It seems like something else is making the issue. It shows the response of U1, which I copy to the sub-channels, so part of the sub-filter-routing is simulated.
My setup is:
Fronts 2-way active
Center
Surrounds (left side, right side, center rear)
4 individual subs (Sometimes MSO, sometimes my own parameters)

ignoring assorted delays, looks like you currently
* sum L/R/C/SW into U1 then copy it to 4 separate output channels & filter individually
* sum RL/RR together and route to RR
* C is a single way (crossed to the sub with an LR4 120)
* LR is a 2 way (crossed to sub with LR4 100 then a symmetric LR4 at 250)
a few Qs
* I wonder why RL/RR are summed and not crossed to the sub?
* you don't see to handle the adjustment between LFE and main channels, is there no LFE channel?
in any case, to implement the above, I think I would
* add a XO filter to deal with LRC/SW (probably leave RL/RR as passthrough in that filter), group LR as one in that filter and set as a 3 way, leave C as is and mark as a 2 way, update routing matrix to ensure the routing the LRC/LFE channels are summed into the SW output, you can happily include the extra 3 SW outputs here & also invert the subs (and channel specific delays/gain adjustments can be added here too)
(NB: I don't allow overwriting input channels in the routing matrix as it makes the subsequent logic really way more complicated for little benefit)
* add mix operations for RL/RR summation
* add move operations if you need to keep your existing output channel mappings
(NB: I don't currently support the reorder channels option as it only supports 8 channel output at present so this is more tedious than it should be)
* add a PEQ block for SW output for the per sub filtering
* add a GEQ filter for the shared peak filter applied to the lower way in the LR
mattkhan:
definitely a couple of bugs in the latest impl of the XO filter in how it generates mix filters for your particular setup (combining RL/RR, cloning the SW to multiple sub outputs) so I'll have to look at those, nice test case for me as I hadn't thought of some of these as things to try
I also assume the .1 is an LFE channel so force the -10dB offset but you don't do that so I guess it really isn't an LFE channel?

Dude this is sick.
Thank you so much. I'll probably play around with it later this weekend. I really appreciate you including the source, especially in light of how dumb virus scanners can be with false positives in these situations. It's just an illusion of security (unless you actually go and build it yourself) but it's a good show of faith <3
Honestly, checking out the screenshots here, the JRiver guys should integrate this workflow into the main software. As someone who's intimately familiar with JRiver's DSP functionality and has been using it well over a decade, this makes a ton of sense, especially for new users. It's a solid alternative paradigm.

Is this cross-platform?

yes
NB: I don't have a mac myself so am unable to test it directly, I'm told it works fine though
