i think i remember a similar problem
in my case i have 2 soundcard: via-integrated and m-audio-delta1010
similar (or same) latency problem ocured when i was using midi from 
"m-audio" and audio engine on my "via".
so im using always my m-audio card for everything (anyway better;)
i think that it may be the problem of cheap soundcard, or the drivers 
for it. maybe you can try some stuff like asio4all and try to run it 
with this driver, maybe try with a better quality soundcard...
my only recommendation is to try all possibilities with your audio-midi 
connections :)
hope this brings u somwhere
