/*! \mainpage Rosegarden global design
Rosegarden is split into 3 main parts:
\section base Base
The base library holds all of the fundamental "music handling"
structures, of which the primary ones are Event, Segment, Track,
Instrument and Composition. It also contains a selection of utility
and helper classes of a kind that is not specific to any particular
GUI. Everything here is part of the Rosegarden namespace, and there
are no dependencies on KDE or TQt (although it uses the STL heavily).
The keyword for the basic structures in use is "flexibility". Our
Event objects can be extended arbitrarily for the convenience of GUI
or performance code without having to change their declaration or
modify anything in the base library. And most of our assumptions
about the use of the container classes can be violated without
disastrous side-effects.
\subsection musicstructs Music Structures
- \link Event Event\endlink is the basic musical element. It's more or less a
generalization of the MIDI event. Each note or rest, each key
change or tempo change, is an event: there's no "note class" or
"rest class" as such, they are simply represented by events whose
type happens to be "note" or "rest".
Each Event has a type code, absolute time (the moment at which the
Event starts, relative only to the start of the Composition) and
duration (usually non-zero only for notes and rests), together
with an arbitrary set of named and typed properties that can be
assigned and queried dynamically by other parts of the
application. So, for example, a note event is likely to have an
integer property called "pitch", and probably a "velocity", as
well as potentially many others -- but this is not fixed anywhere,
and there's no definition of what exactly a note is: client code
is simply expected to ignore any unrecognised events or properties
and to cope if properties that should be there are not.
- \link Segment Segment\endlink is a series of consecutive Events found on the same Track,
automatically ordered by their absolute time. It's the usual
container for Events. A Segment has a starting time that can be
changed, and a duration that is based solely on the end time of
the last Event it contains. Note that in order to facilitate
musical notation editing, we explicitly store silences as series
of rest Events; thus a Segment really should contain no gaps
between its Events. (This isn't checked anywhere and nothing will
break very badly if there are gaps, but notation won't quite work
- \link Track Track \endlink is much the same thing as on a mixing table, usually
assigned to an instrument, a voice, etc. Although a Track is not
a container of Events and is not strictly a container of Segments
either, it is referred to by a set of Segments that are therefore
mutually associated with the same instruments and parameters. In
GUI terms, the Track is a horizontal row on the main Rosegarden
window, whereas a Segment is a single blue box within that row, of
which there may be any number.
- \link Instrument Instrument \endlink corresponds broadly to a MIDI or Audio channel, and is
the destination for a performed Event. Each Track is mapped to a
single Instrument (although many Tracks may have the same
Instrument), and the Instrument is indicated in the header at the
left of the Track's row in the GUI.
- \link Composition Composition\endlink is the container for the entire piece of music. It
consists of a set of Segments, together with a set of Tracks that
the Segments may or may not be associated with, a set of
Instruments, and some information about time signature and tempo
changes. (The latter are not stored in Segments; they are only
stored in the top-level Composition. You can't have differing
time signatures or tempos in different Segments.) Any code that
wants to know about the locations of bar lines, or request
real-time calculations based on tempo changes, talks to the
See also docs/data_struct/units.txt for an explanation of the units we
use for time and pitch values. See docs/discussion/names.txt for some
name-related discussion. See docs/code/creating_events.txt for an
explanation of how to create new Events and add properties to them.
The base directory also contains various music-related helper classes:
- The NotationTypes.[Ch] files contain classes that help with
creating and manipulating events. It's very important to realise
that these classes are not the events themselves: although there
is a Note class in this file, and a TimeSignature class, and Clef
and Key classes, instances of these are rarely stored anywhere.
Instead they're created on-the-fly in order to do calculation
related to note durations or time signatures or whatever, and they
contain getAsEvent() methods that may be used when an event for
storage is required. But the class of a stored event is always
simply Event.
The NotationTypes classes also define important constants for the
names of common properties in Events. For example, the Note class
contains Note::EventType, which is the type of a note Event, and
Note::EventRestType, the type of a rest Event; and Key contains
Key::EventType, the type of a key change Event, KeyPropertyName,
the name of the property that defines the key change, and a set
of the valid strings for key changes.
- BaseProperties.[Ch] contains a set of "standard"-ish Event
property names that are not basic enough to go in NotationTypes.
- \link SegmentNotationHelper SegmentNotationHelper\endlink
and \link SegmentPerformanceHelper SegmentPerformanceHelper\endlink
do tasks that
may be useful to notation-type code and performer code
respectively. For example, SegmentNotationHelper is used to
manage rests when inserting and deleting notes in a score editor,
and to create beamed groups and suchlike; SegmentPerformanceHelper
generally does calculations involving real performance time of
notes (taking into account tied notes, tuplets and tempo changes).
These two lightweight helper classes are also usually constructed
on-the-fly for use on the events in a given Segment and then
discarded after use.
- \link Quantizer Quantizer\endlink is used to quantize event timings and set quantized
timing properties on those events. Note that quantization is
non-destructive, as it takes advantage of the ability to set new
Event properties to simply assign the quantized values as separate
properties from the original absolute time and duration.
\section gui GUI
The GUI directory builds into a KDE/TQt application. Like most KDE
applications, it follows a document/view model. The document (class
RosegardenGUIDoc, which wraps a Composition) can have several views
(class RosegardenGUIView), although at the moment only a single one is
This view is the TrackEditor, which shows all the Composition's
Segments organized in Tracks. Each Segment can be edited in two ways:
notation (score) or matrix (piano roll).
All editor views are derived from EditView. An EditView is the class
dealing with the edition per se of the events. It uses several
- Layout classes, horizontal and vertical: these are the classes
which determine the x and y coordinates of the graphic items
representing the events (notes or piano-roll rectangles). They
are derived from the LayoutEngine base-class in the base library.
- Tools, which implement each editing function at the GUI (such as
insert, erase, cut and paste). These are the tools which appear on
the EditView's toolbar.
- Toolbox, which is a simple string => tool map.
- Commands, which are the fundamental implementations of editing
operations (both menu functions and tool operations) subclassed
from KDE's Command and used for undo and redo.
- a canvas view. Although this isn't a part of the EditView's
definition, both of the existing edit views (notation and matrix)
use one, because they both use a TQCanvas to represent data.
- LinedStaff, a staff with lines. Like the canvas view, this isn't
part of the EditView definition, but both views use one.
There are currently two editor views:
- NotationView, with accompanying classes NotationHLayout,
NotationVLayout, NotationStaff, and all the classes in the
notationtool and notationcommands files. These are also closely
associated with the NotePixmapFactory and NoteFont classes, which
are used to generate notes from component pixmap files.
- MatrixView, with accompanying classes MatrixHLayout,
MatrixVLayout, MatrixStaff and other classes in the matrixview
The editing process works as follows:
[NOTE : in the following, we're talking both about events as UI events
or user events (mouse button clicks, mouse move, keystrokes, etc...)
and Events (our basic music element). To help lift the ambiguity,
"events" is for UI events, Events is for Event.]
-# The canvas view gets the user events (see
NotationCanvasView::contentsMousePressEvent(TQMouseEvent*) for an
example). It locates where the event occured in terms of musical
element: which note or staff line the user clicked on, which pitch
and time this corresponds to, that kind of stuff. (In the
Notation and Matrix views, the LinedStaff calculates mappings
between coordinates and staff lines: the former is especially
complicated because of its support for page layout.)\n
-# The canvas view transmits this kind of info as a signal, which is
connected to a slot in the parent EditView.
-# The EditView delegates action to the current tool.\n
-# The tool performs the actual job (inserting or deleting a note,
Since this action is usually complex (merely inserting a note requires
dealing with the surrounding Events, rests or notes), it does it
through a SegmentHelper (for instance, base/SegmentNotationHelper)
which "wraps" the complexity into simple calls and performs all the
hidden tasks.
The EditView also maintains (obviously) its visual appearance with the
layout classes, applying them when appropriate.
\section sequencer Sequencer
The sequencer directory also builds into a KDE/TQt application, but one
which doesn't have a gui. The Sequencer can be started automatically
by the main Rosegarden GUI or manually if testing - it's sometimes
more convenient to do the latter as the Sequencer needs to be connected
up to the underlying sound system every time it is started.
The Sequencer interfaces directly with \link AlsaDriver ALSA\endlink
and provides MIDI "play" and "record" ports which can be connected to
other MIDI clients (MIDI IN and OUT hardware ports or ALSA synth devices)
using any ALSA MIDI Connection Manager. The Sequencer also supports
playing and recording of Audio sample files using \link JackDriver Jack\endlink
The GUI and Sequencer communicate using the KDE DCOP communication framework.
Look in:
- \link rosegardenguiiface.h gui/rosegardenguiiface.h\endlink
- \link rosegardensequenceriface.h sequencer/rosegardensequenceriface.h\endlink
for definitions of the DCOP interfaces pertinent to the Sequencer
and GUI. The main DCOP operations from the GUI involve starting and
stopping the Sequencer, playing and recording, fast forwarding and
rewinding. Once a play or record cycle is enabled it's the Sequencer
that does most of the hard work. Events are read from (or written to, when recording)
a set of mmapped files.
The Sequencer makes use of two libraries libRosegardenSequencer
and libRosegardenSound:
- libRosegardenSequencer holds everything pertinent to sequencing
for Rosegarden including the
Sequencer class itself. This library is only linked into the
Rosegarden Sequencer.
- libRosegardenSound holds the MidiFile class (writing and reading
MIDI files) and the MappedEvent and MappedComposition classes (the
communication class for transferring events back and forth across
DCOP). This library is needed by the GUI as well as the Sequencer.
The main Sequencer state machine is a good starting point and clearly
visible at the bottom of rosegarden/sequencer/main.cpp.
