In addition to the investment of our GMA3 Commandwing kit we have made another investment in MA hardware. This time we have chosen to invest in a Viz Key which allows us to use the maximum of parameters (250000) in a GrandMA3 session to be programmed from a Commandwing in a visualiser like WYSIWYG or Depence 3. As a bonus we can use the Viz Key to add an additional 512 parameters to the 4096 parameters of the Commandwing.
