For example, A.Filter/M.Filter, Phaser/Flanger, etc.

An FX button will light up red to let you know that it is active. Having the
FX button engaged on a channel will allow you to cue the effects on that channel, but
will not send the effect to the master output unless you press the
FX ENGAGE button (it will blink blue to let you know it is active). (Figure 4.6)
Now let’s look at the effects!
To send an effect to a channel, the CHANNEL FX button must be pressed on that channel.
