When moving tied notes by half steps with up/down arrow keys, notes do not sound
This is on 2.0 beta 1.
Steps to reproduce:
On a staff (I used guitar), create a half note. Select the half note, and then use the up and down arrow keys to move the note by half steps. Note that each time the note changes, the new pitch sounds.
Now create a tied note. I did this by inserting an eighth rest after the half note, then an eighth note on the and of 3 tied to a quarter note on 4. Leave note entry mode and click on the note head of the first note in the tie (the eighth note). Use the up and down arrow keys to move the note by half steps. Note that both notes in the tie move properly together, but the new pitch does not sound each time.
