Hydrogen is a virtual drum computer and sequencer for GNU / Linux . There are now versions for Windows and macOS (Intel only). In addition to standard functions for drum software, Hydrogen offers some professional functions such as full control via MIDI and freely definable samples . Samples can be combined into libraries that can be passed on as files. Under Linux, Hydrogen is compatible with the JACK sound server . This means that Hydrogen can also be synchronized with other applications connected to JACK.
Hydrogen is developed by Alessandro Cominu. The source code is available under the GNU General Public License . The graphical user interface uses the Qt library .
Concept and functionality
In Hydrogen, drum notes can be combined into rhythmic figures, so-called patterns, in a matrix editor. The length of these figures, which are comparable to bars, is adjustable, so in addition to the 4-quarter time common in pop music, 3-quarter or 5-quarter time figures can also be composed. The patterns can be played in endless loops or put together in a song editor to create defined processes. Several patterns can be played at the same time. The sounds used can be defined in an instrument editor and, from version 0.9.5, can also be edited with a simple tool. The program also has a mixer in which effect plug-ins in LADSPA format can also be integrated. Under Linux, all mixer channels can also be output individually via the JACK audio server.
Finished songs or even individual patterns can be exported directly from Hydrogen as a file in .WAV format.
From version 0.9.5, Hydrogen also offers a piano roll mode in its matrix editor, in which notes in different pitches can be created for the individual sound samples. This allows you to compose melodic patterns in Hydrogen, which can control percussion samples or melodic instruments such as bass or organ sounds.
