Exactly like that. @modular01
And I guess I could use 2x Attenuators per Stereo Pair to adjust, but isn't there something called Panning Law https://samplecraze.com/tutorials/the-pan-law/ and the way Panning should work versus just attenuating a split Stereo signal.
From what I can see, there's not really a cost effective module out there to handle the panning.
Though if someone made a 4-6hp module with 3-4 Stereo Panning channels it would be pretty handy.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
