Getting Rosegarden to work in Ubuntu (Gnome)

I am one of those many people out there who had trouble in getting Rosegarden to “sing” in Ubuntu under Gnome Window Manager. Finally after trying a lot of permutations and combinations, I got Rosegarden to work. I made this post to share what I did so that others don't have to go through the same trouble I did!

So let's proceed.

Required software

Rosegarden requires some other applications to be installed in your system. So before you fire up Rosegarden ensure that you have the following:

  1. qjackctl
  2. qsynth
  3. rosegarden

If you don't have any of these you could execute this:

$ sudo apt-get install qjackctl qsynth rosegarden fluid-soundfont-gm

Ok, now we have everything we need. Let's proceed to the configuration steps:

Start the Jack server

(Somehow not using sudo gave me problems)

$ sudo qjackctl &

Jack Audio Connection Kit setup

Click on Setup
Here are the settings I used:
Setup - JACK

Start the Jack server

JACK Audio Connection Kit

Start the synthesizer

$ sudo qsynth &

QSynth setup

MIDI Setup

Setup - Midi

Audio Setup

Setup - Audio

Soundfonts Setup

Setup - Soundfonts

Start rosegarden

Ok, it's time to fire up Rosegarden.

$ sudo rosegarden &

Configuring Rosegarden

Go to Settings – Configure Rosegarden.

Configure Rosegarden - General

Configure Rosegarden - Midi

Ensure that the connections are right in Jack Audio Connection Kit (Connect):
Connections - JACK - ALSA

Connections - JACK - Audio

Play one of the sample files and you should hear music!
Rosegarden

Troubleshooting

In case your Jack server is not running, you might want to execute this command and then start the Jack server:

$ sudo /sbin/alsa force-reload
