Reaper: ReaDynamicEq

I've made a preset/fx-chain for a Dynamic Equalizer in Reaper
-ReaDynamicEq.

What it is:
A Dynamic equalizer are used instead of an ordinary Eq when the chosen frequency needs to be tamed only at certain levels. So, it's sometimes less Eq, sometimes more.

Download here:

ReaDynamicEq -1band
ReaDynamicEq -3band

Download and installation:

• Download the above files (save link as)
• Copy to your "FxChains" -folder
  (Example: "C:\Documents and Settings\YourName\Application Data\REAPER\FXChains\Dynamic Eq\")

Now, in Reaper, on desired track:
(This part is explained for the 1Band-version)

• Right-click fx-button, navigate "add Fx Chain > Dynamic Eq > ... "

This opens the Track fx Window. You'll see two ReaEqs, ignore the first (it operates in slave-modus).

To adjust settings.
On the second ReaEq:

• Frequenzy/Bandwidth: Adjust as desired
• Gain: Gain works only in slave-modus here, see below..

Click on Gain, then "Param > Parameter Modulation". This will open the "Parameter Modulation for ReaEq"

• .. baseline value: Adjust fixed band-gain here
• Attack/Release: Adjust to taste
• Min volume: Sets the Threshold (low) for when the gain-reduction should be applied
• Max volume: Sets the Threshold (high) for when max gain-adjustment is reached
• Strength: Sets the amount of gain-reduction (20% typically gives 4.4db reduction above Thres-high)

Tips:

1. Set Min and Max volume to zero and adjust Strength to get a clear view of how much gain-reduction a certain Strength-setting gives. 
2. If you're used to tweaking with added gain, do that with ".. baseline value".
3. Leave Max Volume at 0db for a more normal mode, or adjust downwards to give the compressor a more range-character. Adjust Strength accordingly.
4. Add bands in the Eq to combine the dynamic band with normal EQ-bands.
5. If you want to use shelving bands, you'll have to set the corresponding slave eq-band to "high/low-pass"

Enjoy!
