The user interface mainly consists of dials and buttons. The numeric values under the dials
can be clicked to enter a numeric value. Some dials feature context menus accessible via
right-click. See below.

Pro Tip: You can use the One Shot mode to effectively act as a tremolo effect if you set the
threshold to a very low value, thus always re-triggering the Ducker after each Release period.

.?@A'@B
,-!"-C"9 @@/1@1
Refer to your D W’s manual for information on how to make a plug-in receive MIDI data.
In Logic Pro X, to use MIDI TRIGGER, create a Software Instrument track and insert a Bob
Perry Ducker Pro 2 instance as an instrument (not as an insert FX!). Then use Logic’s Side
Chain menu to “grab” your audio signal from your audio track. You will then want to mute your
audio track’s output and only have the Software Instrument track output your signal.

If you want to use Ducker Pro 2 for M/S ducking without sidechaining, just skip points 2 and
2a and adjust the M/S functions as required.

Note: If you have a Stereo track with mixed music you can do de-essing but it's a little bit less
straight-forward. Try the M/S feature:
Usually the Vocals are in the center (Mid) of the mix. Switch the M/S modes of the Main and
ux to “MID”. Now you only process the center of the mix without touching the side signal.
