2 Instruments and Effects
This chapter explains the difference between effect and
instrument plug-ins.
Instrument plug-ins respond to MIDI note messages, effect plug-ins do not. Therefore
instrument plug-ins can only be inserted into special Audio Objects, called Audio
Instruments.
Effect Plug-ins
Logic’s effects can be installed into all insert slots of all Audio Object types (See
“Inserting and Deleting Plug-ins” on page 13.). This allows processing of all audio and
instrument signals.
There are two ways of sending audio to effects: via an insert, or via a bus (also known
as an “aux send”).
Insert Effects
With insert effects, all of the signal is processed. This means that 100% of the signal
flows through the effect. This is suitable for equalizers or dynamic effects. This also
typically applies to pan knobs and faders.
If you have enough processing capacity, you can use up to 15 insert effects per audio
object. An extra blank insert is created, as soon as all the currently displayed inserts are
used, up to the maximum allowed.
Bus Effects
When you use bus effects, a controlled amount of the signal is sent to the effect. Buses
are typically used for effects that you want to apply to several signals at the same time.
