Greetings:
I'm doing some research for an article about Linux MIDI support. In my
text I briefly describe the evolution of the MIDI specification since
its adoption, mentioning things like MIDI Time Code, MMC, the sample
dump standard, and the standard MIDI file. However, one item has me a
bit mystified. I'm unable to ascertain whether multi-port interfaces are
in fact described and supported by the spec. I checked the MMA docs
on-line, and I also have the Sciacciaferro/De Furia MIDI Programmers
Handbook, but nowhere do those sources indicate explicit support for
multi-port hardware. Are multi-port MIDI interfaces vendor-specific
solutions or is there actually an extension to the MIDI spec somewhere
that I'm just missing ? TIA!
Muliport-interfaces were included in the initial discussions on the MIDI
standard and referred to as "star systems":

It was thought that a single interface would be good enough for stage
and budget systems and that professional recording studios could
overcome bandwith limitations by using one port for each synth-module
attached.
No specifics regarding naming nor discovery were mentioned. I suppose
Roland, Sequential and Yamaha intended to build and sell those
sequencers all by themselves ...
The place to look for a universal standard for multiple midi-devices
would be in the USB specification. And it even appears like some vendors
are (finally!) starting to follow suit:
