The <span class="application">Rosegarden</span> matrix editor enables you to view and edit
3
music in a simple, logical format: each note represented as a
4
block in a grid, at a height corresponding to the pitch.

Each matrix editor window shows a single segment. To edit a
8
segment, just right-click on it in the main canvas and select
9
the matrix editor from the menu. Alternatively, you can
10
configure Rosegarden to make the matrix editor the default
11
editor available when you double-click on a segment.

13
The matrix view contains Grid and Quantize menus in its main
15
</p><p>The Grid menu controls the size of the visible grid in the
16
background of the matrix view, as well as the time resolution
17
used when entering and moving notes. After you set it to a
18
particular time value, the normal note insertion and drag
19
operations will then snap automatically to grid points spaced at
20
that time width. You can override the snap-to-grid effect
21
temporarily by holding down Shift during editing, or you can
22
disable it by setting the Grid menu to None.
23
</p><p>The Quantize menu works rather differently. Rather than
24
controlling the behaviour of other editing tools, it actually
25
performs an action. When you change the value in this menu, the
26
selected notes -- or the whole segment if nothing is selected
27
-- will immediately be quantized using a grid quantizer of the
29
</p><p>The Quantize menu also shows you continuously what
30
resolution the current segment or selection is quantized to.
31
For example, if you select a set of notes that start on
32
consecutive quarter-note beats, the Quantize menu will update
33
itself to show 1/4, as this is the coarsest resolution
34
consistent with the existing quantization of the current
