help solving bug in my instrument script

[claud9]

hope somebody can help me.
I have finish to script my instrument, everything works except for 4 parameters that even if I save the .nki instrument they always come back in -36st position for the pitch knobs and 100% position for the two LFO amount knobs.
The position of all other knobs (volume, pan, other two pitch knobs) are correctly saved with the instrument except for these 4 parameters.
What could be??
The really strange thing is that I have 4 pitch control (one for very layer), and two works perfectly, the other two come always back at the -36st position!

Thanks in advance for any help and seggestion!
