hello, i am running protracks plus on windows xp with a soundblaster sound card. i am running an electric guitar thru a digitech rack processor into the card using a splitter combining two quarter inch lines into one eighth inch. the problem i am having is, when i arm the track for recording, there is a delay. you hear the guitar instantly and then again, louder, about a half second later. it only happens when the track is armed to record. any ideas? thanks in advance.
