Brian:

Perhaps I'm not understanding your question correctly, but can you try this in the Piano Roll window?

- Let's say that the notes you want to "glue together" are all "C5"
- In the Piano Roll window, make sure you have the required track selected
(i.e. in your case, the "Strings" track)
- Left click on the C5 piano key at the far left of the Piano Roll window
- That selects ALL the C5 notes that will be played on the Strings track
(they will all turn red)
- Hold down the Shift key and move your cursor to end of (that is the right-hand
side of) the first of your C5 notes.
- The cursor will change to a right-pointing arrow
- Left click anywhere near the end of that C5 note, and drag it to the right
- That will lengthen not only the note you clicked on, but ALL the C5 notes on
your Strings track.

Is that what you are trying to do?
Good luck!
