I installed Ezkeys – pipe organ in Demo-Mode. Both Versions – Vst and Stand-alone do the same:
Changing the initial register ‘plenum’ to any other results in a sound of a 8′-Flute. Changing forward and backward to other registers the sound stays the same.
Only the fx-part reacts as selected.
I checked the the installation, placement of the library and so on; can’t find a mistake.
Searched your forum, couldn’t find a hint.
Very strange, can’t imagine that I should be the first running in that issue.
