alsa-project/alsa-lib issue #442 was opened from Thrilled-Oaf:
Greetings~.
I'm on Slackware, which is a pretty languid, laid back distro... so I have to admit that I don't know when this happened... But I recently updated it, cause I bought a new midi keyboard, a launchkey mk4, and it should have a 'DAW' port, both on its USB connection and the classic pinned midi cable thing.
But instead, aconnect -i and all that just gives me ``` client 24: 'Launchkey MK4 61' [type=kernel,card=2] 0 'Launchkey MK4 61 Launchkey MK4 ' 1 'Launchkey MK4 61 Launchkey MK4 ' ```
I actually use JACK audio on top of alsa but even without jack, this still occurs. I can sort of pretty print this for JACK but it would be best to have this working properly at the very base... cause if I disable all alsa seq/raw support from JACK, then DAWs like ardour won't even see any midi ports anymore.
I also tried being 'clever' and loading `snd-seq-dummy` and setting up some routing that way... didn't work. Then I actually edited the source file for the dummy device to specifically give me a properly named DAW port if the index of the dummy port was like, 3 or something. And while the naming worked, it was ultimately ...not able to help out with this issue.
What is basically assumed by many clients, including the configuration utility `components` for the keyboard is that it has a distinguishable second midi port with a DAW suffix, thus...this is what `aconnect -i` should ideally show.
``` client 24: 'Launchkey MK4 61' [type=kernel,card=2] 0 'Launchkey MK4 61 Launchkey MK4 ' 1 'Launchkey MK4 61 Launchkey MK4 DAW' ```
I think I read an email somewhere that alsa might be running into a name length limit, but ...perhaps there's a way to configure this? If not through a configuration file, then maybe somewhere in the source itself...?
I am not shy about that but I would need directions...100% lol.
I also looked up other issues here and some talk about portaudio and mixxx and stuff but this is definitely a system wide issue for me. And so sad too, it's a text descriptor... a text label of all things... bringing the mighty ALSA to its knees. A measly, peasly, text label for a little bittle MIDI port...
I tried udev too but ...that was utterly fruitless due to my lack of knowledge/skill... but this all should signal that I'm willing to put in some work, too. I just don't know what to do anymore. maybe .asoundrc but all the examples are about PCM and my PCM cards work fine, it's just this MIDI ambiguity thing...
