When I go to the presets manager and filter the presets by "All banks" and "Favourites only" I can then use the arrows in the main window to cycle through all my favourite presets (including custom ones), but when I swipe sideways on the piano images in the UI pianoteq only cycles through the default presets ignoring any custom ones that I have favourited.

Is this by design? I don't remember this behaviour under Linux in Pianoteq 8...
