

Any eclectic modification of standard western notation therefore needs to justify itself not just against staff notation, but also the simple piano roll.
