v0.6.11

• No breaking changes, hopefully just better VST support. Please try and report.
• Fix possible MIDI memory issue.
• Add the Faust Box and Signal APIs. Check out tests/test_libfaust*.py) if you're interested! There will be a tutorial eventually.

v0.6.10

• New feature to fetch automation as audio-rate data. Use processor.record_automation = True and processor.get_automation() to get a dictionary.
• New feature to save MIDI processor.save_midi("path/to/my_output.mid"). Use it after rendering.
• Upgrade to JUCE 7, enabling LV2 plugins, although not tested
• Bug fix related to MIDI timing whenbeats=True. This only mattered significantly if the buffer size was large.
• Bug fixes related to VST3 parameters (ignore parameters which aren't automatable or have empty "" name)
• Performance optimization for FaustProcessor and PluginProcessor parameters which aren't automated (they're constant)
• Git repository no longer includes JUCE_6/JUCE_7 because it's just included in JuceLibraryCode

v0.6.9

Non-breaking changes:

• Don't use KissFFT on Windows. This should have a marginal quality improvement for PlaybackWarpProcessor.

v0.6.8

Breaking changes:

• PlaybackWarpProcessor now has an enum config system based on Rubber Band's docs. The code below will maintain backwards compatibility

rb_option = daw.PlaybackWarpProcessor.option
playback_warp_processor.set_options(
    rb_option.OptionTransientsSmooth |
    rb_option.OptionPitchHighQuality |
    rb_option.OptionChannelsTogether
)

Non-breaking changes:

• Fixed a bug related to PlaybackWarpProcessor when warp is off.
• PyPI now includes Windows with Python 3.10

v0.6.7

Breaking change:
convert_to_sec=True kwarg has been refactored into beats=False everywhere.

New features:

• PlaybackWarp Processor can now take audio of a different sample rate if you specify the rate as kwarg sr.
• RenderEngine.render now has a default kwarg beats=False. When True, the duration is measured in beats.

Bug fixes:

• Fix looping-related bad code in PlaybackWarp Processor. The tempo won't fall out of sync now.
• Fix fopen issue in Ableton Clip Info (too many file opens caused a crash).

Demo:

• New examples/dj_mixing/dj.py for DJ transitions. Start with one song at tempo A and fade to another song with tempo B.

v0.6.6

Versions 0.6.7 and above dropped convert_to_sec=True in favor of beats=False.

BPM/PPQN new features:

• load_midi and add_midi_note now take convert_to_sec as a kwarg, which is True by default. This maintains backwards compatibility. When convert_to_sec is False, the notes are added according to their beats, so changes to the Engine's BPM will affect the timing.
• load_midi has a kwarg for clear_previous, which defaults to True, maintaining backwards compatibility.
• RenderEngine's set_bpm can now take a numpy array and an integer PPQN. For example, if the values in the array change every PPQN samples, then the tempo change will be "on the beat."
• Any parameter's set_automation now works with optional second PPQN rate argument.

Other features:

• RenderEngine has remove_processor(name: str). If you really want to remove a processor (and break existing Python references to it), use this.

Bug fixes:

• Fix int cast overflow bug with playback warp processor

v0.6.5

No breaking changes.

• Fix memory leaks (#1, #88). In general, engines and processors should not leak when created over and over again, but some plugins will leak. Feel free to report them to me. TAL-NoiseMaker seems to leak. Serum does not.
• Plugin Processor's load_state() has been improved. Under the hood, it creates a window to the plugin and doesn't show the window to the user. This makes the plugin work correctly (for example Spitfire LABs). (This might address specific plugins such as #67)

v0.6.4

PyPI now has wheels for Linux x86_64 with Python 3.7, 3.8, 3.9, 3.10

Try it in a Google Colab!

v0.6.3

Quick update to v0.6.2: Fix issue when overwriting files with Plugin Processor's save_state(filepath: str)

v0.6.2

New Plugin Processor features:

• open_editor()
• load_state(filepath: str)
• save_state(filepath: str)
• can_set_bus(inputs: int, outputs: int)
• set_bus(inputs: int, outputs: int)

See tests/test_plugins.py for more examples.
