A new model version that reads uncommon time signatures and lines without a clef
Our scanning model has been updated, with a focus on time signatures, clefs and multi-bar rests.
- More time signatures are read as printed. The model now knows 29 time signatures plus common and cut time. New this month: 6/4, 7/4, 8/4, 9/4, 10/8, 11/8, 13/8, 14/8, 15/8, 9/16, 11/16, 13/16, 15/16 and 17/16, common in folk, jazz and contemporary music. Before, they were replaced with a familiar one (10/8 came out as 12/8, 8/4 as 5/4), the bars no longer added up, and notes were removed to make them fit. See every notation scanning supports.
- Multi-bar rests keep their real length. In band and orchestra parts, a number above a long rest tells you how many bars to count. That number is now misread far less often. Before, a "10" could become 100, and your part ended up with dozens of extra empty bars.
- Lines without a clef stay at the right pitch. Many parts, especially jazz charts and older editions, print the clef only on the first line of the page. The model used to guess a clef for the other lines, and a wrong guess moved every note on the line up or down. Those lines now keep the clef of the line before.
- Fewer things that aren't on the page. A small "3" over a triplet is no longer read as a fingering, no octave line (8va) is added where none is printed, and a stave that is silent for a whole line is no longer filled with drum notes.
- More of your notes make it into the score. When a bar is read with more beats than its time signature allows, some notes have to be left out so the bar adds up. Since rhythms and time signatures are now read more accurately, this happens much less often: on the imports we tested, about 70% fewer notes went missing.
