Redundant Mainstage rig - help
I'm building a redundant Mainstage rig for an MD playing a Nord Stage 4, trying to use as many of the pieces of gear we already own as possible.
The MD in question is keen on using his own USB buttons to trigger the changing of his Mainstage patches, as opposed to a button on the keyboard or a foot switch into the back of the Nord. Is there a way of splitting this USB button signal to both the primary and backup machines? In an ideal world, the MD should not have the physically do anything different to play on the primary or backup, so physically using a separate button would not be preferred.
If relevant (perhaps for some network-based solution), the two Macs will be side by side.
Is there a simpler solution that I'm missing? Or do i need to politely explain that the only way to make this work is to use a Nord button or ftsw into the piano
Thanks
