Does it matter if I plug a 0-5V CV input into it? Will the device accept the input and split it all the same, without the need for any design changes? Or will it need to be designed differently to cater for both CV + EXP on the input.

"The (our) stereo mod converts four GCX loops to stereo/TRS.
And, the loop returns are ground (sleeve) lifted.
So, it's unlikely it will work as you desire (if at all)... but, you could try it."
So I'm guessing it won't work?
mysteryroach wrote:Even more questions sorry:
I have 2 pedals that operate on EXP and also 0-10 CV (One with separate jacks for CV and expression that you can operate with 2 separate controllers, the effect of which is summed - and one with a single plug that can handle both). I plan to use these both in the 3-way splitter section of my custom Copilot Broadband (the CV->EXP converter). Leaving 1 slot open that can only be filled by a 10V pedal (if there's voltage bleed). Could I fill that with a pedal that doesn't take expression, but does take 0-10V CV? Will the reference voltage from the other pedals bleed into the splitter and then into the non-exp pedal, operating on it as if a control voltage would? That could be a way to turn lemons into lemonade.

The RETURN path for your CV will then be faced with the task of scaling a 0-10 volt feed to whatever voltages are acceptable at the pedal

I kinda glossed over this. Does this mean I need to scale the higher voltages down to a lower voltage (i.e. acceptable by the other pedals) on its return path to the splitter? So instead of, for example, having mainly 5V outputs and a couple of 3.3V that need circuit protectors - I would have mainly 5V and a couple of 10V with circuit protectors. Or am I just getting confused now?
Could I do both? Scale the return path down at 2 of the 10V outputs to 5V. Scale the incoming 5V path down to 3.3 at the 3.3V outputs. Or does it not work that way.

Say I have 8 5V pedals, 2 10V pedals, and 2 3.3V pedals. I would only need circuit protection on the 4 non-5V outputs?
I wouldn't need it on 10 outputs? (e.g. the non-3.3V ones if you're scaling down, the non-10V ones if you're scaling up)

there are various options for your situation, since you want to have multiple inputs that you want to route an specific out and use a footswitch, get some multiplexers ic and have a predetermined idea if you have 8 inputs and have 8 outs you can route it, and it will solve your problem, for more efficient (timely and cost), all the inputs should be converted to cv internally and it will be easier (less parts and design) and feed them to the broadband (so you will have 6 outputs of your 8 devices, and can solve the ones that needs exp, 9v, 3.3v) and the others (ideally the ones that receive 0-5v) will be controlled for from the 8in/8outs device.
the only drawback is that you will have to scroll from each pseudo preset (if input a is a sequencer, and you want to go to envelope, but envelope is input f, the. you will have to go from a to f clicking the footzwitch). is an example because you could configure how they will be routed but once is routed, it will stay that way. but i dont think in mid song you will use (while playing) different inputs with the same out (like 4 bars of the solo has a sequencer of the cutoff in a filter then 2 bars into a lfo next 2 bars envelope last 8 bars noise source)
