JACK does not "grab" anything except *raw* MIDI ports and even then only if -Xraw is used, which is a bad idea to begin with.

Is there any way to do this kind of raw Alsa access with jackd going?

You might be able to use the vir-midi module for this. I looked into this
to help someone get JACK MIDI into Praxis. Should work for output too.

Bit more about what I did here -
http://code.google.com/p/praxis/issues/detail?id=31

I checked into this, and unless I'm misunderstanding what the module does, it doesn't look like it will help.  It seems to provide a virtual port for OSS apps to be able to access the Alsa sequencer ports.  The problem is amidi is already a native Alsa program, but it can't access the hardware ports because Jack has already grabbed them.  It's not an OSS versus Alsa issue, but just that the device is exclusively in use.

It almost seems like what we need is some kind of Jack-aware amidi command...
