14 Chapter 1 Using Logic
• If you press Option-Control, the mouse wheel can be used to zoom in/out in both
directions.
Note: Logic also supports mice with two wheels. The second wheel works like the first
wheel, but with interchanged axes.
Input Options
This section discusses the various methods available for interaction with parameters,
and data entry tasks.
Mouse Input
Checkboxes
Checkboxes are square boxes that are “checked” when you click them, in order to
activate an option (or function). Click the checkbox a second time to remove the
“check”, and deactivate the option.
Pull-Down Menus
Pull-down menus open when you click-hold on certain input fields or buttons. You can
select a function from within such menus by highlighting the desired item with the
mouse, and releasing the mouse button. If you wish to select an item that is outside
the visible section of the menu,
• move the mouse over the top or bottom edge of the menu; the further you move it,
the faster you will scroll through the menu.
• hold down Shift as you do this. You can then release the mouse button, and use the
scroll bar to the right of the pull-down menu to browse. When the mouse reaches
the entry you wish to use, release Shift.
Mouse as Slider
You can set most numerical parameters (even note values or names) by grabbing the
parameter value, and moving the mouse up or down. If the parameter consists of
several separate numbers (song position, for example), you can adjust each number
individually using this method.
