推荐答案
他们没有.商业音乐不会以任何系统的方式使用微音，因此没有大量的商业软件工具可以帮助实现这一目的.
MIDI本身几乎没有微调性的概念，它最初是为键盘演奏者演奏的同等回响的音乐而设计的，直到今天仍然如此.微调永远是MIDI的骇客……
They don''t. Commercial music doesn''t use microtones in any systematic way, so there are no significant amount of commercial software tools that helps with that.
MIDI itself is pretty much void of the concept of microtonality, it was originally designed for equal tempered music played by keyboard players and has remained so to this day. Microtunings will always be hacks with MIDI…
我知道这种黑客攻击只有一个主意，但是我从未尝试过使用它.这是关于使用 音高弯曲 的一种方法，它可以使用键盘上的"弯曲轮"来模仿标准"半音.能够像吉他一样弯曲的乐器.
查看MIDI规格:
http://www.midi.org/techspecs/midimessages.php [ ^ ].
看来您可以设置音高弯曲灵敏度来应用50美分的弯曲，这是引号音(1美分是音高比，对应于半音的均等气质，分为100个步长，每个步长为1美分，按对数刻度).
但是，从另一个来源来看，弯曲消息的真实解释似乎取决于合成器. 弯音消息的最大值仅表示弯度尽可能高".即使对于欧洲音乐来说，那也将是一场灾难，所以我简直不敢相信，但请参阅 http://www.srm .com/qtma/davidsmidispec.html [ ^ ].
现在，我从未尝试查看MIDI API来确定是否可以使用弯曲以及弯曲的结果.尝试做.如果您将发现的情况写给我们，那将是非常好的.
如果您能给我一些有关阿拉伯微调音乐样本和/或其他相关文献的链接，我个人将不胜感激.我以前只听一点点，非常有兴趣.
I know only one idea for such a hack, but I never tried to use it. This is about using pitch bend, something which allows to deviate from a "standard" semitone using a "bend wheel" on a keyboard to imitate instruments capable of bending like a guitar.
Look at the MIDI specs:
http://www.midi.org/techspecs/midimessages.php[^].
It looks like you can setup pitch bend sensitivity to apply bending of 50 cents which is a quoter-tone (one cent is a pitch ratio corresponding to equal temperament of semitone divided into 100 steps, 1 cent each, on logarithmic scale).
However, from the other source, it looks like a real interpretation of a bend message depends on the synthesizer; a maximum value of a Pitch Bend Message of 16383 only says "bend as high as possible". That would so much of a disaster even for European music, so I hardly can believe that, but see http://www.srm.com/qtma/davidsmidispec.html[^].
Now, I never tried to look at the MIDI API to figure if it''s possible to use bending and what''s the result of it. Try to do it. It would be very nice if you write us about your findings.
I personally would be really grateful if you could give me some links to Arabic microtonal music samples and/or other related literature. I used to listen just a tiny bit, very interested.
