Trigger

A trigger in Box Of Stops is an external control - probably easier to reach than the touch screen.

Any Stop, Coupler or Combination can be assigned one or more triggers, which can be used to toggle that control. Each trigger could be:

• A program change (instrument) button on the controlling keyboard
• A pedal control (e.g. sustain or soft pedal)
• A spare note, outside the normal organ playing range on your keyboard
• Any external Midi device, e.g. a foot controller (typically designed for guitarists)
• A Gpio button attached to the Raspberry Pi

Adding a trigger to a control

To add a trigger to a control, first tap the spanner icon to start Configuration mode, then the pencil icon next to the name of the relevant stop, coupler or combination.

Next click the plus icon at the end of the list of current triggers. The screen will then wait for you to press the new trigger, to detect the new input.

Once you OK the screen, the new trigger will be ready to try.

Reassigning a trigger

Note that when adding a trigger to a control, if that trigger was already assigned to another control, you will be alerted to this. Click OK to continue and steal the trigger, or Cancel to try again.

Triggers belong to a Registration

Note that triggers are part of the saved Registration that is created in Configuration mode. If you create multiple registrations, these can have different trigger assignments.
