"External Source Controls"

Has anyone used “External Source Controls” yet?

Would it mean that one could for example have both a MicroRendu and a Raspberry Pi on the same zone, with the Pi sending over RS232 switching commands to the receiving DAC?

Just curious…

Sure, something like that. I’ve been meaning to implement one for the Marantz AVR that we use with the TV so we can have convenience switching + standby for Roon.

That sounds like exactly what I’ve been looking for. How do I get started setting this up?

Never mind, I found it. It requires an API extension, which I don’t have the programming knowledge to create. If you create a Marantz AVR extension, could you make a Denon one while you are at it? Thanks!
