Sound Browser
The Sound Browser is the commonly used way to load a new sound from
the library.
The browser lists all available sounds within a bank. To change the bank,
just click on the bank name in the lower middle display. The last loaded
sound (the name you see in the sound display at the bottom of the page) is
highlighted in the list of sounds.
Whenever you click on a sounds name, it is loaded. Right of the sound
name is the rating you gave to a sound (if you like to). By default all sounds
are unrated. To change a rating just click on it.
To only see sounds with a certain rating you can select a range in the filter
shown on the top right. If you set e.g. 3 stars and 5 stars only sounds with
3, 4 and 5 stars rating are shown. You can invert the search by setting e.g.
4 stars and 2 stars, than every sound without rating or a rating of 1 star or 5
stars is shown.
Depending on the range you choose and the rating of the sounds in a bank
you might end up seeing no sounds at all. To see all sounds in a bank just
revert to the full filter range (unrated to 5 stars).
