Trying to wrap my brain around software Aux buses and FX buses.
( busses?)

The name and the application. Actually, they're all Auxiliary busses,
some used to send a signal to an effect, other used to send a signal
to something else.

Typically effects sends are post-fader so the signal level going to
the effect changes in proportion to the level of the unprocessed
signal in the mix, so on "user friendly" mixers, post-fader busses are
often labeled "Effects."

A stage or headphone monitor mix is often different from the main mix,
so those busses are fed pre-fader. Usually if there's an "Effect" bus
on a mixer, there will be a corresponding "Monitor" bus for pre-fader
sends. On a general purpose mixer, you'll find then all called "Aux."
There may be a switch to select whether their associated busses are
pre- or post-fader or some maybe hard-wired one way or the other.

Also, can someone
explain or point to a good resource to explain 1) What send vs return
does and 2) the pre/post issue on an Aux bus?

Also, not clear on why there's an individual track Aux bus control as
well as a separate Aux bus.

http://mackie.com/support/compactmixer/index.html is a good
explanation of what's what in a mixer. You can apply what you learn to
either hardware or software mixing.
