Here you see the standard 3 sounds as 3 folders, 0, 1 and 2
Either edit the contents of these or create a new folder.
I created a new key called 3
In here, three string values were created,
(default) which defines the name of the sound
in - sets the sound when the keyboards closes
out - sets the sounds when the keyboard opens.
For instance, in the key 3 i have
(Default) set as a string value of Dogbark
in set as a string value of dogbark.wav
out set as a string value of dogbark.wav
Now I can select the dogbark as the keyboard sliding sound.
Sound files need to be in the Windows Folder in wav format.
Right now, Mine is barking. Gonna see what I can find to change it to later.
