We suspect your latency problem is due to the audio driver settings in the
PC. Are you able to change settings via finale? Depending on your soundcard
type, it may have an ASIO driver that you can select to use and this
normally allows you to select the audio 'buffer' size and this determines
the latency .The smaller the buffer size is, the lower the latency, however
please note that if you set the latency too low for your computer you may
run into problems with audio clicks and pops appearing if the computer is
not able to run at extremely low latency (this normally depends on the
processing power of the computer).
We recommend using asio4all (http://www.asio4all.com/
). This provides a very
good interface to your soundcard drivers and lets you adjust the buffer
sizes to change latency.
