A short remark from a NoteEdit developer about this, because it is
the most basic statement in this mail. Many times I was prompted
to join other open musical score editor projects. And the
question arises: "Why so many different projects?". And this sentence
gives me the opportunity to declare why I didn't:
In other projects the MIDI related way of thinking dominates.
The score editor is regarded as an appendix.
In my opinion, this is a basic error. The internal
data structures must represent the score and the midi data
must be derived from these data. Why: The mapping from
score to midi is unique mapping. But the reverse mapping isn't unique.
And another aspect: From the very beginning it was quite
clear to me: The main problem is grouping: The are
vertical groups (chords) and horizontal groups
(beams, slurs, ties, tuplets). Every note can be a member of
any of these groups, even simultaniously.
The grouping phenomenon is completely unknown
to the MIDI world. Thus, I think: Any MIDI based
data design won't succeed and leads to the effects described
above.
