Hi everyone, I’m a little new to the Ardour forum.
I’m exactly in the same situation as described in this post. Unfortunately I couldn’t reopen the topic since the latest reply was already more than 3 months old.
But here I here I am more than 3 months later and the problem is still the same. I’m disposed to run any kind of tests to make this Novation Launchkey 49 keyboard work.
I’m running Ubuntu Studio 24.04.3 LTS but I updated Ardour to the latest version 8.12.0.
The linked post described the problem as being in the kernel ALSA driver.
I have not heard whether the patch which Paul proposed to the kernel driver was accepted or not in newer kernels (which could be backported to stable kernel bugfixes).
The patch was accepted and I think has been in all kernels since 6.12 or thereabouts. Certainly my current Debian buster system has the fix direct from Debian.
It’s not an Ardour problem, as in: there is nothing the Ardour authors can do because It’s a kernel problem and (AFAIK) cannot be fixed or worked around in user software.
I was sorry, but I sent mine back and bought a different controller.
At this point, you probably cannot return yours, and it should be supported in the near future; perhaps in the next kernel update.
Thanks @paul for the heads up about the kernel update. I’ll go check if my Ubuntu Studio relies on kernel 6.12 or higher. If not, I’ll try to reinstall Ardour on another distribution which does.
I’ve had another idea that might be a viable bypass for the time being.
Up until now, I’ve been connecting the Launchkey using its USB-C port. But it also has a MIDI port which I could use through my Scarlett. And then, I could check if the MIDI devices announced by the sound card are named differently by my current kernel.
