What does the Range knob do?
The Range knob affects both the way attacks sound and also limits the total depth of compression to give a more natural sound. The range set at full is good for limiting applications or if you want loads of pumping when using an external sidechain signal of a kick drum on a synth. Try over compressing a sound with a severe setting with the Range knob on full, then reduce the Range to around -20 or -10 dB and listen to the difference.
