Here's the situation on real-time kernels.

For Lucid:

There is a real-time kernel in the official Ubuntu repositiories, the
package is called linux-rt.  It is not installed automatically by
Ubuntu Studio, because it is based off an older version of the vanilla
Ubuntu kernel.  It still works well, though.  A lot of people on this
list (perhaps most, and including myself) use the kernels in Alessio
Bogani's PPA, information for which can be found here:

https://launchpad.net/~abogani/+archive/ppa

For Maverick:

There are no official real-time kernels available for Maverick.  Some
people seem to have successfully used Bogani's Natty kernels with
Maverick, so that is perhaps an option.  There are other PPAs
available, as well, and you could build your own kernel, too.

For Natty:

At this point, the kernels available in Bogani's PPA are the wants you
will want to use for Natty.  There will no longer be any real-time
kernels in any official repositories, for various reasons, including
lack of enough support to maintain one.  It is a goal to have one of
the low latency kerenls that Bogani has developed be put into an
official repo for Natty, but I have not recently heard about how that
is going.

There are other issues with real-time in Maverick and Natty that have
recently come to light.  This page will fill you in:

I'm not positive about this, but I think Bogani's kernels have been
updated to solve this problem.

By the way, I'm glad to hear you've got your interface working.
