I run Finale 26 on an iMac IOS 10.15.7 (Catalina).  My articulations (string tremolos and piano Pedals, for instance) do not sound. Cannot say if all the articulation are like this, those aforementioned, and accents and trills also do not sound. Addirtionally, all output is now out of one stereo channel with the other one dead.   The stereo function works on iMac streaming of music.  Anybody with any ideas - most welcome to hear.
