dspLoad 3.50/6.60/3.50
Ratio: relation value (input level:output[compressed] level).
(Ratio 1:1=no effect, inf:1=max effect.)

dspLoad 3.50/6.60/3.50
a special-purpose compressor. The level  of the SideChain (SCI) signal remains constant, while the signal fed into the module (In) is attenuated according to level variations of the sideChain signal. (Ratio: 1:1=no effect, inf:1=max effect.)

dspLoad 8.40/5.10/5.10
the module attenuates the lower passages while leaving the louder ones unaffected.(Ratio: 1:1=no effect, 10:1=max effect.)

dspLoad 3.50/6.60/3.50
Similiar to Compressor. Attack and Release value should be greater than zero to avoid distorted sound.
(Ratio: 1:1=no effect,  inf:1=max effect.)

dspLoad 3.40/6.60/3.30
only input signals with amplitude higher than threshold level pass through. Floor: ”dry” (not gated) sound. 
(Thresh -96, Floor 0=no effect; Thresh 0, Floor -96=max effect)

general controls:
Attack -the time it takes the module begins to react after the threshold has been crossed. Release -how quickly the module stops processing after the threshold level has been crossed. Thresh - the level at which the module is beginning to process the signal.
