two faders controlling eachother

Hallo everyone!

Is there any way of having multiple faders controlling eachother? If I want to have one fader in a subpatcher controlling f.ex. volume in a patch, and another fader another place (for visual representation) controlling the same parameter. Then It would be nice that each faders were controlling eachother, so I won’t close the first patcher, then forgetting i have set the volume, and thereafter trying to control it somewhere else.

Don’t know why, but this works.

Jeremy, your version seems to be the “easyst” – but wouldn’t the use of “pattr” mean that what ever setting the fader is set to, when the patch is closed, is the setting it would be set to, whenever the patch is opened up again? (havn’t looked into the pattr yet… just think i have a vague idea of what it does).

You can turn that off – @autorestore 0

cheers but still just as baffled none of the faders seem to be connected to each other. is the information being sent remotely.

had a go at making it but dont recognise the two coloured boxes with the number 1 in them??????

They are the inlet and outlet objects.

You actually have done something wrong. Included you find an image of what it should look like. In the original post the value, send and receive objects are inside a patcher. Personally I don't think that this is the best way of making a stereo fader, or that the gain object is a useful object in terms of good gain control. Included an image with an expression based on a db scale, that has feel similar to the fader of a mixing desk. If you use that value to multiply two (or more) signals, one fader allows you then to control multiple levels at once.

ive got it now it works thanks so much johan. i couldnt get the second one to work though, i found a tutorial in max showing how to have a numerical decibel gauge the only problem with it was that as im using drum hit samples the sound was over before you had chance to read the level is their any way to get the highest peak level to stick in the gauge for around a second or two.
thanx lee

hi everyone.
I want to use the gain control that give the decibel reading however i really want to use the gain slider rather than the normal slider just for ascetic reasons. as the highest value of a normal slider is 127 and a gain slider is 157, is their any way i can make the highest value of a gain slider to be 127, i tried connecting an object box stating – 0.236 but obviously this just subtracted 0.236 off of the last hit value. any ideas anyone.

check out the (scale) object :) pretty easy with that one, or change the sliders max value in the sliders inspector (mark the slider, that press cmd+i)

Dec 29, 2010 at 2:32pm

hi johan thanks for the slider that works more like a mixing desk fader, but I now have max 5 and i have tried to recreate it. however i cant seem to create the expr pow. could you please post it me as a max 5 patch. thanks lee

Dec 29, 2010 at 2:40pm

No worries johan I have done it i had a typo in it. thankyou

Hi Johan.

I want to use more of these faders that communicate with each other. but want one fader to communicate with a specific fader and another to communicate with a different specific fader. how is this possible. fader A talks to fader B then fader C talks to fader D.
Thanks Lee.

Hi I found the answer to my above query. but i have noticed that this patch makes my patch work either realy slow or crash max.
Thanks Lee
