Create, read, modify, and write SunVox files.
Project description
Overview of Radiant Voices
==========================
Part of the Metrasynth_ project.
.. _Metrasynth: https://metrasynth.github.io/
Radiant Voices provides tools to
**create, read, modify, and write SunVox files**.
This includes project files ending in ``.sunvox``,
and module/synth files ending in ``.sunsynth``.
SunVox data structures and APIs
-------------------------------
Radiant Voices has nearly 100% coverage of
all data structures used by SunVox files,
exposing a "Pythonic" API for creating and manipulating
those structures.
Using the API, you can do things not possible
with the standard SunVox interface or the SunVox DLL, such as:
- `algorithmic composition`_
- parametric synth/module design
- structure and complexity analysis
- automatic `graph layout`_ of modules
- and more...
Our collective imagination is the limit!
.. _algorithmic composition:
https://en.wikipedia.org/wiki/Algorithmic_composition
.. _graph layout:
https://en.wikipedia.org/wiki/Graph_drawing
Interaction with the SunVox DLL
-------------------------------
By combining Radiant Voices with sunvox-dll-python_,
one can also create alternative editing and performance tools
to use alongside, or instead of, the official SunVox app.
The two packages work together to provide convenient high-level
APIs for loading project and module objects directly into
playback slots managed by the SunVox DLL.
Some possibilities might include:
- alternative project editors
- generative_ sound design using `genetic algorithms`_
- network-enabled performance tools

SunVox file format documentation
--------------------------------
Radiant Voices intends to serve as a *de facto* source of documentation
about the format, as there is currently
`no official documentation for the SunVox file format`_.
.. _no official documentation for the SunVox file format:
http://www.warmplace.ru/forum/viewtopic.php?t=1943#p5562
The interpretation of SunVox file formats is based on a mix of "clean room"
style inspection of what SunVox writes to disk when a file is edited
a specific way, as well as the
`most recent BSD-licensed source code for the SunVox audio engine`_.
.. _most recent BSD-licensed source code for the SunVox audio engine:
https://github.com/warmplace/sunvox_sources
Requirements
------------
- Python 3.5
- OS supported by `sunvox-dll-python`_, if working with SunVox DLL.
- GraphViz_, if you want to make use of module auto-layout features.
.. _GraphViz:
http://www.graphviz.org/
Quick start
-----------
The "hello world" example will construct a SunVox project in memory
containing a FM module connected to the Output module.
It will then load it into the SunVox DLL and send a single note-on command
to the FM module::
$ pip install radiant-voices
$ git clone https://github.com/metrasynth/radiant-voices
$ cd radiant-voices/examples
$ python helloworld.py
About SunVox
------------
From the `SunVox home page`_:
SunVox is a small, fast and powerful modular synthesizer with pattern-based sequencer (tracker).
It is a tool for those people who like to compose music wherever they are, whenever they wish.
On any device. SunVox is available for Windows, OS X, Linux, Maemo, Meego, Raspberry Pi,
Windows Mobile (WindowsCE), PalmOS, iOS and Android.

Changelog
=========
0.3.0 (2017-04-18)
------------------
Additions
.........
- Add ``propagate`` argument to ``MultiCtl.reflect()``.
Defaults to ``True`` which causes the new ``MultiCtl.value`` to
immediately propagate to all mapped controllers,
including the one that was just reflected.
Set to ``False`` if you only want to set ``MultiCtl.value``
without propagating to mapped controllers.
- Pass a value for ``initial`` when calling ``MultiCtl.macro()`` to
set and propagate an initial value. Default behavior is to not set a value.
Changes
.......
- The ``repr`` of a ``CompactRange`` instance now shows that class name,
instead of ``Range``.
Fixes
.....
- Fix algorithm for propagating ``MultiCtl.value`` changes to
mapped controllers.
- Fix algorithm for reflecting mapped controllers back to ``MultiCtl.value``.
0.2.0 (2017-04-02)
------------------
Additions
.........
- Add ``Controller.pattern_value()`` instance method, to map a controller's
value to a pattern value in the range of 0x0000-0x8000.
- Add ``ALL_NOTES`` constant to see if a ``NOTECMD`` is a note or a command.
(Example: ``if some_note in ALL_NOTES: ...``)
- Add ``tabular_repr()`` instance methods to ``Note`` and ``Pattern``,
returning a tabular representation suitable for inclusion in text documents.
- Add ``behaviors`` attribute to all module classes, describing the
types of information each module can send and receive.
- Add package-specific exception base classes to ``rv.errors``.
- Add support for reading, writing, and modifying controller MIDI mappings.
- Add a ``MultiCtl.macro()`` static method, for quickly creating a
``MultiCtl`` that controls several similar controllers on connected modules.
- Add a ``MultiCtl.reflect()`` instance method, for setting a ``MultiCtl``'s
value based on the destination controller mapped at a given index.
- Add ``# TODO: ...`` notes to indicate unimplemented features.
- Allow property-style access to user-defined controllers on ``MetaModule``s
using a ``u_`` prefix. For example, if there's a user-defined controller
named "Attack", it will be accessible via the ``.u_attack`` property.
- Add ``ArrayChunk.set_via_fn()`` method, for setting various curves using
the output of a function.
- Add ``DRUMNOTE``, ``BDNOTE``, ``HHNOTE``, and ``SDNOTE`` enumerations to
``DrumSynth`` class, providing note aliases for easier programming of
drum sequences.
- Add ``Pattern.set_via_fn()`` and ``.set_via_gen()`` instance methods,
for altering a pattern based on the output of a function or generator.
Changes
.......
- Rename ``Output`` module's module group to ``"Output"``.
- When using ``Project.layout()``, default to using ``dot`` layout engine.
- Use a direct port of SunVox's algorithm for mapping ``MultiCtl`` values
to destination controllers.
- Use 1.9.2.0 as SunVox version number when writing projects to files.
- Allow using separate x/y offsets and factors during ``Project.layout()``
Fixes
.....
- Use same sharp note notation as used by SunVox (lowercase indicates sharp).
- Honor ``prog`` keyword arg when passed into ``Project.layout()`` method.
- Do not require pattern ``x`` or ``y`` to be divisible by 4.
- Assign correct controller number to user-defined controllers on
``MetaModule``s.
- Correct the max value allowed in a ``MultiSynth`` velocity/velocity curve.
- Move ``pygraphviz`` from ``requirements/base.txt`` to ``.../tools.txt``
to be more Windows-friendly.
0.1.1 (2016-11-09)
------------------
- Fix upload to PyPI.
0.1.0 (2016-11-09)
