General Discussion / MIDI Import has bug when part rhythms differ: not worthy of Noteworthy!
This is a huge problem, and the solution provided by Noteworthy is to split the track into two staffs at particular pitch. It will even do an analysis before you import and find the pitch that results in the fewest mistakes. You can even set your own pitch ranges for each staff. This helps for some kinds of music, but vocal music, and a lot of other music does not work that way. You wind-up with each part split between staffs, which is not useful for most purposes.
I don't understand why the import can't bring in the notes as indicated by the MIDI events. You are allowed to enter two different note values into a chord when you are manually entering the music. Noteworthy notates it as stem-up and stem-down. The "chord" is logically given the note value of the smaller (i.e. if you put a half with a quarter takes the horizontal space of the quarter note). However, it will sound the full value when played as long as there are notes or rests to take up the full value of the time signature. This should always be true. Even if one part starts a measure with a quarter rest, and the other part with a half note, and the part starting with the rest then has a quarter note, the half note can be notated as tied quarter notes, the second of which is part of a chord with the other part. So, you can always implicitly get a rest when needed if done in this way, even though Noteworthy does not have the full concept of parts (including rests) in a single staff.
So, Noteworthy Composer can notate two parts with different rhythms on the same staff. The only problem is that the printed sheet music would not explicitly show some of the rests in fairly rare cases. However, the playback would be perfect. Why can't Noteworthy import what it can notate? You can try notating two parts with different rhythms, export to MIDI, import, and see what happens.
So, what excuse can the Noteworthy people have for having such a broken import? It does not require heuristics or artificial intelligence, it is simple. Why not just import the music as indicated in the MIDI events? Or, at least have the option of importing as written? As long as it has only two parts per channel, not much can go wrong. The vast majority of vocal sheet music (as read in by PhotoScoreMIDI or another product) has two parts per staff, and therefore two parts per MIDI channel, and those parts often have different rhythms. The provided splitting of the track by pitch is not workable. As it stands now you have to import into one staff and then manually go through the score finding all the places where the rhythm differs and fix it. What a headache. Really this should be considered a bug report and not an enhancement request.
