Matrix: Two sources triggering the same matrix control

Matrix: Two sources triggering the same matrix control

By Administrator

Problem:A panel key and a matrix GPI trigger the same control. The control triggers a route and a GPO.
The GPI is activated and the route and GPO are triggered. 
The panel key is pressed. No change, the route and GPO are still made.
The panel key is unlatched. The route is broken and the GPO released.
NB: This issue is fixed in later versions after EHX v8.5

Solution:A workaround for this is to use two extra controls and a logical OR gate.
Make a control for the panel key.
Make a control for the GPI.
Use Logic Maestro to OR the two new controls and output to the original control.
Attached is the necessary logic.
