There’s a time lag
from when you
play the keyboard
until your software
sound generator
produces sound
Have you lowered (decreased) the audio buer
size of your software sound generator?
Have you lowered (decreased) the buer size
for your sound card?
A software sound generator produces sound
using your computer’s sound card. Before the
sound from the software sound generator is
actually heard from the sound card as sound,
there will be a time lag referred to as “latency.”
Regardless of the combination of sound
generator and sound card you use, there will
always be some latency. Usually, however,
the latency can be kept to an acceptable
amount by using the right combination of
sound generator and card, and by making the
appropriate settings.
For details on how to make these settings,
refer to the owner’s manuals for your software
and sound card.
