Thanks Nick, but that picture was a bit too small for me to see it in detail. It looks similar to the method used by Sibelius though.

I still need to keep the bend up and down all within one note if possible, so that I can use the Note Style facility, otherwise the program logic gets really messy. I need to consider other program functions, such as chord generation, which are affected by tied notes.

Note styles give the user complete control over all the MIDI parameters available, although there are some predefined examples supplied with HARMONY. The last item within a style usually needs to reset the parameters, particularly the 'pitch wheel', otherwise the effects are carried over to the following note(s).

I think I may have to go with the curved up arrow (and back down if appropriate), even if it means more work.
