[linux-audio-user] multiple MIDI interfaces

Soon i'll have to connect 3 MIDI devices to a Linux system (and also
send MIDI between the devices themselves, not only device<-->computer):
two hardware synths (keyboards) and an effects box. Possibly another
device later, but we'll see.
What MIDI box do you recommend in this case?
I'm looking at M-Audio USB MIDISPORT 4x4 which seems to be quite ok:


Anyone using it? Can you route the MIDI signal in arbitrary ways? Can
you route one input to all outputs, or do other similar things? What's
the software that you use to control it?
Does it work with your sequencer?
How well does it work with ALSA?

If you have a sound card (or maybe two soundcards) on your system, can
you use its MIDI interfaces in addition to the 4x4? Can you do arbitrary
MIDI routing in that case?

On the ALSA website, next to the 4x4 it says "Firmware driver coming
soon" - what does that mean? Is it not supported yet?

If 4x4 doesn't work under Linux, can you recommend a product similar in
features and price?
