Theremin是Leon Leon在1928年获得专利的电子仪器。典型的Theremin用户使用两个振荡器-一个振荡器产生一个静态频率，一个变量-并放大这两个信号的差，以产生不同频率的正弦波，从而产生不同的音高。 Theremin使用次级电路来控制幅度。您可以通过调节手相对于Theremin天线的两个天线的位置来控制音高/音量，从而使其成为世界上您演奏但绝不触摸的唯一乐器之一！
Theremin的语气是众所周知的，由于它有些不自然且令人困扰，因此可以在无数恐怖分数中听到。从理论上讲，Theremin产生基本音高作为纯正弦波，而纯正弦波听起来不自然，因为自然界中的大多数声音都带有泛音。
Theremin被认为是世界上最具挑战性的乐器之一。不仅像小提琴那样“无品味”，而且甚至是无弦，其产生的音调不会因无所作为或自然衰减而停止，而是通过手动减小音量来停止。换句话说，要产生断音音符，不仅必须控制起音和保持，而且还必须控制衰减。这与几乎所有其他乐器的工作方式是相反的。
本质上，Theremin是世界上第一台合成器，它使用电子设备“合成”纯净的电子音调。我们致力于通过专注于滑音和颤音之类的东西来重现此乐器的声音和感觉，因为如果没有适当的模拟技术，那么Theremin模拟器将只不过是一个正弦波发生器。
工程
对Theremin进行采样有点违反直觉，因为Theremin的大部分声音与平滑的滑音/幻灯片有关。 Theremin会产生一个连续的信号，该信号只能降低振幅，但永远不会真正停止，因此从一个音高过渡到另一个音高总是会产生滑音，除非先前的音调已被静音。
我们的编程旨在实现许多这种行为。我们的音调是由纯正弦波产生的。您可以在音符之间使用滑音来演奏音符，并且只要您使音符在触发器之间至少衰减一点，就可以演奏更多不同的断音音符。我们的Theremin是单声道的，因此您听到的声音不会超过频率，这是物理Theremin的工作方式。颤音和音量可以通过音高或调制轮控制，以使不自然的信号听起来更人性化。
编写Theremin vst aax音频单元插件并不像听起来那样简单，因为正确地将单声道信号传递至滑音并令人信服地衰减，同时听起来自然且易于控制，这有点平衡。但是，我们认为我们在平衡可控性，易用性和音质方面做得很好，因此最终结果是一款易于演奏且听起来不错的vst乐器。
振幅和颤音可通过音高和/或调制轮单独控制或一起控制。可以将滑音设置为常规或慢速，但是滑音的速度会根据演奏的间隔而降低或提高（以更快的速度更紧密地记下滑音）。包括合唱和混响效果，使您可以创建略有不同的音调。购买的产品包括Windows和Mac VST和AAX版本，以及Mac OS X音频单元版本。音频单元版本需要OS X 10.9（Mavericks）或更高版本。

The theremin is an electronic instrument patented in 1928 by Leon Theremin. The typical theremin users two oscillators – one producing a static frequency, one variable – and amplifies the difference of these two signals to produce sine waves at different frequencies, thus creating different pitches. A theremin uses a secondary circuit to control amplitude. You can control pitch/volume with your hands by adjusting the position of your hands in relation to the two antennas of the theremin, thus making it one of the only instruments in the world that you play but never touch!
The tone of the theremin is well known, and can be heard in countless horror scores because of its somewhat unnatural and haunting tone. Theoretically, a theremin produces a fundamental pitch as a pure sine wave, and pure sine waves sound unnatural because most sounds in nature come with overtones.
The theremin is considered to be one of the worlds most challenging instruments to play. Not only is a theremin “fretless” like a violin, but even stringless, and the tone it produces is not stopped by inaction or through natural decay, but rather by manually decreasing the volume. In other words, to produces staccato notes, one must control not only the attack and hold, but also the decay. This is counterintuitive to how almost every other instrument works.
In essence, the theremin was the worlds first synthesizer, using electronics to “synthesize” a pure electrical tone. We have endeavored to recreate the sound and feel of this instrument by focusing on things like portamento and vibrato, as without properly simulated technique, a theremin simulator would be little more than a sine-wave generator.
ENGINEERING
Sampling a theremin would be somewhat counterintuitive, as the great bulk of a theremin’s sound has to do with smooth portamento/slides. A theremin produces a continuous signal that can only be lowered in amplitude, but never truly stops, so that transitioning from one pitch to another will always produce portamento, unless the previous note has been muted.
Our programming seeks to implement much of this behaviour. Our tones are generated by pure mathematical sine waves. You can play notes with portamento between them, and you can play more distinct staccato notes as long as you allow notes to decay at least a little between triggers. Our theremin is monophonic, so you will never hear more than frequency, which is how a physical theremin works. Vibrato and volume can be controlled by either the pitch or mod wheels in order to make an unnatural signal sound more human.
Programming a theremin vst aax, audio unit plugin isn’t as easy as it sounds, because getting a monophonic signal to portamento properly and decay convincingly well at the same time sounding natural and being easy to control is a bit of a balancing act. However, we feel that we’ve done a good job balancing controllability with ease of use and sound quality, so that the end result is a vst instrument that is easy to play and that sounds good.
Amplitude and vibrato can be controlled individually or together via the pitch and/or mod wheels. portamento can be set to regular or slow, but portamento speed will decrease or increase in regards to the interval that is played (closer notes portamento at a faster rate). Chorus and reverb effects are included and will allow you to create slightly different tones. Purchase includes Windows and Mac VST and AAX versions, as well as a Mac OS X Audio Unit version. The Audio Unit version requires OS X 10.9 (Mavericks) or later.
