Figure 6: Controlling the GUI
Each trackball controls the movement of a pointer on its respective GUI screen (see
Figure 6). Move your finger on the trackball to operate the pointer on its associated
GUI screen. The left trackball operates the mix bay GUI screen and the right one
operates the GUI screen in the master bay. Each trackball has two buttons, which have
similar functionality to the buttons on a PC/laptop mouse. The left button is used in
click and drag operations, while the right button is generally used for editing and finer
control operations.
Click
Moving the pointer to a specific point of the GUI screen and pressing the left button is
called “clicking”. This is fundamental to GUI operation and forms the basis of many of
its operations, such as switching a button on/off, selecting list and menu items, text
editing etc. Doing the same with the right button is called “right-clicking”.
Drag
Moving the pointer to a specific point of the GUI screen and then pressing the left
button while moving the pointer up/down/left/right is called “dragging”. Dragging is
used mainly to adjust control knobs and faders, and to move sliders (attached to
drop-down lists)—although it is also used to select blocks of connectors when patching
(see “To select a block of patch connectors in the From section” on page 75). The
pointer disappears when the control has been selected to show that it is ready for
adjustment.
