13.7 控制器更改消息

Control change messages are used to change the status of a MIDI parameter. If using an actual MIDI device, these messages can be used to physically control the foot pedals, volume sliders, modulation wheels, and other controls on electronic instruments. Within REAPER, control change messages can simulate this effect when playing back your MIDI data thru a software synthesizer.
控制器更改消息用于更改MIDI参数的状态。如果使用实际的MIDI设备,这些消息可用于实际控制电子乐器上的踏板、音量滑块、调制轮和其他控件。在REAPER中,当通过软件合成器播放MIDI数据时,控制器更改消息可以模拟这种效果。
Controller data is used for various purposes. The different controller data streams are numbered from 0 to 127. Some of these controller numbers are industry standard. For example, controller 7 is generally used to control volume and controller 10 for panning. A control change message has two parts. The first is the control change number, which determines which parameter is to be set. The second is the desired value for that parameter. For example, first, you might send a CC #7 message to specify that you want to adjust volume. Next, you send a value that sets the actual volume level required.
控制器的数据用于各种目的。不同的控制器的数据流,从0到127编号。其中一些控制器编号是行业标准。例如,控制器7通常用于控制音量,控制器10用于声像。一条控制器更改消息有两部分组成。第一个是控制器更改编号,它确定要设置哪个参数。第二个是该参数要求的值。例如,首先,您可以发送CC#7消息以指定要调节音量。接下来,发送一个设置实际所需音量的值。
A control change message can act as either an override (setting the parameter to the exact value specified), or an offset (adjusting the parameter up or down by the amount specified).
控制器更改消息可以用作覆盖(将参数设置为指定的精确值),也可以作为偏移(按指定的量向上或向下调整参数)。
MSB and LSB
MSB和LSB
MSB and LSB stand for Most Significant Byte and Least Significant Byte respectively. MSB control change messages typically act as coarse controls, while LSB messages generally allow fine adjustments. Some control change messages have both MSB and LSB versions. Most MIDI devices that contain sounds/patches respond to both Bank Select MSB and LSB control change messages.
MSB和LSB分别代表最高有效字节和最低有效字节。MSB控制器更改消息通常充当粗略控制,而LSB消息通常允许微调。某些控制器更改消息同时具有MSB和LSB版本。大多数包含声音/音色的MIDI设备,同时响应音色库选择MSB和LSB控制器更改消息。
Some of the more commonly used cc parameters are listed below. Don’t worry if you don’t understand them all. You should consult your MIDI device’s documentation for more details.
下面列出了一些比较常用的cc参数。如果你没有全部听懂,也不要担心。您应该查阅MIDI设备的文档以了解更多详细信息。
Parameter Description
参数    说明
Bank Select MSB
音色库选择MSB
Bank Select LSB
音色库选择LSB
Many MIDI devices offer a total of more than 128 instruments, in which case these instruments are grouped into banks. Thus, depending on the device, a full program change message might consist of five parts - cc #0 (Bank Select), followed by the Sound Bank MSB value, then cc #32 (Bank Select LSB) followed by the Sound Bank LSB value, then finally the Program Change number. Program change numbers are discussed in more detail in the sub sections that follow after this one.
许多MIDI设备总共提供超过128种乐器,在这种情况下,音色库选择LSB将这些乐器分组为音色库。因此,根据设备的不同,完整的音色更改消息可能由五个部分组成——CC#0(音色库选择),接着是音色库MSB值,然后是CC#32(音色库选择LSB),接着是音色库LSB值,最后是音色更改编号。音色更改编号,将在此之后的一节中进行更详细的讨论。
Velocity
力度:
The measure of the speed with which a key on a keyboard is pressed.
按下键盘按键的力度大小。
A lane is also available for Note Off Velocity.
子轨也可用于“音符关闭力度”。
Mod
调制轮
Wheel This can add vibrato or other changes to a sound.
可以给声音增加颤音或其他变化。
Breath
呼吸
Varies from 0 (no force) up to 127 (high force).
范围从0(无力)到127(大力)。
Portamento
滑音
Determines the smoothness of the glide from note to note
确定音符之间滑动的平滑度
Balance
平衡
Typically used to adjust the volume of stereo parts without affecting the panning.
通常用于调整立体声各部分的音量,而不影响声像。
Expression
表情
Used to create relative volume changes.
用于创建相对音量变化。
Sound Timbre
音色:
The property of a sound that gives it its unique “color”.
声音的属性,赋予它独特的“颜色”。
Sound Release
声音释放
Determines how long it takes for a sound to fade out.
确定声音淡出需要多长时间。
Sound Attack
声音启动
Controls how long it takes for a sound to fade in.
控制声音淡入的时间。
Sound Brightness
声音亮度
This adjusts a sound’s filter cutoff, allowing you to create filter “sweeps”.
此选项可调整声音的滤波器截止,允许您创建滤波“扫频”。
