|A special feature of this pipe organ is called the Sostenuto. Once it is turned on, the organ will keep holding the keys that you pressed until you press another note or chord – very useful in improvisation when you are playing more notes than the number of fingers you have. To activate Sostenuto, push the Sost. button.
The buttons on the Console Page controls the keyboard above (as seen on the picture) while on the Center Page they control the division nearby regardless of keyboard assignment.
Note that when the keyboard assignment changes, the Sostenuto will turn off.
