[. . . ] At 100%, the curve bends over smoothly and becomes perfectly flat right before it goes into clipping. LP0 Freq handles the initial lowpass prior to the first distortion stage. With all lowpasses out of the circuit (set to the highest frequency), the sound tends to be too bright and raspy. If you turn off a distortion stage (set to 0%), you should turn off the lowpass filter by setting it to the highest frequency. The amount of boost or cut that the bass shelving filter should apply to the low frequency signals in dB. Every increase of 6 dB approximately doubles the amplitude of the signal. The center frequency of the bass shelving filter in intervals of one semitone. The amount of boost or cut that the treble shelving filter should apply to the high frequency signals in dB. Every increase of 6 dB approximately doubles the amplitude of the signal. Positive values boost the treble signal above the specified frequency. The center frequency of the treble shelving filter in intervals of one semitone. The amount of boost or cut that the mid parametric filter should apply in dB. Every increase of 6 dB approximately doubles the amplitude of the signal. Positive values boost Curve n LP n Freq Bass Gain Bass Freq Treb Gain Treb Freq Mid Gain 165 the signal at the specified frequency. Mid Freq Mid Wid The center frequency of the mid parametric filter in intervals of one semitone. Large values result in a very broad response. 166 305 Subtle Distort Adds small amount of distortion to signal. PAUs: 1 Use Subtle Distort to apply small amounts of distortion to a signal. The distortion characteristic is set with the Curvature and EvenOrders parameters. Increasing Curvature increases the distortion amount while EvenOrders increases the asymmetry of the distortion, adding even distortion harmonics. The distorted signal then is sent through two one-pole lowpass filters and added to the dry input signal. The lowpass filters can reduce any harshness from the raw distortion operation. The Dry In/Out is provided as a utility to audition the distortion signal in the absence of dry signal. [. . . ] Now let's take a look at signal routing specific to Compress 5. 1.

For example, the L->SC1 parameter controls the amount of front left signal amplitude used to control the first side chain. Next, you can select which side chain is used to control the level of each of the signal channels. For example, the R-> parameter sets which side chain will be used to compress the right channel.
