[LAU] MIDI hardware with Linux

[Kevin Cosgrove]

Could someone point me to some reference material to get MIDI 
hardware up and running on my Linux system?  I knew how to do this 
just fine about 3 rev's of Ardour and 1 major rev of the kernel ago.
Unfortunately, all the documentation I'm finding is 7-10 years old.

I'm trying to figure out how to interconnect the *MIDI* of the following:

- M-Audio Delta 1010 hardware MIDI ports
- Mackie Control Universal hardware MIDI ports
- Alesis QS8 hardware synth
- a2jmidid software MIDI interface
- Ardour jack-MIDI ports

What can you folks advise?

Thanks...
