How to Use the Arpeggiator and MIDI FX in Logic Pro
Master the Arpeggiator and MIDI FX in Logic Pro. Learn to create complex rhythmic patterns and melodic sequences from simple held chords.
This guide demonstrates how to use MIDI FX plugins to manipulate incoming MIDI data before it hits your instrument. You will specifically learn how to set up the Arpeggiator to turn chords into rhythmic patterns.
Follow these steps
Locate the MIDI FX slot
Create a Software Instrument track and click the 'MIDI FX' slot located just above the 'Instrument' slot in the Inspector.
Load the Arpeggiator
Select 'Arpeggiator' from the menu to open the plugin interface.
Choose a sequence direction
Select a pattern in the 'Note Order' section, such as Up, Down, or Random, to change how the notes sequence.
Set the rhythmic speed
Adjust the 'Rate' knob (e.g., 1/8 or 1/16) to sync the speed of the notes to your project tempo.
Adjust the octave range balance
Use the 'Octave Range' control to determine how many octaves the pattern will travel through.
Common mistakes
- Placing the Arpeggiator after an instrument plugin; MIDI FX must always be placed in the specific MIDI FX slot.
- Choosing a 'Rate' that is too fast (like 1/64) for the tempo, resulting in a chaotic sound.
