ROG Splitter-Blend Switching

[mydementia]

Hi guys.
I recently built my own Parallyzer-inspired splitter (thanks the the GGG concept).  I set up the switching using a pair of DPDT's.  The first DPDT selects 'On' or 'Bypass' - the second DPDT selects the 'A' or 'B' loop.  I couldn't figure out a a good switching scheme for 'Both' so I can use the mini-mixer module (currently, it only works as a volume matcher)...then I discovered the ROG Splitter-Blend project (http://www.runoffgroove.com/splitter-blend.html)...

From the schem, it looks like a straightforward mixer with a nice phase reverser (missing from my build).  I perfed one of these up then realized the single input drives BOTH loops (thus, MIXER - stupid me).  I haven't wired up the ROG design, but I want to break the common input so I can have 'A' or 'B' or 'Both'...and I'll probably use a DPDT toggle for 'Bypass'.

When I start jumpering between switch poles - I start getting confused.  Anyone have a thought on how to do this using DPDTs or 3PDTs?

Thanks for looking.
Mike

I've build one and I must say that when you switch in the loops you get a pop.

I highly recommend adding a " panning for fun" (GEOFEX)  part to the schematic and switch through his way of switching for the best results.

Question to ROG: can I post the schematic you build?
