| + | |RmsTC|120|1 to 10000| Controls the time constant (TC) in dB/second that is used for calculating the RMS input value. The time constant determines how rapidly the compressor will respond to input signal level changes, e.g. the “Attack” time.| | ||
| + | |Hold|0|0 to 2000| Controls the time (ms)the envelope maintains the output level before it starts decreasing as the input level decreases| | ||
| + | |Decay(NA for Ext Decay)|10|1 to 10000|Controls the rate at which envelope signal decreases in response to the decrease in the input signal| | ||
