Comment 45 for bug 27833

I'am affraid it is so.
But in the previous post I've sayed to look at the qjack control tab marked as MIDI, instead you should look also at the tab marked ALSA and see after clicking on 'refresh' button if it shows some MIDI device appart from 'Midi Through'. If the answer is yes probably it is the Oxygen device, even if it is namend with an other name. In that case probably it will be recognaized and work with usual MIDI software such as Rosegarden and soft synths like ZynAddSubFX.

If it is not recognized in any way on qjack control, then the only hope is to wait for newer versions of ALSA that will incorporate generic 'class-compliant' driver support for the Oxygen 8 v.2. Since it is a popular brand there is hope that this could happen.

That is the usual way that goes with Linux. The most recent hardware --and the new version 2 of that particular keyboard it is a rather new-- have to wait some time untill is fully supported.

Of course there is a workaround to make the keyboard work in the meanwhile: since it has a standard MIDI out port you could use a generic USB MIDI interface of that sort that is usually found on eBay and the like and to interface the Oxygen with the computer through that.
