complete

> Windows.) A new point will appear where that tone is on the curve.

> 2. With the arrow keys, move the curve point. It will increment by twos as

click the

value
> highlights below the curve. Now when you press the arrow keys, it will

intuitive,

points.

And if you're using Windows with a wheel mouse, it even easier. Just click
inside the box and roll the wheel up or down. The value will increment in
single units.
