Windows users, please see: Compatibility with Kontakt 7 Player and Other VST3 libraries (Windows)
When trying to open the built-in Kontakt 7 plug-in viewer, users may be faced with an unresponsive window that is smaller than normal and cannot be enlarged. See the image below for an example:
To fix this issue, you will need to adjust the view settings of Kontakt using another DAW.
1. Quit Finale.
2. Open your DAW (e.g. Logic, Garageband, etc.), create a new instrument track, and load Kontakt 7 into it.
3. Open the Kontakt 7 plug-in and select Rack View from the View menu.
4. Return to the View menu and select Set current view as default.
5. Quit your DAW.
6. Relaunch Finale and open a file using Kontakt 7.
7. Choose MIDI/Audio > Audio Units Banks and Effects.
8. Click the Pencil icon next to Kontakt 7 in the Instrument column. The full plug-in is now visible in the Audio Unit Viewer. (If you select Edit Player in the Sound column of ScoreManager, it will also be visible there).
