autopilot wrote:the broadband outs are independent so there wont be any bleed from one output to another (you can ran one out going into a 9v cv device, another out to a 5v cv device and the other out to a 3.3cv device), even when they all share the same source (to sync).
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)
So, convert all TRS inputs to 0-5V CV (if not already cv) and then make it just be a TS splitter? May as well, as it'll be cheaper. I could make it even just have TS inputs and only accept CV (my reflex does CV). But I may as well allow a EXP-in - for versitility.
What I'll do - is have the switching unit run only my 5vs. And run everything else off the Broadband as a universal conversion unit or sorts. Like you're also suggesting I think.
If I really want to any of my 3.3's off the switcher (in case the Broadband gets full) I can maybe get one of those cables Disaster Area are making (converts 5V->3.3V). If I need to run shit off it in the future, just put the conversion in the cable. Although I'm not sure if you can make a similar cable that will amplify the voltage up to 10V. I assume something like that would need to be powered? (whereas a reduction in voltage is just a resister) It would be nice to know what I would need to do in the future to support >5V CV-only devices - with full voltage range. It's not something I'll solve today (i.e. in the switcher) - but it'll be nice to know what would be involved.
Anyway, when you say "input f" - having
that many inputs (6) was an extreme luxury even in the first post, that I had since rolled back. However, your idea of a footswitch never even crossed by mind. I had wondered if it was possible to input the expression units through the GCX to do the switching. But I can input into the patch-bay instead (being that it may not work through the GCX), and use the GCX as a footswitch, then I can have midi control.
I could either just cycle between 2 inputs. Or have 4 inputs, and 2 4-way rotary switches (to determine what inputs get cycled between using the footswitch). Or on/off switches for each input, selecting which inputs are cycled between - i.e. pressing the footswitch goes to the next input that's on (I assume that may be a little more complicated though?) - maybe have a reverse switch too.
Could I have multiple midi operated footswitches to expand the number of inputs I can cycle between? E.g. if I had 2 footswitches, could it be configured to choose input 1 when footswitch 1 is pressed, input 2 when footswitch 2 is pressed, and input 3 when both are pressed at the same time? Tbh, this sounds like a significant step up in complication though.
In this case I wouldn't have a (regular) switch for each output (i.e. the inputs at the splitter will all receive the same CV). While it would be nice to include a per-outlet switch, I'm unlikely to bother including it i.e. the footswitch decides whether [in1-or-in2] OR [in3-or-in4] is selected. However, it's not exactly necessary. It's a pretty staggering amount of control as is, so I think i'll keep it simple:
2x EXP/CV-in
8xCV-out
5V in/out. (so only use 5V input/output devices unless additional conversion steps are added - e.g. cable or broadband)
EXP->CV conversion at the input
Inputs switched BEFORE the splitter
Footswitch control over switch
GCX/GCP interfaces with footswitch for midi control
