19.5 使用音频控制进行参数调制

In this first example, we will insert a plug-in such as chorus into a track’s FX chain, then use that track’s audiosignal to control the way that plug-in behaves.
在第一个示例中,我们向轨道的FX链中插入一个插件,如合唱,然后使用该轨道的音频信号来控制插件的行为方式。

Example
示例
1.  Open the file All Through The Night and save it as All Through The Night MOD1.
1.打开文件All Through The Night,并将其另存为All Through The Night MOD1。
2.  Adjust track faders to get a reasonable mix.
2.调整轨道推子,以获得合理的组合。
This could be Volume at -0.5 db, center, Guitar Body at 0 db, 55% left, Guitar Neck at 0 dB, 63% right, and Bouzouki at -4 dB, 15% left.
这可以是音量-0.5分贝,中间；Guitar Body0分贝,55%左；Guitar Body0分贝,63%右；Neck-4dB,15%左。
3.  Solo the Bouzouki track. While working thru this example, this is the only track that will be needed.
3.独奏Bouzouki轨道。在完成此示例的过程中,这是唯一需要的轨道。
4.  Insert the JS: Delay/delay_chorus plug-in into this track’s FX chain, and set the various parameters as shown here.
4.在该轨道的fx链中,插入js的Delay/Delay_Challus插件,设置各种参数,如下图所示。
5.  Click on the Output Wet (Chorus) (dB) rotary in this plug-in.
5.点击此插件中的Output Wet(Chorus)(DB)(输出湿声合唱)旋钮。
Notice that currently this is set at 0.0.
请注意,当前该值设置为0.0。
6.  Click on the Param button, then choose Parameter Modulation/MIDI link from the menu.
6.单击“参数按钮”,然后从菜单中选择“参数调制/MIDI链接”。
This will open a parameter modulation window for the output wet parameter.
这将打开输出湿声参数的参数调制窗口。
Enable the option Audio control signal and select as the Track audio channels 1 + 2.
启用“音频控制信号”选项,并选择轨道音频通道为1+2。
Play the track.
播放轨道。
7.  The wet rotary on the plug-in was initially at 100%, as shown here.
7.插件上的湿声旋钮最初为100%,如下所示。
However, as you adjust the baseline fader (in the PM window) while the track is playing, the wet value in the Chorus window (shown to the immediate right of the 2 in 2 out button) is also adjusted.
但是,当您在播放轨道时,在PM窗口中调整基线滑块时,在合唱窗口中,显示在“2进2出按钮”的正右侧的湿声值,也会进行调整。
   Leave it with a wet mix level of about 50%.
让它保持50%左右的湿声混合电平。
8.  Set the various items in the Parameter Modulation  window as shown below and play the track.
8.设置参数调制窗口中的各项,如下图所示,播放轨道。
You should notice the wet mix element of the chorus being faded down for louder notes and passages and up for quieter notes and passages.
你应该注意到,合唱的湿声混音成分,在音符和段落较响亮时逐渐减弱,而在音符和段落较安静时逐渐增强。
9.  Now experiment! You should find that:
9.现在开始实验吧!您会发现:
    ?  Moving the Attack and Release faders left will result in the wet mix chorus fader movements becoming more jerky.
?向左移动启动和释放的滑块,将导致湿声混合合唱的旋钮,动作变得更加急转直下。
Moving them right should make them smoother.
将它们向右移动,应该会使它们更平滑。
    ?  Moving the Strength fader (negative) to the right will cause the wet mix chorus fader to be faded down for louder notes and down up quieter ones.
向右移动强度滑块到负值,将导致湿声混合合唱旋钮,往上推时,音符较响亮,而往下拉时,较安静的音符。
Selecting positive reverses this.
选择为正值时,会反转这个操作。
    ?  Moving the Min Volume fader left will lower the threshold at which the parameter modulation is applied. Moving it right will raise the threshold.
向左移动最小音量滑块,将降低应用参数调制的阈值。向右移动将提高阈值。
10. When you have finished experimenting, adjust the settings to those shown here.
10.完成实验后,将设置调整为此处显示的设置。
  11. This instrument becomes louder as the song progresses.
11.随着歌曲的进行,这件乐器的声音变得更大了。
Play it, with the Bouzouki unsoloed.
加入未独奏的Bouzouki播放它。
By the end, there is less chorus being applied to the bouzouki.
到了最后,bouzouki的合唱变得更少了。
   12. Now play the song again.
12.现在再播放一遍这首歌。
Drag hold of the handle on the graph, and use your mouse to drag it to the lower right position.
按住曲线图上的手柄,然后使用鼠标将其拖动到右下角位置。
Notice that the movements of the wet mix fader now become more modest.
请注意,湿声混合旋钮的移动,现在变得更加温和。
   13. Now drag hold of the handle on the graph, and use your mouse to drag it towards the top left corner of the graph (as shown below).
13.现在拖动曲线图上的手柄,并使用鼠标将其拖动到曲线图的左上角(如下图所示)。
Notice that the movements of the wet mix rotary now become sharper and the wet mix level reaches lower values.
请注意,湿声混和旋钮的运动,现在变得更加尖锐,湿声混和电平降到较低的值。
   14. Restore the graph to its earlier position (shown at step 10) when you have finished.
14.完成后,将曲线图恢复到其较早位置(如步骤10所示)。
Save the file.
保存文件。
