the more graphic gimmickry, the less professional. You'll see more
graphic gimmickry on cheap consumer hifi gear, than on better class
consumer hifi gear, let alone professional gear. The same is true for
software. For what purpose do you need a graphical overview of
all connections during a production?

Real gear as well as virtual gear is connected one time, there's no
need to have a picture of all connections. Select the MIDI channel of
the wanted MIDI instrument, name the audio and bus faders, that's it.
On a real mixing console you would use a permanent maker to write on
tape.

Keep it simple and straightforward!
