1.0.0

The themes of this release are:

• New JavaScript version of Radiant Voices.
• Support for new modules, controllers, options, and curves in SunVox 1.9.6c.
• Improved general compatibility with the SunVox file format.
• Improved documentation of the SunVox file format.
• Radiant Voices API improvements.

Major change: genrv code generator

To support porting Radiant Voices to more languages than just Python, and keeping these ports in sync with new versions of SunVox, this release introduces a new code-generation tool, genrv.

genrv is written in Python, and uses Jinja2 templates to generate source code in various target languages, based on a spec written in YAML.

The generated code is run through code-formatting tools, saved directly into the final package structure, and committed to the git repository as any other code would be.

Base classes for all module types are generated this way. They include controllers, options, and controller value enums. The actual classes for each module inherit from these base classes and add module-specific behavior maintained by hand.

Major change: JavaScript port

Radiant Voices now has a JavaScript port, written in TypeScript. It pairs well with the JavaScript/WebAssembly version of the SunVox library.

It is not a 1-to-1 port from the Python version, although it is designed to allow you to do the same things.

As of this release, each version has strengths and weaknesses compared to the other. Over time, we will work towards parity as we strive toward 100% compatibility with SunVox.

0.4.0.dev1 (2018-03-11)

Additions

• Adds documentation about the SunVox file format.
• Adds equality checking to Range.
• Adds Module.midi_in_always attribute, defaulting to False. When True, the module will respond to MIDI events regardless of whether it's selected in the SunVox UI.
• Adds Module.midi_in_channel attribute, defaulting to 0 (all channels). Set to 1-16 to make the module respond to only a specific MIDI channel.

• Adds Sampler.Sample.loop_sustain flag.
• Adds Sampler.ignore_velocity_for_volume option.
• Adds Container.clone() method.
• Adds Project.pattern_lines() method, which iterates over a range of project lines and yields information about the active pattern lines for each project line.
• Adds Pattern.source_method() and PatternClone.source_method(), to determine the source pattern for any given pattern or pattern clone.

Changes

• Python 3.6 is now required.
• While writing files, CHFF and CHFR chunks will not be written if they always have a value of 0.
• AnalogGenerator.unsmooth_frequency_change option is now inverted to .smooth_frequency_change.
• Updates Sampler and Sampler.Envelope to support SunVox 1.9.3 format. When a pre-1.9.3 formatted Sampler is loaded, it will be upgraded to 1.9.3 format.
• More detailed exception message when attempting to set an out-of-range value to a controller.
• Ignores chunk types no longer used by modern SunVox versions: PSYN, PCTL, and PAMD.
• Ignores value of CHNK when reading module-specific chunks.
• Does not write the optional -1 to the end of SLNK chunks.
• Uses the value mapping curve when converting a MultiCtl.value to downstream controllers.
• Updates MetaModule.play_patterns, which is now of type MetaModule.PlayPatterns instead of bool. This introduces support for the new MetaModule.PlayPatterns.on_no_repeat value.
• Uses the Fruchterman-Reingold layout algorithm from NetworkX for auto-layout of modules, not PyGraphviz neato algorithm. This affects the arguments accepted by Project.layout().
• Improves variable names generated from MetaModule user defined controller labels.

Fixes

• SMIN (module MIDI output device name) is now correctly read and written.
• SMII and SMIC chunks are now encoded as unsigned int32 (was previously signed).
• Strings now use UTF-8 encoding.
• All module types now have a correct default .flags attribute.
• After MetaModule.update_user_defined_controllers() is called, user defined controllers will have correct value_type set. (This avoids errors such as 44100 being out of the 0..32768 range.)
• In MetaModule, when a user defined controller mapping points to a non-existent module, the mapping will be ignored. (Was throwing an AttributeError)
• When Module options are loaded from older projects, assume 0 as a default value if there are not enough bytes. (Was throwing an IndexError)
• Range validation for Lfo.freq and Vibrato.freq now depends on the value of the frequency_unit controller. Some modules created in earlier versions of SunVox have out-of-range values. These are only warned about using logging, instead of the standard behavior of raising an exception.
• Writes correct value of CHNK when writing module-specific chunks.
• Default to signed 8-bit int when a CHFF value was 0.

0.3.0 (2017-04-18)

Additions

• Adds 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

• Fixes algorithm for propagating MultiCtl.value changes to mapped controllers.
• Fixes algorithm for reflecting mapped controllers back to MultiCtl.value.

0.2.0 (2017-04-02)

Additions

• Adds Controller.pattern_value() instance method, to map a controller's value to a pattern value in the range of 0x0000-0x8000.
• Adds ALL_NOTES constant to see if a NOTECMD is a note or a command. (Example: if some_note in ALL_NOTES: ...)
• Adds tabular_repr() instance methods to Note and Pattern, returning a tabular representation suitable for inclusion in text documents.
• Adds behaviors attribute to all module classes, describing the types of information each module can send and receive.
• Adds package-specific exception base classes to rv.errors.
• Adds support for reading, writing, and modifying controller MIDI mappings.
• Adds a MultiCtl.macro() static method, for quickly creating a MultiCtl that controls several similar controllers on connected modules.
• Adds a MultiCtl.reflect() instance method, for setting a MultiCtl's value based on the destination controller mapped at a given index.
• Adds # TODO: ... notes to indicate unimplemented features.
• Allows 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.
• Adds ArrayChunk.set_via_fn() method, for setting various curves using the output of a function.
• Adds DRUMNOTE, BDNOTE, HHNOTE, and SDNOTE enumerations to DrumSynth class, providing note aliases for easier programming of drum sequences.
• Adds Pattern.set_via_fn() and .set_via_gen() instance methods, for altering a pattern based on the output of a function or generator.

Changes

• Renames Output module's module group to "Output".
• When using Project.layout(), default to using dot layout engine.
• Uses a direct port of SunVox's algorithm for mapping MultiCtl values to destination controllers.
• Uses 1.9.2.0 as SunVox version number when writing projects to files.
• Allows using separate x/y offsets and factors during Project.layout()

Fixes

• Uses same sharp note notation as used by SunVox (lowercase indicates sharp).
• Honor prog keyword arg when passed into Project.layout() method.
• Does not require pattern x or y to be divisible by 4.
• Assigns correct controller number to user-defined controllers on MetaModule.
• Corrects the max value allowed in a MultiSynth velocity/velocity curve.
• Moves pygraphviz from requirements/base.txt to .../tools.txt to be more Windows-friendly.
