RE: you CAN'T separately process the left and right channels

That's my point. You could before 2012. And you're supposed to be able to now.

To edit one of the two stereo tracks . . .

Dbl click on an audio track. Or click on the audio editor window icon.
The audio window pops up. It has two "tracks". Left (on top) and right (on the bottom).

There's a track select field/drop down. Open it. There you select . . .

Left track only, right track only, or both tracks.

This selection determins whether you edit one, or both tracks.

Select LEFT track only.

Now you're supposed to be able to edit just the left audio track.

So you can tweak it, delete parts of it. EQ or change volume. Etc. Without
changing the other track.

Let's say you want to delete the left track so there's no audio data in the track.
(Why? you ask! For one thing, your .seq file will be a LOT smaller if you clean out what
you don't need. Many of my .seq files are between 350G and 900G. It alsao improves the sound of
your backing track if you remove all that unused data.

BTW: I also delete any audio where nothing is recorded. Like if you have one track with a drum fill.
And that fill is used just once, or a few times. And the rest of the track is just "empty". It might
be empty. But that doesn't mean it's clean. I delete all the audio in between those fills.
Or if one track is a guitar solo. And there's nothing before the solo or after it but dead space.
I delete all of that, too.

So, in the drop down, you select "Left only". Then you hit the "select whole track" button. Now the entire left (and only left) track is highlighted. Now either hit "delete" on your keyboard, or hit the "cut" icon. BAM! Both tracks are gone!

I've been doing this for years. Never had an issue until 2012 came out. And Tech support (who first told me I was doing something wrong!) tried it while I was on the phone.

I got a long . . . "Hmmmmmmmmmm. I'll have to report this. It's a glitch!"
