Another fun feature of Theater Organs, invented by Robert Hope Jones, is the ‘Sostenuto’. This stop is available on the Great manual of the Rodgers 340 Theater Organ.
Sostenuto is a switch located on the Main expression shoe that will cause the notes on the Great manual to continue to sound for as long as the Sostenuto switch is held – even after the hand is removed from the keyboard.
Here’s a quick video to see it in action.
