Default Edit left and right of a track separately

I would like to know how I can edit the two sides of a stereo track, left and right, separately.

Two scenarios interest me the most:

1. Take a guitar stereo bus and eq left and right differently to widen the sound (in detail: Choose some small frequency bands and make opposite cuts and boosts on both sides).

2. Take a guitar stereo bus and add reverb to the opposite side (in detail: take the left/right signal of the stereo bus, send it to another track, add reverb to that track, make it 100% wet and pan it to the opposite side, that is, the reverb of the left channel will be on the right side and vice versa)

>> What is the easiest way to achieve that?

When I search, I typically always end up with descriptions about how to split a stereo track in two mono tracks. What I was really hoping to find, is a solution that allows me to "virtually" do that, something like those Reaper plugins (can't remember the name) that allows to split signals in different frequency bands.

My prefered solution would be some Reaper internal plugin.
If there is none…
...what about external stereo eqs?
…or could I try to misuse the EQ section of Torpedo wall of sound?
…or did I simply search the wrong way because I don't know the right keyword to search for?

You can use the pin connectors in your track to route to different fx.
For example, if you use two instances of ReaEQ on your stereo gtr track - uncheck the ins and outs from channel 1 in one and channel 2 on the other, thus giving you two mono EQs, one on each side of the stereo file

and for the reverb thing, you can set up two sends, both with a mono source - one from channel 1 and one from channel 2 - then you can route them through a reverb and send them wherever you want

1. Pin connectors as mentioned

2. Can also be done with pin connectors (invert input OR output) or by setting the Reverb track's Width control to -100%. Even in default Pan Mode, the Width control is available in the track's I/O window.

Outside of the suggestions already offered, some EQs allow editing per side.

Download this FX chain and follow the instructions in the thread, it will work fine with most stereo reverbs. AKA the reverb output is always a mirror image of the stereo placement of the instrument so if the guitar is hard right, reverb is hard left - if the guitar is at 2 o'clock, the verb will be at 10 o'clock and so on - but since it uses 4 channels, a single chain can handle standard reverb duties and mirror imaged at the same time based on which channels you send to the reverb 1/2, 3/4 or both. You'll want to replace the reverb with your choice and reassign the pins as they are in the one that is there already.

Thanks to all of you.
I have been playing around with your information and that of chapter 17 of the user guide.

Pin connectors are somewhat new to me, so still a bit confused.
This is what I did, is this correct?

* go to fx bin of stereo bus
* load eq 1
* go to "2 in 2 out" menu
* set "Track Channel 1 -> CST in 1"
* set "VST Out 1 -> Track Channel 1"

so that it looks like this:

|x|-|_____|x|-|
|-|-|_____|-|-|


* load eq 2
* go to "2 in 2 out" menu
* set "Track Channel 2 -> CST in 2"
* set "VST Out 2 -> Track Channel 2"

so that it looks like this:

|-|-|_____|-|-|
|-|x|_____|-|x|



More questions:

1. Can I leave "Track channels: 2" on the stereo bus untouched?
Or do I have to change to "Track channels: 4"?

2. If I change to another preset in a plugin, it seems that the "2 in 2 out" menu always goes back to its standard setting?

|x|-|_____|x|-|
|-|x|_____|-|x|

Can I prevent this?

Do not bus before processing
or use eg. LR eq

Sorry, I just don't understand that sentence.
What exactly are you referring to?
Is that the solution to a problem or a different approach?

Now you have **two** FX chains ready to go. The one I posted for you above for a mirror-imaged reverb and now below which is the Stereo EQ:

EQ:

StereoEQ.RfxChain

Reverb:

https://forum.cockos.com/showpost.ph...1&postcount=57

All you have to do now is download and use them by placing them in Reapers FXChains folder.

The pin connector settings are stored as part of the preset. You could go through and save an L and R version of the stereo presets that you use often, or save FX chains with both already set up that way.

Sorry, I just don't get the wording.
It seems that the pin connector is the key and I just need to understand how to put "pins" there.

I made two screenshot, the two settings for the left (screenshot.28.png) and right EQ (screenshot.30.png).
Is this correct?

This would have been my next point anyways.

Here is what happened:

I downloaded your files and tried to set them up:
* Go to FX bin
* Open FX > Add FX chain

As regards "StereoEQ.RfxChain" I get the result from the attached screenshot, that is, the pin connector settings is in the standard form (just the same as if I load the plugin and don't change anything).

That confused me.
I was expecting it to be different.
And seeing what it looks like exactly being my key to understand the whole thing.
I also watched the video for the other FX chain but couldn't transfair the description from there to how to approach this one.

So again,
* did I miss something else?
* did you leave something out that you think is clear anyways?


---------------------

PS: As regards the other FX track "LCR Reverb.RfxChain" it says:
"The following effect is not available: IX/Switcher"

I tried to find out if I have to download it somewhere or if it just bears a different name in my installation but did get further so far.

Here's the one for ReaEQ, I'll post the one for reverb in a bit.

I had a look at the second fx chain just to see if I got along.
Unfortunately, I get stuck with the third step, the 8-channel-input-switcher.

I have that plugin, but mine looks a little different and the pin connector settings are quite different and have different names (see screenshot).

But that is just some quick feedback so you know how it is going.
I will jump to the eq chain and see how that goes.

Though you can probably make it work with the one you chose the there are two...

8 Channel input switcher

8-Channel input switcher

I'm using the first one, the one without the hypen (-).

I also just noticed one of those JS switchers isn't in my portable install so I don't know why it is now missing in later installs, if you don't have it, let me know I will send.

For no 2. "reverb on opposite sides" I made it like this, now:

* go to stereo bus
* set "Track channels" to 4
* add "ReaVerbate" to plugin bin
* set "2 in 2 out" to

1 => |x|-|.....|-|-| => 1
2 => |-|x|.....|-|-| => 2
3 => |-|-|.....|-|x| => 3
4 => |-|-|.....|x|-| => 4

* add "JS: 8x Stereo to 1x Stereo Mixer" to plugin bin
* turn everything to minimum level except for "Level 1+2" and Level 3+4"

Seems to work ;-)
