I upgraded my system on the recommendation of this mailing list, because of a kernel bug that prevents four channel output on my device in 10.04. I need four channels for a concert in a few months. So it's either upgrade or cancel the concert.

Fair enough. Ubuntu Studio next time?

In the meantime, maybe someone else could help me? I can understand if Paul is busy (who isn't?) but I'm either too worn out or not smart enough to figure out alsa all by myself.

Now I have this:

pcm.merge {
    type multi;
    slaves.a.pcm "hw:Pro,0";
    slaves.a.channels 2;
    slaves.b.pcm "hw:Pro,1";
    slaves.b.channels 2;
    bindings.0.slave a;
    bindings.0.channel 0;
    bindings.1.slave a;
    bindings.1.channel 1;
    bindings.2.slave b;
    bindings.2.channel 0;
    bindings.3.slave b;
    bindings.3.channel 1;
}

ctl.merge {
    type hw
    card 1
}

And I get:
