Depending on your Linux distribution you have to change the default wikipedia:JRE to the wikipedia:OpenJDK implementation. For a manual installation execute the follow command:

apt-get install default-jre openjdk-6-jre

If your distribution doesn't do it automatically, you have to change the default Java implementation for all programs with the following command:

update-java-alternatives -s openjdk-6-jre


The module snd-virmidi offers virtual wikipedia:Midi devices which might be necessary to connect jOrgan to other Midi programs (Java supports RawMidi devices only).

To start it explicitely use the following command in a terminal:

modprobe snd-virmidi

To configure Midi routing you'll need an addional package aconnectgui:

sudo apt-get install aconnectgui

Further information is available in the Linux Midi Howto.


On Linux the JRE needs wikipedia:ALSA to support wikipedia:Midi. The Advanced Linux Sound Architecture provides audio and Midi functionality for the Linux operating system. It is included in all current Linux distributions.

The Linux Audio Users Guide gives a good introduction for those who are struggling with audio on Linux.

The Unofficial ALSA Wiki hosts an exhaustive collection of information about ALSA, among other things how to find and identify your devices (e.g. hw:0,2 or front:CARD=Live,DEV=0).


The JACK Audio Connection Kit is a sound server daemon that provides low latency sound connections.
