Default M-Audio Ozone Academic patch

Greetings,

Some of you may remember my sometime posts about attempting to get the M-Audio Ozone Academic MIDI keyboard/audio interface to work in Ubuntu Studio, or any other distro, for that matter.* Some folks in my local LUG discovered that a kernel patch had been written to allow the MIDI port to be recognized, and I have spent the last month unsuccessfully trying to boot the patched kernel.* Someone at the January LUG meeting patched the kernel on his Slackware laptop, and had TiMidity playing from my keyboard, but I have not had this kind of success.


Here is a link to something about this patch:



http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2ea547dcdd4216370f00dd65a18ee5a 0271646a0




It may be that this is scheduled to become part of the general kernel; I don't know how those decisions get made.* Seeing "torvalds" in that URL makes me wonder if* it's a done deal, and that eventually it will trickle down to Ubuntu.


If this patch is not destined to become part of the Linux kernel, I would like to know the how to best lobby the Ubuntu Studio devs to include this patch in a future version of U/S.* These keyboards are likely to become available on the used market, as they are part of a bundle that Digidesign is discontinuing.* People who want to get started in Linux audio could benefit from kernel support for a basic do-it-all USB device that may become common and inexpensive.


In any case, it would be a good idea for me to learn to apply this patch to U/S, and I would welcome responses from Ubuntu Studio users who have successfully applied kernel patches.* Where are the best how-tos and tutorials for this?


Thanks,

Paul in Seatte

Default M-Audio Ozone Academic patch

I've been away from the list for a while, so I haven't seen any of your posts, but I'll see if I have
the old threads archived. I'm surprised though, the M-audio ozone "just worked" for me, I'm using 7.10.

What kind of problems were you having? I just bought a generic 1x midi-usb interface on Ebay. Is there
an issue with midi communication over the USB port?

Hi, Adam,

Yes, most Ozone keyboards work better than the sub-version designated "Academic" on the front panel. That's why the patch was written especially for it.


There is a six-page thread in Ubuntu Forums about trying to get the M-Audio Ozone to work; most people have not had it "just work' with Ubuntu.* Page 5 and 6* detail how the extensive tweaks did not work with my particular version.* Then I took the Ozone and my computer to the January GSLUG (Greater Seattle LUG) meeting, and two guys discovered the patch online.* It was the FIRST TIME I ever saw any MIDI working with it; the guy was using aconnect with TiMIdity in Slackware.* He did not have JACK installed.


These guys then helped me compile and install a patched kernel, but I have not been able to get it to boot. The original kernel works fine, and I use the Ozone as the default sound card.* Everything will play audio through it except Rosegarden, but MIDI is not recognized.


For fun, here's a link to that Ubuntu Forums thread:

I am posting as Aurora.


Cheers,

Paul
