Why can't I change software instruments in the PlugIn selector?
Running Garageband 10.2.0 on my MacBook Pro. After choosing a sound from the library, I can change/disable the audio effects as I see fit but not the actual instrument. I am using only the factory provided instruments, no third party AU plugins.
Here is a screenshot showing the plugin selector:
When I click on the right hand arrows to open up a menu of available instruments, nothing happens. The instrument field only changes when I select different sounds in the library. Is this normal? If not, how can I fix it?
MacBook Pro, OS X El Capitan (10.11.6)
