Ric:

What do you do with the Rachmaninof Prelude in C# minor? (The only piece I ever played that needed the sostenuto).  After you play the low C# octaves, then hold the pedal, you DON'T want the other notes you play to continue as long as the C#s.  The whole point is to have notes that sustain, and other notes that don't.
