For Mac OS X audio software
For audio software running under Mac OS X, go to
the menu item or preference where you choose the
audio device (Core Audio driver) you wish to use,
and then select the LP32 by name.
For Windows audio software
For audio software running under Windows, go to
the menu item or preference where you choose the
ASIO driver you wish to use, and then choose
MOTU Pro Audio. If your host audio software
doesn’t support ASIO, choose the MOTU Pro Audio
Wave d r i ve r i nste a d .

information.
REDUCING MONITORING LATENCY
Monitoring latency is a slight delay caused by
running an input signal through your host audio
software and back out. For example, you might
hear it when you drive a live guitar input signal
through an amp modeling plug-in running in your
audio sequencer.
This delay is caused by the amount of time it takes
for audio to make the entire round trip through
your computer, from when it first enters an input
on the LP32, passes through the interface hardware
into the computer, through your host audio
software, and then back out to an output.
