there is a way over ssh (there is always a way over ssh )
in > 1.7, there is a single port where all midi devices connect to (midi-aggregator), connecting stuff there will send stuff to the MIDI in port you see in the web interface.
so some jack_lsp -c and jack_connect combination should do it.
There is no other “more official” way to do this right now.
Obviously, the plugin needs to output a MIDI CC in order for this to work
Maybe it’s better to describe the practical idea instead. I’d like to be able to determine via an ssh connection if a particular control on a given plugin is on or off, and ideally, I’d like to identify it using the CC message ID associated to it.
But you’re right, it might not be the right thread.
