Midi Problems While using Audio media 3 with Logic audio 4.7

[styfly]

i got a problem with the am3 card when i use logic audio 4.7
the midi data i write (not record) in the matrix editor sound Not Quantized
that means that hihats that are "written"
16/16 sound very very bad
i solved the problem by deleting the preferrence file of logic audio "logic32.prf"
which is in the windows folder
and the midi problem is gone as also the audio setup in logic !!!
so i tried all possible drivers for the card
and still the problem exists
what is there to do to solve this problem
by the way :
this is 100% not a midi interface problem nor a hardware problem with my pc (it's brand new P4 with 256mbram a very good intel motherboard etc.)
please help me solve this problem!!!!!!!
