Hi, 

A very strange situation occurred with Finale 26. I work on an orchestral piece and all works well till strings stop to play in measure 74. Only this one and then back to normal in measure 75. I first went to View/Show/Hidden notes and rests. Nothing there. Next I tried to erase and copy or write again. No success either. I have inserted a measure next to it and before it and then write some notes inside. Still no sound. 

In fact I should say that I hear some sound at a ppppppp level.

Next, I've erased volume and velocity midi data in all the measure around in this section with no result.

Last but even stranger, I put a ffff on the first note that doesn't sound and, surprise, It sounds as loud as it should. I thought, then I could just delete the ffff and bingo, everything would be back to normal. Well no, everything is back to strange.

I hope someone here can help me with this very strange situation.
