Thanks Sherry. Here are 2 examples of what I would like to write & print out. I am not so interested in having the computer actually playing it for me. As you see a free form has to be adopted regarding note values.
In the 1st example, working on a piano solo reduction of Scheherazade from a score, the solo violin part has 4 beats in the bar , but the third & forth are in 3 groups of 3 each! Finally the last cadenza bar is written not only to indicate the freedom and expression of playing, but is in small notes - this is quite common.
The 2nd example from the 1st Chopin Nocturne, shows a group of 11 and 22 notes (bars 3&4). There are many more examples to be found - but this gives the general idea.
I hope Composer can cope with this.
