经过长时间的开发，Astra 是一款多功能软件合成器，能够实现各种独特的音色。
早在 2018 年，当我们着手创建这款乐器时，我们就希望提供尽可能广泛的功能——尽可能地推动技术极限——而不会让它感觉压倒性或无处不在。对我来说，当创作过程被简化时，乐器的最佳点就出现了，而不是因为太多的选项或菜单而过于复杂。

最终，最终用户提出高质量声音的速度是 Astra 最重要的一个因素；繁琐的预设加载时间和缓慢的界面图形无处可寻。几乎所有 Astra 的功能都可以在其开放式界面中同时查看，无需点击复杂的菜单或多个选项卡。可以通过拖动右下角自由调整界面大小。

Astra 有两个主要的、相同的振荡器。每一个都可配置为用于虚拟模拟、FM、颗粒、采样器或基于波表的合成。还有一个副振荡器、噪声发生器、多模式滤波器、两个包络发生器、两个 LFO、一个采样和保持部分以及一个综合效果引擎。下面，让我们更详细地深入研究这些功能。

通过 Splice Creator 计划探索 Astra 以及其他插件和功能的集合。

Astra 中的振荡器
模拟：虚拟模拟振荡器具有锯齿波、方波、三角波和正弦波发生器，带有电平、形状、粗调和微调控制。这种振荡器类型可以与副振荡器同步以创建老式的主音或低音。

FM： FM 振荡器具有四个载波波形，具有用户可加载的主调制器波形和可切换的线性/指数 FM，适用于广泛的声音设计。

颗粒：该颗粒振荡器允许音频文件的小部分被循环，形成自己独特的振荡器。我们提供全面的工厂样本选择，以及用户添加自己声音的能力。

采样器：这个振荡器有一个基本的采样器，它允许任何长达 60 秒的声音跨键映射、循环或反转。通过使用 RESET 选项，可以将音高固定为其原生音符（这在创建分层鼓点或节拍时很有用）。

波表：波表振荡器使用我们的工厂库（主要从我自己的硬件合成器采样）或用户添加的自定义波形生成单周期波形。

以下是您可能需要考虑探索和与振荡器一起使用的其他一些功能：

位于主振荡器右侧的副振荡器具有五种波形（锯齿波、方波 I、方波 II、三角波和正弦波），并且可以在四个八度范围内进行调谐。
有各种不同的滤波器可用，每一种都有独特的声音特性和顺序配置选项。
Astra 的每个双LFO都可以以多达 27 种不同的速率运行，可以与 DAW 的节奏同步，也可以设置为独立运行。有多种不同的波形，您可以再次加载自己的单周期形状。LFO 的深度值可以分配给宏，然后分配给调制轮控制器等设备。
Astra 中的宏
通过单击并将其名称直接拖到宏旋钮之一上，几乎可以将 Astra 中的任何参数分配给四个宏之一。然后，该参数将用它所分配到的宏的本机颜色加下划线。许多控件可以分配给任何一个宏，并且可以通过双击它来自定义其名称。

splice-astra-synth-in-post-宏
将参数分配给宏后，可以通过单击其下方的线条并向左或向右拖动来修改可分配范围。当任何一个宏上有多个参数时，这非常有用。

宏音序器

Astra 最突出的功能之一是它的宏音序器。每个宏都可以在其自己的 32 步音序器通道内使用各种修改器进行自动化——每个通道都可以以自己独特的速率、范围和步数运行。可以通过单击并拖动每个通道上方的定位器来修改步长范围。

splice-astra-synth-in-post-macro-sequencer
泳道序列可以随机化，并且可以通过单击每个泳道右上角的相应图标来加载或保存模式。除了全局摇摆控制之外，还有平滑控制来缓解参数值之间的过渡。单击每个车道右上角的水平点，您可以访问菜单以翻转和递增或减少车道数据。

音符音序器
Astra 的音符音序器的操作方式与宏音序器相同。音高 (P)、速度 (V) 和门 (G) 有单独的通道。步进静音是链接的，并且可以使用 SCALE 菜单将音符数据限制为流行的音阶类型。在车道上单击鼠标右键会生成一个线条工具，并允许写入淡入淡出和统一模式。所有音序器的摇摆值也相互关联。

调制矩阵
最后，让我们介绍一下调制矩阵，它可以通过下面看到的调制矩阵选项卡访问。参数可以拖到十个插槽中的任何一个。包络发生器、LFO、采样和保持、音符（键跟随）、力度、弯音、调制轮和触后值可以通过双击输入，并通过单击每个通道末端的“x”清除。EG1 配置为作为主 VCA，但可以在 mod 矩阵中提供双重用途。

A long time in the making, Astra is a versatile software synth capable of achieving a wide range of unique tones.
When we set out to create this instrument back in 2018, we wanted to provide the widest possible range of functionality—pushing the technical envelope as far as we could go—without making it feel overwhelming or all-over-the-place. For me, the sweet spot with an instrument comes when the creative process is simplified, not overcomplicated with too many options or menus.

Ultimately, the speed at which the end user can come up with high-quality sounds is the single most important factor with Astra; cumbersome preset load times and slow interface graphics are nowhere to be found. Almost all of Astra’s features can be viewed simultaneously in its open-ended interface, without the need to click into complex menus or multiple tabs. The interface can freely be resized by dragging the bottom right corner.

Astra has two main, identical oscillators. Each one is configurable to be used for virtual analog, FM, granular, sampler, or wavetable-based synthesis. There’s also a sub oscillator, noise generator, multi-mode filter, two envelope generators, two LFOs, a sample & hold section, and a comprehensive effects engine. Below, let’s dive into these features and more in a little more detail.

Explore Astra alongside a collection of other plugins and features via the Splice Creator plan.

The oscillators in Astra
Analog: The virtual analog oscillator has saw, square, triangle, and sine wave generators with level, shape, coarse, and fine tuning controls. This oscillator type can be synchronized with the sub oscillator to create old-school lead or bass sounds.

splice-astra-synth-in-post-01-analog
FM: The FM oscillator has four carrier waveforms, with a user-loadable main modulator waveform and switchable linear / exponential FM for a wide scope of sound design.

splice-astra-synth-in-post-fm
Granular: The granular oscillator allows small sections of an audio file to be looped to form their own unique oscillator. We offer a comprehensive selection of factory samples, as well as the ability for a user to add their own sounds.

splice-astra-synth-in-post-granular
Sampler: This oscillator features a basic sampler, which allows any sound up to 60 seconds in length to be mapped across the keys, looped, or reversed. The pitch can be fixed to its native note (which is useful when creating layered drum hits or beats) by using the RESET option.

Wavetable: The wavetable oscillator generates single-cycle waveshapes, either using our factory library (mostly sampled from my own hardware synths) or custom waveforms added by the user.

splice-astra-synth-in-post-wavetable
Below are some other features that you may want to consider exploring and using alongside the oscillators:

The sub oscillator located to the right of the main oscillators has five waveforms (saw, square I, square II, triangle, and sine) and can be tuned across a four-octave range.
There are various different filters available, and each one has unique sonic characteristics and order configuration options.
Each of Astra’s twin LFOs can run at up to 27 different rates, either synced to the DAW’s tempo or set to operate independently. There are a variety of different waveforms, and again you can load your own single-cycle shapes. The LFOs’ depth values can be assigned to a macro, and then a device such as a mod wheel controller.
Macros in Astra
Almost any parameter in Astra can be assigned to one of four macros by clicking and dragging its name directly onto one of the macro knobs. The parameter will then be underlined in the native color of the macro it’s assigned to. Numerous controls can be assigned to any one macro, and its name can be customized by double clicking it.

splice-astra-synth-in-post-macros
When a parameter is assigned to a macro, the assignable range can be modified by clicking the line under it and dragging left or right. This is extremely useful when there are multiple parameters on any one macro.

The Macro Sequencer

One of the most prominent features of Astra is its Macro Sequencer. Each macro can be automated within its own 32-step sequencer lane with a variety of modifiers—each lane can run at its own unique rate, range, and number of steps. The step range can be modified by clicking and dragging the locators above each lane.

splice-astra-synth-in-post-macro-sequencer
Lane sequences can be randomized and patterns can be loaded or saved by clicking the respective icons on the top right of each lane. There are also smoothing controls to ease the transition between parameter values, in addition to a global swing control. Clicking the horizontal dots on the top right of each lane allows you to access a menu to flip and incrementally increase or decrease lane data.

The Note Sequencer
Astra’s Note Sequencer operates in the same manner as the Macro Sequencer. There are individual lanes for pitch (P), velocity (V), and gate (G). Step mutes are linked, and note data can be limited to popular scale types by using the SCALE menu. Right clicking in a lane generates a line tool and allows fades and uniform patterns to be written. Swing values for all of the sequencers are also linked.

The Modulation Matrix
Lastly, let’s cover the Modulation Matrix, which can be accessed via the Mod Matrix tab seen below. Parameters can be dragged into any of ten slots. The envelope generators, LFOs, sample & hold, note (key follow), velocity, pitch bend, modulation wheel, and aftertouch values can be entered by double clicking them, and cleared by clicking the ‘x’ at the end of each lane. EG1 is configured to act as a master VCA, but can serve a dual purpose within the mod matrix.

Hopefully this article gave you a bit of an overview into the different key capabilities that Astra offers. That said, no amount of words can replace firsthand experience—we encourage you to play with the synth yourself, exploring the features and parameters we mentioned above as starting points.
