i am using two pairs of monitors and two pairs of headphones in my studio. They are all connected to different hardware outputs of my audio card. I am using the control software for my audio card in order to switch between output channels, These channels are not visible to the PC or Reference 4.
My request would be to allow for sending a signal to Reference 4 for selecting a calibration profile. This could by a command line option or a MIDI message for example. I can remote control the channel selection of my audio card and this feature would allow my to switch to a hardware output and select the related calibration profile at the same time. Currently i always have to remember to select the right profile after switching to a different output device.
