I click any button save my HISE project and re-compile.

The UI is set to the state I left it in (with the button I pressed == ON). So all good.

Now I use either a keyswitch or a CC number to change the articulation....

The buttons change as they should, the articulations load as they should, so all good still....

I save my HISE project, and recompile......

The buttons jump back to the last state of a mouse-clicked button....

What am I forgetting to do?
