Hey thanks.

You can also send the backing track ahead of time a little so that you both hear it at the same time!

Do you mean that you want to mix the inputs from multiple devices ? This is possible - but you do get a little bit of extra latency of course.

It's supposed to refresh the audio devices when you "mouseenter" the select box, so perhaps there's a big there.

Multitrack recording with a bigger buffer would be great.

Good you found the buffer settings. I'm surprised that you found a significant difference though between 2ms and 5ms?
