Hello. Just installed the new Steinway Synchron keyboard. I already had the Yamaha installed. Using Mac 10.12.6, Digital Performer 9. Installed the latest version of Synchron keyboards. I notice the piano icon that toggles between the two keyboards. The Yamaha works fine, as before. The Steinway, no sound. In the same setup instance the Yamaha works, but the Steinway does not. Any idea what I'm missing / haven't done? I seem to be able to load the sound into the Steinway (get the download icon briefly, etc.) but no sound. Suggestions?
Thank you.
