I wanted to try a different temperament in GrandOrgue. After selecting one in the menu, all stops (16', 8', 4', 2', 1', 2 2/3', ...) sounded like 8'.
I tested some more organs. The problem occurred for:
- Rotterdam Demo 2 manual.organ
- GO(1280x800) Rotterdam-Marcussen-demo.organ
- cean rotterdam.organ
- Utrecht Demo.organ
For these organs, there is no problem with changing the temperament:
Is this a known issue? Is it possible to correct the organ definition? Or is it related to the samples?
