I am about to install the latest version of Dorico Pro 3. (I am a Dorico Pro 2 user.)
Does the 9.34 GB Sounds Installer replace that of Dorico Pro 2? If I leave both programs installed on my Mac, will there be 2 different sound libraries? (Disk space on my MacBook Pro is at a premium.)
The sound installer does include new (Soundiron Choral) sounds and (IIRC) an updated version of the Sonic player. You should install it. It should overwrite any previously installed duplicate HALion sound files.
