midi input lags...

hi i’m a newbie here…

i’m using cubase 5 LE on my windows XP sp3 system…

when i’m trying to record miditrack associated to external synth (roland juno-d)…

(lot of sustain pedal and piano sounds)

the midi thru sounds delayed and lags…that i cannot play live …

when i touch the keyboard , it sounds after about 0.5seconds …

and sometimes its not lagging and suddely lags again…and again…

my audio card is m-audio delta 196 and midi input/output is on it …

i have sonar 8 pro on the same system…

and the midi does not lags on sonar…

please help ??!!

and i’ve already tried “use system time stamp” but no luck …
