is there a way to contr several param w 1 knob?

[oilpanic]

hello.

Im looking for a way to assign several control parameters to the same one control knob or fader. Heres what id like to do:

I have my arrangement parts grouped into sub busses and usually a light compressor each on each subgroup. What I want to do is route all of the ratio values on these sub compressors to one and the same knob on a controller.

That way i could ease or tighten the compression on all subgroups simultaneously and in realtime find what feels best for the piece.

Create a new audio channel or aux and insert a compressor in the same slot as your other tracks or auxes. In the Environment, create a monitor. Cable the output of this new channel to the monitor, and drag cables from the monitor to all of the other tracks (or auxes, whatever you're using). When you adjust controls on the dummy track's compressor, the other tracks' compressors will all adjust to the same value.

 

Caveat: make sure that you don't touch any other controls on that channel, such as the volume fader or other compressor settings. Doing so will cause the other channels to adopt the same value. If you want to limit this scheme so that only compressor threshold settings make it through to the other channels, post back and I'll give you the details.

FWIW, another way to do this would be to create a fader or knob in the environment that outputted the parameter that adjusts the compressor threshold. You'd then mult that to all of the requisite channels. And for this you wouldn't need the dummy channel. You'd only need to find out what the threshold control's "fader event" specs are, and that you can easily find out by hooking up a monitor to the output of any one of those compressors and moving the threshold control.

 

To make this easy, all compressors should be in the same-numbered slot.

Sweet. This will help.

If I do the first setup I could potentially automate the paramater right?

I dont know why that would be helpul in my scenario,but I guess I could also... for instance control several es-p cutoffs with one controller using the same method.

thanks Ski!

You're totally welcome!

 

With either method you could automate the changes. But it's going to be easier to do with the first method (creating a dummy channel).

That is if your version of Logic allows it.

... also, if you are subgrouping, you will only need one instance of the plug in.

 

Let's say channels 1, 5, 17, and 26 cry out for some reverb. You can bus those channels to an aux channel with the reverb insert. You don't need to use four separate channels or four separate instances of the reverb. Just one, and it is easy to adjust this way.
