As aucat was simplified, base system lost the ability to move midi
data from one port to another; for instance to connect a midi
keyboard to a synth.
The diff below adds the midicat utility which I used last few
months to test/debug my midi setup and to connect my keyboard to a
my synth. Example:
midicat -i rmidi/0 -o rmidi/1
I could provide a diff to add this to the ports tree, if it's a
more appropriate place for it.
Thoughts? Other ideas? OKs?
