sfz definition filter eg

I try to figure out how to create sfz file with filter envelope. I use sample from Rapture LE library: Rapture LE > Multisamples, sample named "015 - saw 8080.wav".
In sfz definition file I put the following text:

<region>
pitch_keycenter=36
sample=015 - saw 8080.wav

fil_type=lpf_2p
cutoff=1000
fileg_attack=1
fileg_decay=1
fileg_sustain=0

I load this file into sfz player, sample is playng OK, but filter EG's not working - no changes in cutoff frequency.

What I do wrong?

    Vovchik,

    You know about the specification doc for SFZ, right? It's available under Support for 3rd party developers from this website.

    Yes, I know about the specification doc for SFZ, but I still don't understand why filter EG doesn't work in my script. Is it wrong numbers or opcodes? I tryed fileg_depth, fileg_start etc... in vain.

    Well, it turned out "cutoff" has to be set at very low number, even zero, to hear filter EG work.

    Now there is one more thing I can't understand.

    <region>
    pitch_keycenter=36
    sample=015 - saw 8080.wav
    cutoff=0
    fileg_depth=12000
    fileg_decay=1
    fileg_sustain=0

    If cutoff and sustain both set to 0, why I still can hear some sound after decay time?
