We just composed some music in the previous article, and it’s time to beat some drums now. Hydrogen is a cool program —— you don’t need to know anything about music to enjoy it ! (like me). It gives you the ability to compose tracks of drum beats, like what you find in a usual song, the tracks may be repeated again and mixed with other tracks given in the timeline to produce the final track. It has a eye-catching GUI too. The version 0.9.3 which i’m using (which is also the last stable edition), uses best out of Qt 3.

********You can download the source from here. Typing in the command line, inside the source directory (after extracting),
./configure && make && sudo make install
should install the program, you can always see my article on “compiling from source” if necessary.
*********Without using the source, you can use already available binaries. It’s so popular that your distro will have a pre-compiled binary. Type,
apt-get hydrogen (for debian-based systems (ex: ubuntu))
yum install hydrogen (for red hat, mandriva, suse linux)
should install version 0.9.3
Dependencies: Notable dependencies are: alsa,qt3,raptor,flac,sndfile,lrdf
Importing drum kits
.h2drumkit files importing
You can download drum kits from the sourceforege page. After downloading, you start hydrogen, click view on the menu bar tab, and click on the drumkit manager, so the following dialog box appears. Click on the import tab, and browse for the .h2drumkit file you have downloaded. Click on the load tab and select and load your new drumkit.
Development version (0.9.4 beta 3)
The beta version 0.9.4 uses Qt 4.4, but i’m unable to install it as my Qt is 4.3. (+ only source is available for the fedora, and it uses scons to compile the program, which cannot differentiate my Qt4.3.4 from Qt 3.3.8 and I know nothing about editing scons files), anyway I won’t be positive about a yet beta stage edition. You can download it here.
A help on how to install is given in this page.
