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. Marc __________________________________ Do you Yahoo!? Yahoo!
