Jack issue after upgrading to Ubuntu 14.04

Saturday, September 20th, 2014

After upgrading Ubuntu to 14.04 I had two problems.

– No sound from Spotify via webbrowser anymore.

Solved by: Installing pulseaudio-module-jack (4.0-0ubuntu11). This caused my PulseAudio JACK Sink to be available again. In PulseAudio Volume Control I then had to set the ALSA plug-in (under tab Afspelen/Play) to Jack sink.

– No connection anymore between my midi keyboard and the Jack Mixer. I could not control the volume in Jack Mixer via my keyboard anymore. The connection was visible in the JACK Audio Connection Kit via Patchbay (loaded via my patchbay configuration file patchbaydefault.xml), but did not get propagated to my connections in the JACK Audio Connection Kit. This was caused by a change in the name of the plug for my midi keyboard. Probably due to some previous re-installing.

Old value in patchbaydefault.xml:

<socket exclusive=”off” client=”a2j” type=”jack-midi” name=”a2j_Oxygen_61″><plug>Oxygen 61 \[20\] \(capture\): Oxygen 61 MIDI 1</plug></socket>

New value that worked:

<socket exclusive=”off” client=”a2j” type=”jack-midi” name=”a2j_Oxygen_61″><plug>Oxygen 61 \[24\] \(capture\): Oxygen 61 MIDI 1</plug></socket>

Solved by: Deleting the plugs via Patchbay and re-creating the connection. I probably also could have changed the xml file directly.

Old song text

Friday, May 24th, 2013

I found an old song text that I wrote when I was studying.

There is a bug on the wall of my room
It’s staring at me what is it gonna do?
It’s sure looking hungry. I don’t hope he’ll eat me.
Scary little bug is looking at me
Scary little bug is gonna get me
Scary little bug is gonna eat me
I aim with my shoe at the beast on the wall
Still looking scary I’d better not stall
There goes my shoe. It’s flying. It’s airborne.
Scary little bug is looking at me
Scary little bug is gonna get me
Scary little bug is gonna eat me
Shoe’s doing good it is nearing the beast
The insect is scared now or worried at least
But it’s too late and my shoe hits it’s ugly little head
Scary little bug was looking at me
But it’s pretty sure that he won’t get me
I relieved him of his being ugly
But the f*cking insect stained my wall
I think that’s the worst of it all

Ubuntu audio with Jack

Saturday, October 27th, 2012

Below is an overview of my current audio set up in Ubuntu with Jack. I mainly use it to fiddle along with internet radio on my midi keyboard. TimeMachine can record anything interesting from up to 10 seconds ago and onwards. The script in the lower screen does the set up. Mixer slides and qsynth channels with different instruments are controlled from the keyboard.

Midi keyboard in Ubuntu

Monday, April 9th, 2012

There aren’t a lot of good tutorials on how to set up your midi keyboard in Ubuntu. Here is how I did it.

  • Get a midi keyboard (duh!). Mine is an M-AUDIO Oxygen 61.
  • Install Jack Audio, it connects your keyboard with your synthesizer software.
  • Install Bristol, it provides a good set of synthesizers.
  • OPTIONAL install monoBristol, it provides a GUI to Bristol to start up other instruments.

This should give you all you need to start playing your keyboard. However, you would need to start up Jack Audio and Bristol separately every time and also connect your midi keyboard to your synthesizer software and your software to your speakers via Jack Audio each time. Fortunately it is easy to script this in Linux, since there are command line equivalents for all steps.

Here is my script that fires up a Hammond Organ and a Rhodes Bass Piano at the same time 🙂

O, and off course all this costs EUR 0,00 because the software is open source…
