Cardinal 是一款免费的开源虚拟模块合成器插件，提供 JACK 独立版本以及适用于 FreeBSD、Linux、macOS 和 Windows 的 AU、LV2、VST2 和 VST3 音频插件。
它基于广受欢迎的 VCV Rack，但专注于打造一个完全独立的插件版本。
更具体地说，它是一个基于 DPF 的 VCV Rack 插件包装器，直接使用其代码，而非 fork 项目，目标是打造一个功能齐全、功能齐全、完全免费开源的 Rack 插件版本。
有关 Cardinal 存在的原因，请参阅下方"原因"部分，常见问题请查看此 FAQ 文档。
Cardinal 将 Rack、一些第三方模块和一些内部实用程序集成到一个二进制文件中。
所有 Rack 中的"核心"模块都已被 Cardinal 的等效模块所取代，并进行了简化，使其更适合音频插件使用。
Cardinal 不加载外部模块，也不连接到官方的 Rack 库/商店。
为了避免任何商标问题，所有 VCV 品牌标识均已移除（据我们所知）。
VST3 版本正在开发中，已包含在构建过程中，但仍处于实验阶段。
稳定版本
Cardinal 发行版提供 Linux、macOS 和 Windows 的官方版本。
Linux 版本适用于各种架构（armhf、arm64、i686 和 x86_64），macOS 通用版本（arm64 + intel），以及 Windows 32 位和 64 位版本。macOS 和 Windows 版本均提供安装程序。
插件变体
Cardinal 提供 3 种插件变体 - 主插件、合成器和效果器。
它们的性能和行为完全相同，只有 IO 和元数据会有所不同。
这是因为某些主机对哪些插件可以作为乐器和效果器非常严格，因此需要同一插件的不同变体。
FX 和 Synth 版本均有 2 个音频输出，而"主"版本有 8 个。
所有版本均支持 MIDI 输入和输出。
主版本
此版本提供 8 个音频输入和输出以及 10 个 CV 输入和输出。
注意：由于 AU 和 VST2 格式不支持 CV 端口，因此此版本不适用于这些格式。
Synth
此版本提供 2 个音频输出，但没有音频输入或 CV 端口。
插件类型设置为"乐器"。
FX
此版本提供 2 个音频输入和输出，但没有 CV 端口。
插件类型设置为常规的"效果器"。

因为人们会要求它。嗯……它是 Rack。

Cardinal is a free and open-source virtual modular synthesizer plugin, available as JACK standalone and AU, LV2, VST2 and VST3 audio plugin for FreeBSD, Linux, macOS and Windows.
It is based on the popular VCV Rack but with a focus on being a fully self-contained plugin version.
More specifically, this is a DPF-based plugin wrapper around VCV Rack, using its code directly instead of forking the project, with the target of having a proper, self-contained, fully free and open-source plugin version of Rack.
See the why section below for the reasons Cardinal exists, also for frequently asked questions check this FAQ document.
Cardinal contains Rack, some 3rd-party modules and a few internal utilities all in a single binary.
All "Core" modules from Rack have been replaced by Cardinal equivalents, simplified to better work for an audio plugin.
Cardinal does not load external modules and does not connect to the official Rack library/store.
All VCV branding has been removed (to the best of our knowledge) in order to avoid any trademark issues.
The VST3 version is in progress, already part of the build but still experimental.
Stable release
Cardinal releases have official builds for Linux, macOS and Windows.
There are Linux builds for various architectures (armhf, arm64, i686 and x86_64), macOS "universal" (arm64 + intel) and Windows 32 and 64bit builds. Both macOS and Windows builds have an installer.
Plugin variants
Cardinal provides 3 plugin variants - "main", Synth and FX.
They are all equivalent in performance and behaviour, with only the IO and metadata that changes.
This is because some hosts are very strict on which plugins are allowed as instruments vs FX, so separate variants of the same plugin are needed.
FX and Synth variants both have 2 audio outputs, while "main" has 8.
All variants have MIDI input and output support.
Main
This variant provides 8 audio inputs and outputs and 10 CV inputs and outputs.
NOTE: Due to AU and VST2 formats not supporting CV ports, this variant is not available for those formats.
Synth
This variant provides 2 audio outputs but no audio inputs or CV ports.
Plugin type is set as "instrument".
FX
This variant provides 2 audio inputs and outputs, but no CV ports.
Plugin type is set as regular "effect".

Because people will ask for it. It is, well... Rack.
But a couple of modules background's have their colors flipped, because damn we want proper |
