[linux-audio-dev] a question re: the MIDI spec

  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!

Best regards,
