I have an X-Touch Extender and control it using a home made program sending midi sysEx messages. I am able to control the top text, button text, colors and inverted colors of each display. But is it possible to display custom message by setting individual pixels on/off? Or display custom images on the displays in any way? It would be nice to be able to control this to be able to use the X-Touch for more different types of operation. At the moment I'm using it to control lighting and would like to be able to display gobos on the display.
