Description

vst3presetsave saves a plugin preset to a file. The preset file stores the identifier of the instrument or effect, the identifiers, names, and values of all the parameters in the program, and possibly other information such as a program list.

Syntax

vst3presetsave i_handle, S_preset_filepath

Arguments

i_handle: the handle that identifies the plugin, obtained from vst3init.
S_preset_filepath: the full pathname of the preset file. Remember to use '/' instead of '\' as the path separator.

Output
