问题 单项选择题

通用MIDI标准的音乐设备支持16个通道,最多可以同时演奏出(1),多台MIDI乐器之间通过(2)方式进行连接。 空白(2)处应选择()

A.菊花链

B.共享总线

C.环形

D.星形

答案

参考答案:A

解析:

本题考查MIDI标准的基本内容。

MIDI文件中含有几种乐器的组合音乐,各种乐器由于音色不同具有不同的波形。通用MIDI标准中单个物理MIDI通道可为16个逻辑通道提供数据,每个通道可以指定一种乐器。对应16种逻辑的合成器,即最多可以同时演奏16种音色。

MIDI设备包含三种MIDI端口:

·MIDI-IN(输入),用来接收从其他MIDI设备发过来的消息;

·MIDI-OUT(输出),用来发送本设备产生的原始MIDI消息;

·MIDI-THRU(转发),用来在MIDI设备之间进行消息转发。

MIDI设备至少需具备一种端口,可同时具有三种端口或两种端口。在一个MIDI设备上的MIDI-IN端口接收到的信息可以通过MIDI-THRU端口输出到另外一个MIDI设备去,这样多台MIDI设备标准连接方式即一台串一台的菊花链方式。

Crosstalk(相声),a traditional form of comic storytelling,is making a comeback in China’s tea houses and theaters.

Audiences can laugh the night away every Saturday at the Qianxiangyi Teahouse in Tianjin,entertained by the apprentices(学徒)of Hou Baolin,Ma Sanli or Yin Shoushan—all leading crosstalk artists of years past—for only 20 yuan($2.40).

The success in Tianjin has also caused the rejuvenation(复活) of crosstalk in Beijing and other places.

Although the art form originated in Beijing in the Qing Dynasty(1644-1911),Tianjin became a place where rising stars formed their styles and new pieces were tried out.The city was well—known nationwide for the quality of its crosstalk performances.

Known in Chinese as xiangsheng(1iterally,“face and voice”),crosstalk was the predominant(支配的)form of comedy throughout most of the 20th century.In the old days in Tianjin and elsewhere,temple fairs and markets were the main places for crosstalkers to perform,although they occasionally also appeared in teahouses or theaters.

Crosstalk pieces draw on every aspect of Chinese culture,from history and folk tales to social issues of the time.Although there’re hundreds of traditional pieces,they’re constantly rewritten to suit the times and the audience, while new works are written as well.It’s one of the features that have made crosstalk a

public art form throughout its history.

“Crosstalk was in the doldrums(萎靡不振)with competition from other art forms,especially TV,”said Wang Xiaochun,headmaster of the Northern Storytelling Arts School of China(NSAS).“But it has regained its status with crosstalk fans,especially young people,growing aware of its rare qualities.”

“More and more students are coming to NSAS to study crosstalk,including some girl students,”said Wang, “They’re sure that crosstalk will have a strong market.”
