Storing a value seems to be a problem...
I didnt find a way to do it with existing nodes and i created a extension with a memory node.




if you set it to 0 it gives the IN values to the OUT if you set it to 1 it stores the last value and gives this to out...

BUT: if you add a second one it doesnt work anymore...
Somehow both react like one.

Perhaps Karsten finds a solution...
