19.9 Parameter Modulation Under Parameter Control
19.9 参数控制控制参数调制

By linking parameters you can use dynamic changes in one FX parameter to directly control another. In this next example you will do just this, linking a track's EQ gain with its compressor threshold, so that whenever the compression threshold is raised a little more warmth is automatically added to the track.
通过链接参数,可以使用一个FX参数的实时更改,来直接控制另一个参数。在下一个示例中,您将执行此操作,将轨道的EQ增益与其压缩器阈值相关联,这样每当压缩阈值提高时,就会自动向轨道添加更多的温暖感。
1. Open the file All Through the Night MOD1A and save it as All Through the Night MOD1B.
1. 打开文件All Through the Night MOD1A,并将其另存为All Through the Night MOD1B。
2. In the vocal FX chain, add an instance of ReaEQ (after ReaComp). Select Band 2. Set the Frequency to about 180 Hz, the bandwidth to about 2.00 octave and the Gain to 0.0 dB.
2.在vocal FX链中,添加一个ReaEQ实例(在ReaComp的后面)。选择频段2。将频点设置为180赫兹左右,带宽设置为2.00倍频程,增益设置为0.0分贝。
3. With the ReaEQ window open, click on the Band 2 Gain control, then the Param button, then Parameter modulation/MIDI link to open the Parameter Modulation window. Select the option Link from MIDI or FX parameter.
3.在ReaEQ窗口打开的情况下,单击频段2的增益控件,然后单击“参数”按钮,然后单击“参数调制/MIDI链接”以打开参数调制窗口。选择选项“链接MIDI或FX参数”。
4. Click on the large button below the Link from MIDI or FX parameter option and choose ReaComp then Thresh (as shown here).
4.点击“链接MIDI或FX参数”选项下方的那个大按钮,然后选择ReaComp,然后选择“Thresh(阈值)”(如图所示)。
5. Before playing the song, adjust the baseline value fader to restore the Gain on Band 2 in ReaEQ to 0 dB.
5.在播放歌曲之前,调整基线值推子,将ReaEQ中频段2的增益恢复到0dB。
6. Set the Offset fader to 10% and the Scale to +100% (see notes below).
6.将“偏移”推子设置为10%,将“比例”设置为+100%,请参见下面的注释。
7. Play the song and save the file.
7.播放歌曲并保存文件。
In the examples at 19. 5 and 19. 6 parameter modulation was used to create quite a dramatic effect. In the examples at 19. 7 and 19. 9 the effect is more subtle.
在19.5和19.6的例子中,使用参数调制来产生相当戏剧性的效果。在19.7和19.9的例子中,效果更加微妙。
The two controls Offset and Scale can be used to control the extent to which the controlling parameter (in this example the compressor's threshold) modifies the controlled parameter (in this case the EQ band gain).
“偏移”和“比例”这两个控件,可用来控制控制参数修改受控参数的程度。(在本例中,控制参数为压缩器的阈值,受控参数为均衡器的频段增益)
The Offset fader increase (to the right) or decreases (to the left) by a specified percentage the value of the parameter being modified The Scale fader ranges from -100% to +100%. At -100% the relationship between the controlling parameter (threshold) and the controlled parameter (EQ band 2 gain) will be 100% negative: the EQ gain will be lowered exactly as the threshold is raised. At +100% the relationship will be 100% positive and the opposite will occur.
“偏移”推子,按指定的百分比增加或减小要修改的参数值,(向右是增加,向左是减小)。“比例”推子的范围,从-100%到+100%。在-100%时,控制参数阈值和受控参数均衡器频段2增益,之间的关系将为100%负: 均衡器增益将恰好随着阈值的提高而降低。在+100%时,关系将是100%正,反之亦然。
If you just want to control the whole range of the target parameter then just set the Baseline [B] slider to the left (0%), Offset [O] to 0% and Scale [S] to 100%.
如果您只想控制目标参数的整个范围,则只需将基线[B]推子设置为左侧(0%),将偏移[O]设置为0%,并将比例[S]设置为100%。
To control just part of the target parameter's range, first of all, work out what that part is in % terms. For example, consider an EQ gain band with a range of -24 dB to +24 dB and you wish to control the value between -12dB and +12dB. The percentage range is accordingly from 25% to 75%.
要只控制目标参数范围的一部分,首先要计算出该部分的百分比。例如,假设均衡器增益范围为-24分贝至+24分贝,您希望将该值控制在-12分贝至+12分贝之间。因此,百分比的范围是,从25%到75%。
Make sure that you can see the target parameter on the FX's GUI and the Parameter Modulation window and set the Scale [S] value temporarily to 0%. Drag the Baseline [B] slider 25% to the right and you should see the target parameter change to -12dB. Now set the Scale to 50% (that is 75% - 25%). That's it. There is no need to adjust the Offset. In fact, you won't need the Offset often. It can be used to slide the range up or down. Please note that the actual change is determined by the Offset % multiplied by the Scale %. Let's look at [B] = 50%, [O] = 0% and [S] = 25%, this results in a range of 50% to 75%. If we now set [O] to -40% the range changes to 40% to 65% the change is [O] x [S], that is -40% X 25% = -10%).
确保您可以在FX的GUI,和参数调制窗口上看到目标参数,将比例[S]值临时设置为0%。将基线[B]推子向右拖动25%,您应该会看到目标参数更改为-12dB。现在将比例设置为50%,即从75%到25%。就这样。没有必要调整偏移。事实上,您不会经常需要偏移。它可以用来向上或向下滑动范围。请注意,实际变化是由偏移量%乘以比例%来确定的。让我们看看,[B]=50%,[O]=0%,[S]=25%,结果是50%到75%。如果我们现在将[O]设置为-40%,则范围将更改为40%到65%。换成[O]×[S],即-40%×25%=-10%。
