Latency advice anybody??

[rockabilly1955]

ok, maybe somebody helping newbies can give me some tips..........I use a presonus firebox as my interface along with Magix audio studio as my software. Everything works fine when i am overdubbing to a previously recorded track. There is no audible latency as i am recording my guitar part and seems to be in sync with the first track. However, as i record more instruments, even though it sound good and in sync with the tracks while recording, when i play back the tracks all together it seems to be a off and not in sync. Any ideas on this issue?? Could it happen because one of uses headphones while recording, while the other intruments were maybe recorded just by listening to the playback through monitors, which would throw our timing off by some millisecs?? what are the best methods/settings to do latency free overdubbs?? thanks

While I apologize in advance for not answering your question, I will add that you should post this in the computer forum. There are guys who deal with latency all the time in there and can answer that. I record to a digital multitracker, so latency isn't a problem. Sorry I couldn't be more help.
