MIDI Does not work on Linux / Ubuntu

• Nov 30, 2019 - 10:48

Hi,

I am running Musescore 3.2.3 on Ubuntu 19.

I have an AKAI LPK 25 keyboard. When I use Bitwig, all I have to do is plug it in and it works (zero configuration).

I have been trying for a week to get this to work with Musescore and it doesn't work.

In I/O settings I have tried:
- ALSA Audio (default) - Does not work. MIDI DIN symbol disabled light blue
- PortAudio -Not a single option appears in drop down menus, Musescore crashes if press okay
- PulseAudio - The MIDI DIN Symbol can be enabled / disabled but no input is seen
- Jack Audio Server - The MIDI DIN Symbol can be enabled /disabled but no input is seen
- Jack Audio Server (and disable "use Jack MIDI") - Musescore crashes

This, in addition to the advice "plug in your midi keyboard before starting Musescore", makes a bad user experience.

As I said, on Bitwig, I plug it in and it just works. There are no functioning options for me on Musescore.
Additionally, every other MIDI input musical software I have used has an indicator (visual) when MIDI notes are incoming / outgoing. This is because a MIDI note is not an audio signal so it can be helpful to see it.

Also, as a user, I don't really care what audio server I am using - I just want my MIDI keybaord to work. How can I troubleshoot this?

Others use it, so it can work. Unfortunately I don't really have any insight into the specifics of Linux device drivers and what not.

In the configuration(s) where you have a functioning MIDI icon - you say it doesn't work, but can you be more specific? What exactly are you trying - entering notes in step-time note input mode, and nothing appears? Or something else?

It's really just the pulseaudio setting that allows the MIDI icon to be enabled at all.
And yes, I enter note input mode and then press a key on my midi keyboard but nothing at all happens.

This is one reason why having a MIDI IN Indicator (like DAWs) would be a good feature to have.

yeah, i'm having the same issue over here, except it's my playback that won't work. I've heard that portaudio -> built-in output works well, but I have the same issue with the drop-down menus
