DIVA and MPE ch pressure

[23fx23]

Hi, I have problem to understand how diva handles ie pressure to volume in MPE
when i test in ableton live, enabled all MPE stuff, checked got nice incoming presure values range,
then on diva set AMP mod to pressure:
I do hear little variations that reflect pressure, however they are very, very subbtle,
mean like would be 10% of what other synths would do for fullrange,
while mod knob is cranked up.. (and abbleton does show values ranging 0-127)
I there something special im missing to setup here?
(checked ie ableton build in wavtable synth, or eaganmatrix exteranl hardware gear, to make sure it's not input problems, both behave as i expect, so i think it's a diva setting problem somewhere)
