Here is my next problem:
While the playback sound in Dorico did work the first day it does not work anymore now (with same test project).
• During playback only in the first Mixer channel strip I can see an activity (in this test project I have only one player). No activity in the Output strip and in the Reverb strip (as it was in the first day).
• Also in the first day the Halion window showed up. Now it isn’t visible anymore. How can I open it?
