Sounds like what you want in the end is a visual graphic of the current volume level that changes as you change the volume. This is done easily enough with something like Crestron because there is 2-way comunication between the processor and touchpannel but as I understand from everything I've read about the 9600, the 2-way that is comming to the 9600 is only for music server type applications. I could be wrong, but since it won't even have flags or conditional logic, don't hold your breath.
