Interaction of
Presets and GPIs
If you use a GPI input trigger to recall a preset, the recall changes the GPI IN Response
setting to whatever GPI IN Response setting the preset contains. This feature offers
both the power of serial recalls and the possibility of triggering a recall that changes
GPI IN Response to something unintended, as the following examples explain.
Example of a Serial Recall
The advantage of using GPI IN Response with presets is that you can trigger a series
or even a looping series of preset recalls. For example, suppose GPI IN 1 Response in
Preset 1 is set to Preset 2, and GPI IN Response in Preset 2 is set to Preset 1. Triggering
the GPI will toggle between the two presets.
Example of an Unintended Recall
Suppose you trigger GPI IN 1 while the current GPI IN 1 Response parameter is set to
Preset 1. This recalls Preset 1 as expected. However, suppose Preset 1 contains a
stored GPI IN 1 Response setting of No Action. If you trigger GPI IN 1 later, expecting
to recall Preset 1 again, the FS2 instead performs No Action. To prevent unexpected
changes in the GPI IN Response parameters, set these parameters as desired before
storing presets; in the example, set GPI IN 1 to Preset 1 before you store Preset 1.
