If I create a new project in cubase 15, import an audio track and then insert the UAD Ocean way studio plugin, the audio does not sound. If later I save the session and reopen it then I do have sound. This only happens to me with Cubase 15, in Cubase 14 it doesn’t happen, and it only happens to me with this plugin.
A friend also has Mac mini M4, Cubase 15 and the same plugin and exactly the same thing happens to him. It doesn’t happen to him in Cubase 14.
