Hi,
GP inputs are triggered by a state change, either by transitioning from open to closed, or vice versa. Same goes for the footswitch inputs, as they're essentially GP inputs with a different connector.
It's definitely possible using GPIO to have a single press of a momentary switch recall a specific snapshot, or trigger the next (or previous) snapshot. So maybe there's a simple solution here.
For example, to recall snapshot 1, create an Event as follows:
- Trigger = Input 1 (GPI Input 1), Closed
- Action = Recall Snapshot 001 <snapshot name>
Similarly, to recall snapshot two using a second switch wired to GPI 2 would be:
For example, to recall snapshot 1, you would create an Event as follows:
- Trigger = Input 2 (GPI Input 2), Closed
- Action = Recall Snapshot 002 <snapshot name>
Note that this assumes the switches are momentary, and
normally open (so pushing the switch closes the contact and completes the circuit). If the switch is
normally closed, simply change the triggers shown in the above examples from "closed" to "open".
It's also possible to do GO and BACK buttons for theatre this way, again requiring only a single press.
If you provide more info on how the events are set up (triggers, actions) we can work this further.
