Applying Effects to Groups of Channels

There are two ways: one is with a property of the effect, the other one is with the channel selection when applying the effect.

1. In the effect editor change the Grouping to 2, or
2. When calling the effect use paratheses: (1+3) (2+4) Effect 1 Enter

Some notes:

• You only need one of the two methods.
• Grouping two means "every other channel", i.e. the 1st, 3rd, 5th, ... channel of the selection doing the same thing.
• Method 1 is faster when calling the effect because you don't have to worry about defining the grouping in the command line, but it's less flexible
• Parentheses define subgroups. Each subgroup is treated as one object by the effect (and other syntax as well).
• Parentheses are written with [Shift] & [/]
• Offset can help write a channel selection with (), but only if there is a matching ruleset in Offset.

Does that help?

That is awesome information, thank you!  I could not find anything about either of those definitions in the documentation of forums.

I did not understand how modifying the grouping number broke up the selected channels.  The "every-other" makes sense, but would not often work in a real life scenario, just in my over simplified example.

The sub-grouping via parenthesis is exactly what I need. Obviously not intuitive given the special character.  I don't suppose the same can be done using Groups? Like,  Group 1 + Group 2 Effect 1?

Groups are "only" pointing to a channel selection.

So all the above rules apply as well.
Try it out and come back if you have more questions. 

There is a third option I think, to select the channels.

Using your example, Assign channels 1 & 3 into Group 1 (or whatever group number you choose), and 2 & 4 into Group 2 (or again whatever Group number you prefer).  Set your effect to a Grouping of 2.  Then call the effect: "Group 1 + Group 2 Effect 1 Enter".  I'm not at a board right now bit I'm pretty sure this works.

No, this wouldn't have the expected result, the console would just string together the two selections. What would work however is (Group 1)(Group 2) Effect 1 Enter
