NSPs do not add parameters to a gMA3 onPC system, but can be used in Art-Net mode if you have the parameters from gMA3 onPC hardware.
Thats what I was suspecting before moving any further. Currently my setup using L8 Pre-Vis along with MA2 ONpc on my desktop needs the MA1 NSP in-line to recognize L8 software. Was hoping I could just use the in place NSP to start learning/move forward with MA3 while at home and in my office. I do wish MA Lighting still allowed L8 (and some other previs softwares) to work along with MA2, and of course now MA3 ONpc, without having to purchase more externals.
Thanxs for the heads up Ryan. Much appreciated!
