I thought I described exactly what you wanted to do just a different approch instead of copying the note, you just draw it over the ghosted note of the original. You can quickly deal with as many tracks as you like. It takes seconds to do this if you get in the groove, just like any task on a computer, practice makes things go fast.. This also gives me the option of drawing the notes as different values or even splittting a 1/4 note into two 1/8 notes for a certain instrument. The smart tool is brilliant for this and using snap and note value settings etc you get what you are asking for no problem.
Fact is that usingany software is it rarely will do things the way
you think it's should, so we adapt to how the programer though it should work,, but it does work.
