= Target "FX: Browse presets" Steps through FX presets. This target is suited for use with xref:further-concepts/mapping.adoc#knob[knobs], xref:further-concepts/mapping.adoc#rotary-endless-encoder[encoders] and xref:user-interface/mapping-panel/glue-section.adoc#incremental-button[] because it allows you to step through the complete preset list. The minimum value always represents _No preset_ whereas the maximum value always represents the last available preset. It's _not_ suited for activating a particular preset (e.g. by setting xref:user-interface/mapping-panel/glue-section.adoc#target-min-max[] to the same value), because the preset list of an FX is usually not constant. As soon as you modify the preset list, this value will might suddenly point to a completely different preset. Even worse, the actual preset might have been deleted. If you want to activate a particular preset, please use the xref:targets/fx/load-snapshot.adoc[] instead.
