Hello,
Here i the situation. I dont want to use the pedal inputs on my p12 because im using them to control the filters on both layer a (pedal 1) and layer b (pedal 2), just so its clear that i cant use them. I want to use a volume pedal after main output A to control the volume of layer A, and i want to use another volume pedal after main output B to control the volume of layer B. From these two volume pedals i want to sum both signals into a third volume pedal where i use two mono splitters to sum "Layer A and B Left" into the third volume pedals Left input, and sum "Layer A and B Right" into the third volume pedals Right input. From there on i want to send the summed signal into a "Passive mixer" (which is the place where i sum the signals from "layer A and B P12", "Ob6" and "Pro 2"), and then send the "master stereo signal" which is the sum of these 4 stereo signals, to the sound technicians mixer.
Visual representation:
Pro 2 Stereo -----> Volume Pedal Stereo ----------------------------------------V
V
L------V L--------->Splitter A*--------V V
P12A Volume Pedal V V
R------^ R--------->Splitter B*----V V V
V V V
Volume Pedal Stereo -------> Passive Mixer Stereo ------> Sound Engineer
^ ^ ^
R------V R--------->Splitter B*----^ ^ ^
P12B Volume Pedal ^ ^
L------^ L--------->Splitter A*----------^ ^

Ob6 Stereo -------------------------------------------------------------------------------^
*Remember that there is only one Splitter A and one Splitter B. Splitter A sums the signal of P12A LEFT and P12B LEFT, and Splitter B sums the signal of P12A RIGHT and P12B RIGHT.
I hope this explanation makes sense.
I have some questions to this setup:
1: Will this setup create a lot of noise?
2: Are there any arguments against having a volume pedal after the main outs on the prophet 12? If yes then what are the arguments?
3: Will sending the Left output of P12A and the Left output of P12B via a splitter into the same mono input on the volume pedal be damaging to both signals? And are there other things this might cause that are relevant to consider?
4: Will having two volume pedals after each other do damage to the signal even though volume pedals are passive and dont amplify the noise floor of the signal? Are there other aspects to this that are relevant to consider?
5: Will summing all 4 synths into a passive mixer be damaging to the signal even though the mixer is passive? Are there other considerations regarding this?
6: Are there any sound quality drawbacks to summing the synths in a mixer of my own before sending it to the sound engineer? Sound quality wise, why would i want to give the sound engineer 4 stereo signals instead of just 1?
7: Would DI-boxes be important in a setup like this? If yes; how many? where would they be placed? and why?
Considerations before commenting:
-Simplifying the setup with fewer controllers because "why would you have so many controllers in the first place" is not relevant for what i want.
-I dont know so much about signals, impedance and what is important to consider when dealing with electronics, so layman explanations would help allot.
-I know that i the cable length of the chain should be as short as possible, so no need to point that out unless its relevant to something else, or if it contains more specific details like actual lengths, materials etc.
Thank you so much for reading all of this. I hope we can share ideas and figure some stuff out
