| Effect (P1) | how much the operator effects the outcome |
| Bands | Just how many bands should SFX use. Less Bands means less math, but you lose out on accuracy. |
| Steps | SFX does a transformation every sample-values. Lower values mean better quallity butlonger calculation. Steps can no be bigger than the half of the number of bands. |
| Window (W1) | what windowfunction to use |
| Ampf | final amplification |
| EAmpf | amplification for the envelopefollower |
| EFCoef | factor for the inertia of the envelope follower. Meaningful values are rangingfrom 0.8 to 1.0. |
| Src2Inv | Should I flip the envelope for the modulator (src2) (loud becomes quiet and reversed). |
