I have been using Logic and its ancestor Notator Creator since the mid-80s. I will admit that I use it a lot for scoring as well as for arranging and composing and I am told that as a scoring package it does not work as well as Sibelius. Has Apple conceded that area? The notation aspect of Logic seems not to have changed much in successive versions and there are significant weaknesses. One area which frustrates me is that we were taught that a dotted note at the beginning of a beat is FOLLOWED by a note (NOT DOTTED) which makes its rhythmic value up to a full beat or a subdivision of the beat. In practice it means that a beat grouping NEVER finishes with a dotted note unless that note itself is of a value of one full beat. For example- I am trying precisely to notate "mordents" for one of my pupils rather than relying on rather imprecise "ornament" superscript. I am writing in 12/8. The basic notation needed without ornament is 1/4 followed by 1/8. (i.e. one beat in compound 12/8) I need to write two 1/32 notes (the mordent ) at the beginning of the 1/4. This should then be followed by a 1/16 note tied to an 1/8 note to make up the 1/4. Logic insists on following the 1/32 notes with a dotted 1/8 and then writes the following discrete 1/8. This isn't just confusing, it's notationally incorrect. If anyone can understand these ramblings of a diseased mind and knows how I can make the program work correctly I shall be eternally grateful. It offends me, as a teacher, to hand my pupils material that I know to be incorrect because I can't correct it. I know- lighten up!!!!!
