Sound Browser and Mini Browser
The Loop Browser and Sound Browser show different views of the MediaBay.
The Loop Browser lets you quickly browse your loops, for example, audio files and MIDI loops.
The Sound Browser lets you quickly search sounds. By default, it is set to display track presets and plug-in presets.
These browser windows offer the same functions as the MediaBay, for example, you can specify different browse locations, define searches, set up the available panes, etc.
