I would like to know if there is yet an alternative to the 'piano roll' system for MIDI editing.
The problem with music notation software is having to pre-decide on a time signature and basing the actual durations on it, whereas the pitch system is pretty easy to use without rhythmic considerations!
This simply means being able to just add MIDI notes freely but see the pitches in positions relating to standard notation on a 'grande staff' instead of a piano keyboard note.
I suppose the standard staff lines (in relation to Middle C), but with a three colour system: black (natural) green (flat) and red (sharp) could be used along a C diatonic stave-grid to convey sharps + flats (rather than note-heads) which would mean no gaps between pitch events that need to be accounted for by symbols.
Unfortunately, most software has 'Middle C' (traditionally C4) as C3, but anyway.
Pitch notation is important for conceiving harmonies and part writing because a lot of theory is understood clearly through concepts that were learned on paper, especially advanced harmony and compositional technique.
By default the key could always be assumed to be C ...some jazz composers used to notate every accidental rather than paying attention to key signatures, so with simplified notation that would be pretty easy.
Also, if the software comes in the form of a notation editor with simplified rhythmic/durational markers, I think a system that uses a simplified standard pitch notation could be optional:

Does any alternatives exist? Any thoughts?
Many thanks!
