So, I’ve got a scenario where a CDM32 or 48 would be located in one spot and I need a small expander for a handful of extra inputs and outputs at another location. Control would be entirely via laptop / tablet so a surface is not an option. The AR84 would be awesome for this expansion but it appears that it is not compatible with any of the in built expansion options in the dlive mix brain box. Are there any other options that I should look at for this?
