Respectfully, this doesn't make sense to me. All MIDI devices that you
can connect to these MIDI Through in and out ports could be connected
directly. The keyboard, which might be transmitting on channel 3 of a
certain physical MIDI port, could be connected to the soft synth
directly. What value does using the MIDI Through provide?

Further, since MIDI handles only 16 channels having a single MIDI
Through port would seem to limit you to 16 MIDI channels.

I already do MIDI Through on my system. I run two MIDI Outs from Pro
Tools to two MIDI Ins on my Linux box. I hook MIDI In to MIDI out on
both channels on my Linux box using aconnect commands at boot time and
then run two MIDI outs from Linux to a 3rd machine running GigaStudio.
I typically run 32 MIDI channels of data doing orchestral stuff. This
allows Pro Tools to drive both the Linux box and the GigaStudio box
all the time.

This new MIDI Through wouldn't allow me to do that since it's not
associated with any specific physical interface. (Unless it's
implemented incorrectly.)

I still don't get it.
