This is where it all happens, this is where you can make music :-)
The Pattern Editor allows you to create and modify the pattern selected in the Sidebar of the Song Editor by adding/removing notes and tuning a number of per-note properties, like velocity and pan. The Pattern Editor can be used in two modes: as Drumkit Editor or as Piano Roll Editor. You can switch between these two by clicking the and button (located on the top-right of the Pattern Editor).
If you are editing a pattern in Selected Pattern Mode you will always hear the pattern you are editing when you playback is rolling.
If you are working in Stacked Pattern Mode you will hear the active pattern(s), not necessarily the pattern you are currently editing.
The left combo box represents the numerator of your current measure. You can enter a decimal numerator, like
4.5/4, but since resolution in Hydrogen is limited,
some values are not supported and can not be entered.
Hydrogen supports (only) the following denominators (right combo box):
Typing / within the numerator (first combo box) also you to quickly jump to the denominator.
If you are working
with a resolution of
: when checked Hydrogen will play back samples as they are being added to the pattern (even if transport is not rolling).
When disabled you will still hear the preview sound when clicking on the instrument name in the Sidebar. Be sure to click at the left-most position - where the preview is silent - in case you don't want to get disturbed.
: enables/disables quantization. When checked, notes recorded using incoming MIDI messages or Hydrogen's Virtual Keyboard will automatically respect the grid resolution currently applied, just like notes inserted by clicking.
The section on the left shows you what drumkit is currently selected (GMRockKit by default) and below that you can see the instruments that are part of this kit.
Left-clicking the box containing the instrument name will play back a sample of the instrument. Which layer will be select depends on the horizontal position of the mouse click representing zero velocity to the left and maximum velocity to the right. In addition, each instrument has its own set of features that are accessible by right-clicking the instrument. From the context menu that pops up you can select.
Delete notes: removes all notes for this instrument in this pattern.
Depending on the choice you make (
Randomize velocity: automatically apply a pseudo-random velocity to each note of that instrument in the pattern.
The more velocity you set on the instrument, the more Hydrogen will hit “hard” on that instrument when played.
Select notes: will select all the notes played on this instrument in the current pattern. They can then be copied, moved etc. in the Pattern Editor main area.
Edit all patterns: this section of the menu has actions which operate on notes played by the instrument in all the patterns of the song.
Cut notes: remove all notes played on this instrument, in all patterns, and keep them in the clipboard.
Copy notes: copy all notes played on this instrument, in all patterns, to the clipboard.
Paste notes : paste a multi-pattern selection from the clipboard to this instrument.
Delete notes: delete all the notes associated with this instrument, without affecting the clipboard.
These can be used together to change the instrumentation of a song, entirely replacing one instrument with another by just copy and pasting the notes to a new instrument.
Instrument: this section of the menu has actions which operate on the instrument as a whole:
Rename instrument: change the name of the instrument.
Delete Instrument: well, deletes the instrument ;-)
The button mutes the instrument and solos it.
The order of the instruments can be rearranged by simply dragging an instrument up/down in the list and dropping it on a new position within the drumkit. Doing so will not change the sequence of notes you have created for that instrument, nor will it change anything about the song or pattern you are working on.
It will however, have an impact on the MIDI note mapping.
Rearranging the instruments will also mess up the per-instrument JACK output ports. Be sure to have your drumkit set up before starting wiring.
