MIDI plug-ins
Use MIDI plug-ins in Logic Pro
MIDI plug-ins are inserted in software instrument channel strips and process or generate
MIDI data—played from a MIDI region or a MIDI keyboard—in real time. Included are
the Arpeggiator, Chord Trigger, and Modulator, along with plug-ins for transposition,
randomization and other processing. Scripter enables you to create your own MIDI
processing and generation scripts.
MIDI plug-ins are connected in series before the audio path of a software instrument
channel strip.
MIDI plug-ins have a MIDI input, the MIDI processor, and a MIDI output. The output signals
sent from MIDI plug-ins are standard MIDI events such as MIDI note or controller messages.
Insert one or more MIDI plug-ins
1. In Logic Pro, click the space between the EQ graphic and the Instrument slot of a
software instrument channel strip.
2. Choose the name of the MIDI plug-in you want to use from the MIDI plug-ins
pop-up menu.
The selected MIDI plug-in window opens, and a green label with the MIDI plug-in name
is shown in the channel strip.
3. To insert additional MIDI plug-ins, move the pointer over the top or bottom edge of the
inserted MIDI plug-in label in the channel strip, then click when you see a green line.
Note: The plug-in window does not open automatically for MIDI plug-ins inserted in this
way. Click the label to open the plug-in window.
Change the order of MIDI plug-ins
• In Logic Pro, drag the label of the MIDI plug-in that you want to move over the label of
the target MIDI plug-in.
• If the target MIDI plug-in is in the top slot: It is moved down the list.
• If the target MIDI plug-in is in the bottom slot: It is moved up the list.
• If the target MIDI plug-in is in a middle slot: The positions of the two plug-ins
are swapped.
