Qjackctl connect window - ALSA tab missing?

[schevening]

Hi Everyone,

Total newbie here, trying to set up my MIDI keyboard with Qsynth for the first time

I was following this tutorial: https://sndrtj.eu/2019/10/19/Using-a-US ... on-Ubuntu/, however, when I get to the "connect" step, my Qjackctl connect window only has Audio and MIDI tabs, but no ALSA tab (

Could anyone help me why is this the case? I am using Ubuntu.

You might have started Jack without Alsa-Midi support. I always start Jack via the command line like this:

Code: Select all

jackd -d alsa --device hw:0 &

Meaning:
"-d alsa" means: use Alsa as audio driver (don't use the option "--driver", that won't work for some strange reason, maybe jack1 vs. jack2 thing...)
"--device hw:0" means: use audio device with number 0 in my system for sound
"&" means: run in the background so I can close the terminal window with the command "exit" without killing Jack

Good luck!

You have to Enable ALSA Sequencer support and exit from Qjackctl to make the change to have effect.

@LAM: I totally missed that option in Qjackctl!

Glad it was helpful.

I discovered this when I started my journey in Linux audio for the exact opposite reason, I wanted to get rid of ALSA midi ports spamming in my graph.
