This is a problem everyone has on all operating systems.  It's called
"latency".  If you're on Linux, you solve that by using JACK instead of
ALSA or PulseAudio.  To bring latency down even further, you then either
use an RT kernel (overkill) or a standard kernel patched with BFS

If you're on Windows, you need to install an ASIO driver for your sound
card.  If there isn't one, you can use the asio4all driver (google it.)
 But I don't know if LMMS supports ASIO.  If not, you will have to live
with the latency and there's nothing you can do short of using something
other than LMMS.
