if i am using something like my mouse position to control the pitch of an oscillator, how do i reverse the numbers? For example if moving my mouse down is making the pitch go up, how do i make it pitch down instead?

Use [screensize] to get your screen dimensions, [mousestate] to get the coordinates of your mouse, and [!-] (using the screen height) to flip the mouse y coordinate.

You could also use a [scale] object to map things in reverse.
