I can get the input source to change if I send
MLServeCmd.MLDeviceManager|4~ZoneSource~1~VCR1 instead of
MLServeCmd.MLDeviceManager|4~ZoneSource~1~VCR-1 as it says in the documentation.
but still can't get:
MLServeCmd.MLDeviceManager|4~ZoneSource~1~CDR/TAPE to work from a mainlobby button, it works from within the plugin controller.
I'm also not sure about having the volume in db, while it is more linear it means the sliders don't work as the value runs between a negative and positive range, (-80 to +18 )
There are lots more commands supported, I am already using them one way via the TCP plugin. Perhaps some are not available on the 4806, but they certainly work on my 4306. The documentation on the 4306 can be found here:
