Thanks to both of you - an interesting device but with a rather perverse operation.

I would like to add 2 vertical buttons for the 2 dials on the right side (each consisting of an upper and lower half for the 2 dial directions) that can be used with the mouse.
Of course I can add an extra port for these 4 'fake' buttons in the driver and layout (mapped to the 4 cursor keys), but I have no idea how to 'connect' them to the existing port "IN.0" so that they work exactly like the cursor keys in your version - I've never seen such a strange port definition in any of your drivers so far.
Is this possible, and if yes: how?

Regards,
Franz
