control groups of faders

I would like to be able to take control of a group of faders with a single fader but keep all the values of the faders in the group relative. For example, one fader would be at -6, one fader at +2, one fader at -12 etc, then when I altered the value with the group control fader, all the other faders would increase and decrease relative to their current values. All the faders would have an overall range of -80 to +12, though they may have to be set to significantly larger range than the group fader to prevent "bottoming out" at maximum range and picking up the wrong values when the group fader is adjusted in the other direction.
(edit: nope, I don't think that setting larger ranges will work. I need another way to pick up the correct values when the group fader has made a sub fader reach maximum or minimum values)

Also as a bonus, I would like to be able to engage a switch for each fader that would assign or unassign the fader to the group, which I think should be as simple as placing a switch and a pass event flow module before the sub fader.

Any brilliant minds want to have a go at this one?

this?

here there is the botoming on reaching limit, but if you put higher range, then folow with a second fader of -80...12 should keep "true" relative.

So easy...!
Bottoming out is still a problem and it doesn't really work for me to increase the range of the faders...
I would be ok with a hard limit where if any fader reaches -80 or +12 then all the faders will go no further as a group.
Trouble is is that if I try something like a stop event flow from the master fader when a fader reaches + 12, then the master fader becomes locked permanantly unless I move the single +12 fader.
Now that I know the Delta module, I'm sure that I can (hopefully) figure something out....

I would definately appreciate a good write up on all of the Usine math modules! So many of them, I have no clue how to use!
Or maybe I should have paid more attention in school...?

thanks 23FX !
this one will be added to the compilation utils 2

just a quick thought on bottoming - would using arrays, and specifically the roll array help here?

i should have paid more attention too.
I remember I was questiong about concrete future application...
since i got usine I ve had a "direct in your face" example

personnally I tried all of them feeding with a fader and checking the console to see results, helped a lot.

im also interested in this "relative" master fader, will try to find solution for botoming as well when free time,
totally overbusy for now

, let us know if you find something.

It's true we should write a litlle example application on each math module, could be clear for those like us who forgot hehe
will try to take notes on when im using this, or this..

at clearscreen: interesting idea.

note sure ive undestood what you're after but like this you can make each fader stop being of the group when reaching limit,the master keeping on controlling the other?

btwn im sure there is a better solution via keeping true relative, will investigate too.

By hard limit I meant more that if any fader in the group were to reach -80 or +12 then the faders in the group would all stop responding to the master fader untill the master fader direction was reversed.
For example, if there were three faders in the group, one set at -12, one at 0 and one at +6 then the maximum amount the group fader could increase would be another +6 which would ensure all faders stayed relative, and the original mix ratios unaltered.

I think when using this for gain adjustments, a hard limit would be fine as there should really never be any need to increase or decrease the group gain more than a few db, and usually this would be a few db's less as gain reduction on groups of tracks is usually what is necessary when a bunch of tracks are mixed together and the summed output ends up too hot.
I hope this makes sense?
