Maybe "81:0"?

Now I get serious. Fluidsynth creates a new port, when started like this:

$ fluidsynth  -m alsa_seq   /usr/lib/awe/sfbank/8mbgmsfx.sf2

You see it here:

$ aconnect -lo
client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel]
    0 'M Audio Audiophile 24/96 MPU-401'
[...]
client 128: 'FLUID Synth (10195)' [type=user]
    0 'Synth input port (10195)'

Then you can aconnect this port to the one you like:

$ aconnect 64:0 128:0
$ aconnect -lo
client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel]
    0 'M Audio Audiophile 24/96 MPU-401'
        Connecting To: 128:0
[...]
client 128: 'FLUID Synth (10195)' [type=user]
    0 'Synth input port (10195)'
        Connected From: 64:0

Now I can play fluid from my keyboard.

ciao
