A simple suggestion, just add a slider control that only moves when the joystick is moved in a direction. This will make it easy to fine tune and adjust values like the pitch of an instrument for example. The current best way to do this is via something like a Radial menu or axis controls which are both a bit difficult to deal with and operate. If there was instead a slider control that could be moved with the joystick directionally (not directly copying the joystick axis), it would work wonders, especially with some of my more complicated avatars. Also allow the user to place an icon underneath in case they want to label the item, although this should also be enabled for things like radial menus too.
