Levelizer can send a copy of it's input to A or B that may be used to key subsequent Leveliers

Multitrack has it's own virtual buffer which can pass a return's mix to the following return channel (instead of an output bus).
The next puzzle to figure out:
If 2 is receiving VBs from 1, is it also mixed with audio sent from input channel Aux2?
...or is 1's input (or output) replicated on 2's input?
Not sure what you mean by "each help."
Buffers are there if you need them, otherwise, they don't do anything.
There are two available between Levelizer instances: A and B. You determine which to use by the Key and Send selections you make in a Levelizer instance. Yeah, you sound like you get that.
As for the multitrack buffers...

Not sure I follow you, here. As I understand it, the multitrack buffers are just clones of each channel's input signal (not sure from where it's tapped, though) available to other channels' compressor module key inputs as well as plugins coded to receive them as key inputs (Ã* la the Levelizer). The returns only come into play, here, if you've patched a Levelizer into one of them. And the multitrack buffers don't operate between returns, they operate between an input channel and wherever you patch a Levelizer, which, of course, can be a return.
>>If 2 is receiving VBs from 1, is it also mixed with audio sent from input channel Aux2?<<
Not sure what you're asking, here.
Realize that these buffer "signals" are completely separate from any audio you will ever hear. These "signals" are hidden in the background, only acting on Levelizer key inputs, which impact the way the module operates on the audio that passes through it, but which don't mix with the audio you're processing.
So, in your case, the buffer signal is sent from Levelizer 1 on Return 1 via buffer A. It's received by Levelizer 2 on Return 2 via buffer A. It's EQ'd according to the high- and low-pass setting you may have made, and thusly the gate and/or compressor sections of that Levelizer react to it, impacting the audio that came from Aux 2, which is then sent on to an output bus.
So, the only time the audio you hear and the key signal you desire ever "touch" is when the latter is split/cloned from the former at the input to the Levelizer (for buffer A and B) or at the tap point for a channel strip (for the channel buffers).
FWIW, regarding the channel compressors, SAWStudio's help says "The Key Buffer contains the source data used to trigger the Gate and Compressor into action. This data is available from the channel source data itself (Self), or from any other channel source data (1 - 72). " That sounds to me like the tap is of the virgin signal entering the channel strip, before any processing at all.
Does any of this make any sense?
