Use the Ducker plug-in
1. In Logic Pro, insert Ducker into an aux channel strip.
2. Assign all channel strip outputs that are supposed to “duck” (dynamically lower the
volume of the mix) to a bus—the aux channel strip chosen in step 1.
3. In the Ducker plug-in window header, choose the bus that carries the ducking (vocal)
signal from the Side Chain pop-up menu.
Note: Unlike all other side chain-capable plug-ins, the Ducker side chain is mixed with
the output signal after passing through the plug-in. This ensures that the ducking side
chain signal—the voiceover—is heard at the output.
4. Adjust the Ducker parameters.
EQ
Logic Pro Legacy DJ EQ
DJ EQ combines high and low shelving filters, each with a fixed frequency, and one
parametric EQ. You can adjust the Frequency, Gain, and Q-Factor of the latter. The
DJ EQ allows the filter gain to be reduced by as much as −30 dB.
DJ EQ parameters
• High Shelf slider and field: Drag to set the amount of gain for the high shelving filter.
• Frequency slider and field: Drag to set the center frequency of the parametric EQ.
• Q-Factor slider and field: Drag to set the range (bandwidth) of the parametric EQ.
• Gain slider and field: Drag to set the amount of gain for the parametric EQ.
• Low Shelf slider and field: Drag to set the amount of gain for the low shelving filter.
