FUNCTION
The labelling underneath the keys denotes their function when in Q-CHANNEL 'mode' and you have 'hands-on'
control to bypass the EQ and to switch FX/AUX 1-4 as pre- or post-fade.
Of course, for the Q-CHANNEL 'mode' to be applicable, you must select a channel for editing (i.e. you should press
a channel's SELECT key).
