• Trigger mode: Determines how the polyphony of the instrument is handled when
the number of notes played exceeds the number of available voices. Trigger mode
also allows you to assign legato mode. Essentially, this control changes the way the
synthesizer responds to your playing technique. It is invaluable when you are emulating
monophonic instruments, such as flutes, clarinets, and trumpets. When you use the
trigger mode control and assign a last note priority, the played note is cut off by playing
another note.
• Last note priority: When new notes are triggered while all voices are playing, the
synthesizer frees up polyphony (voices) by ending the notes played earliest. This is
the default trigger mode of Logic Pro synthesizers when in a monophonic mode.
• First note priority: Notes played earlier are not stopped. In this mode you need to
stop playing notes in order to play a new one after you have reached the limit of the
polyphony (voices) of the instrument.
Note: The trigger mode parameter can also allow you to set priorities for lower- or higher-
pitched notes when playing monophonically (one voice at a time) in some synthesizers,
such as Alchemy.
There are many other global controls found on different synthesizer models that have an
impact on your overall sound.
Other synthesis methods
Other synthesis methods overview
There are many ways to create sounds, using different technologies and approaches to
synthesis. This section covers all main methods, with reference to Logic Pro instruments
where applicable.
Many of the methods described incorporate at least some elements of the subtractive
synthesis design. See How subtractive synthesizers work.
• Sample-based synthesis
• Frequency modulation (FM) synthesis
• Component modeling synthesis
• Wavetable, Vector, and LA synthesis
• Additive synthesis
• Spectral synthesis
• Resynthesis
• Phase distortion synthesis
• Granular synthesis
