If you haven't already done so, read this section of the installation guide:

   http://www.circularlabs.com/doc/installation.htm#Tuning Latency

Assuming you are using Windows, if you are using the built-in sound card

you will be using an "MME" driver which has very high latency.  It is possible

for Mobius to compensate for this so that your overdubs will line up but

you have to enter the right values into the latency fields in the

Audio Devices window.  Sometimes the driver is able to tell us what

the latency is, other times it can't and we have to enter it manually.

This is explained in the manual.

If you use a pro audio interface it will come with ASIO drivers that

have very low latency.  Often people don't even bother tuning latency

compensation since it is so slight that it is hard to hear even if it

is off by a few milliseconds.

As an alternative to buying a pro interface you could also try

ASIO4ALL which will give the built-in sound card an ASIO driver.  I have

had success with this, but if you're serious about sound quality you

should still consider an external interface.

I'm not sure what this was referring to, but you can certainly tune

latency compesnation for exact alignment of overdubs and once set it

won't drift unless you are also changing your physical location

relative to your monitor speakers.
