A control surface can't do any direct interaction with GMPI, setting
parameters or anything like that.  Somewhere, there will be some software
layer doing the communication to and from the hardware, either a driver or
a plugin or the host itself, but somewhere there will be software for the
control surface.

And thanks for the example, I wasn't thinking that the IDs would be
generated by the host.
