Yep, if you want two separate fx, but you can combine two inputs to mono on one Thru track, so only one needed
Cue is one method to get the audio out the OT, Thru machine is one method to bring the audio back, along with Direct monitoring of the inputs A>D
Thru is the only way you can take one of the four inputs and pan it centre
If you forgo a Thru track in favour of Direct, it will appear at the Left or right depending on the return jacks you fed it to … .you could use a small mixer prior to the return and thus do away with need for Thru track, but keep in mind a Thru also allows you to apply specific fx[quote=“Finiiiie, post:4, topic:36948”]
And if I set a thru machine the way you describe, how do I apply the audio from it to individual tracks?

I don’t follow, but a Thru will serve up a stereo Track using whichever source arrangement you chose
