iConnectivity is still working on calling CATALINA fully good to go but if you are there and want to use the applications but they aren't open, follow these steps below.
Here's the error when opening the apps
Go to System Prefs
Security and Privacy
Then select Cancel on the original error message and this option will appear in the General tab in the Security System Pref
Select Open Anyway and it will open.
If you use iConfig you will also get this message.
This is mostly for exporting MIDI presets form iConfig, if you use that option.
