I've installed LMMS 1.2.1 on Lubuntu 20.04. I've plugged in the MidiPlus AKM320 keyboard. I start LMMS. I go to Edit -> Settings -> Midi Settings and I don't see the keyboard listed.

Linux sees the keyboard with the lsusb command. The 'aconnect' command sees the keyboard. I have it working with ZynAddSubFX (using the 'aconnect' command to link to two).

I've watched a few LMMS tutorials on Youtube and they show LMMS just discovering the keyboard from start up. Is there something additional that I need to do?

TIA,

Tim

Did you get LMMS from an (L)ubuntu repository ?

If so, first thing to try is this LMMS version:

https://lmms.io/download#linux

1.2.2

Make this file executable then double click the file to start LMMS.

GPS is correct! Get the AppImage. But else provided that you have done exactly what you wrote (fist KB, then load LMMS, then look for KB ) your MIDI-KB should be detected.

I have downloaded the AppImage 1.2.2 version. I made sure that it executes. I plug in the keyboard. Confirm that it is seen:

$ lsusb | grep Midi
Bus 001 Device 016: ID 1acc:3c01 Midiplus Co, Ltd. AKM320

$ aconnect -lio | grep AKM
client 20: 'AKM320' [type=kernel,card=1]
0 'AKM320 MIDI 1

I then start LMMS, go into Edit -> Settings -> Midi keyboard and it is not on the drop down list. All I see in the list is:
-- ALSA-Raw Midi
-- ALSA Sequencer
-- Dummy
-- Jack Midi
-- OSS Raw Midi

Are you looking in the right spot.

Lets take a look at the triple OS.

Click the midi tab, and see if your keyboard is there.


https://docs.lmms.io/user-manual/4-prod ... using-midi

Opening the Midi Tab on the Triple OS only give a check/tick box for Input and Output. I check/tick the Input box and nothing happens. I've even gone back to the Edit->Settings->Midi tab and the keyboard is not showing up.

I looked for the Instrument Settings window and I could not find it.

Is there a log file that LMMS generates as it starts up that I could check (even if I'm using the 1.2.1 version)?

I started the appimage version in a terminal. Here is what was shown in the terminal on startup:

Carla does not appear to be installed. That's OK, please ignore any related library errors.
Jack appears to be installed on this system, so we'll use it.
Notice: could not set realtime priority.

/dev/midi1 does exist. Hope this helps in understanding the issue.

I am lost on why it does not work.

Maybe people here have an idea.

Idk if this would help, but have you tried booting the pc with the MIDI-keyboard ON
Then perhaps the MIDI-keyboard would be detected as the boot takes place.
Its a drag when there are HW issues with LINUX-installations, because there could be any issue with 'anything'. Thats the LINUX-catch-28. There is no standard..

On top of that you could have a flawed cable.
Midi cables are very sensitive. They break easily.
Can you test the cable with some other software, perhaps a demo DAW or similar

Any update?
