What Can’t Be Processed on a Node
The Node buttons are available for all audio and software instrument tracks. There are,
however, some exceptions:
 EXS instruments: These are always calculated on the host. The reason for this is the
potentially demanding transfer of samples via the network, resulting in a slowdown
of audio processing over the network. The sample library needs to be present on the
host computer itself.
 Multi output instruments such as Ultrabeat: Further to this, Ultrabeat also has a similar
problem to the EXS24 with sample-based kits.
 Audio Unit software instruments: When an Audio Unit software instrument track is
selected, the Node button is automatically turned off.
The Logic Pro Node application can process Audio Unit effects.
It is possible, however, that some Audio Unit effects may not support the Node
functionality of Logic Pro. You can disable the Node processing for incompatible Audio
Unit effects in the Audio Units Manager.
It is not possible to calculate input, output, bus, or aux channels on a Node.
