Preset Names
When presets are stored, the preset name may be customized to any arbitrary
string of up to 256 bytes in length. When naming presets, keep in mind the
preset name is used in the command syntax to invoke the execution of the pre-
set. It is recommended that a preset name be descriptive to aid in selecting
presets for execution from within SoundStructure Studio. As will be described
later in this chapter, presets are executed with the run command with the
preset name as an argument.
Number Of Presets
The number of presets is limited only by the amount of available non-volatile
memory in the SoundStructure system. For single device installations, it is esti-
mated that more than 100 full presets may be stored in the device.
Saving Presets
After the system has been designed with SoundStructure Studio, there will be
a default full preset called “Power-On” and it will be assigned to be the
power-on preset. If any changes are made to virtual channel parameters or
matrix cross points are adjusted, the updated settings should be saved in the
“Power-On” preset by selecting the Save Selected preset as shown in the fol-
lowing figure.
When a preset is saved, all the audio settings of the device are compared to
their factory default settings, and only the settings that differ from the default
settings are stored in the preset. By comparing presets to a default set of val-
ues, the size of the presets are reduced which allows more presets to be stored
in the device.
Full presets store the differences from the default settings. If a parameter isn’t
shown in a full preset, it is because that value of that parameter is the same as the
default value.
