Working with the controls
The control surface is populated with many familiar analogue-type controls. However,
the GUI-related ones, such as the glide pads and trackballs, may be new to you.
To adjust a GUI control knob via glide pad/trackball
Adjustments of controls, such as a control knob or fader, on a GUI screen are done via
the glide pads/trackballs in the input and primary navigation zones, respectively. Each
glide pad will only operate the GUI screen within its bay, whereas the left-hand
trackball in the output bay operates the mix bay GUI screen and the right-hand one
operates the output bay GUI screen. Operation of both glide pad and trackball is
basically the same as using a mouse on a PC, as illustrated in the following example.

adjustment
1 Move your finger on glide pad or trackball to move the GUI screen cursor until it is
positioned over the control knob you wish to adjust.
2 Using your other hand, press and hold down the select button (left-hand button) to
select the control knob under the cursor; cursor on GUI screen disappears to show
that control knob is selected.
3 Adjust the control knob by moving your finger again on the glide pad/trackball,
while still holding down the select button.
4 Release select button when you have achieved the required value.
Note:
On the glide pad, you can also select by quickly
double-tapping on the pad itself instead of using the select
button, which may be more convenient as you only need to
use one finger to complete the task.
