[rev3~] has two audio inputs. It it true stereo? The help file doesn't say. It just shows just a single audio source that is routed directly into one input and inverted into the other, but doesn't explain why it does that.

Also, [rev3~] has 4 outputs. What are the functions of the third and fourth outlets? The help file doesn't explain it.

@jamcultur Yes, the 2 audio inputs are left and right.
[pd reference] at the top right of the help file gives a bit more info.
But [rev3~] is not an object.
It is an abstraction, so you can open it and see exactly how it works.
There is also a little more information inside the abstraction.

@whale-av Thanks! What is the purpose of the third and fourth outlets? How should I used them when generating stereo output?

@jamcultur Hard to tell exactly without listening, but the delays are a little longer for 3 and 4, so should create a wider (more spacious) image...... "spread" in hardware reverberators.

@jamcultur it’s just 4 outputs of audio, as in a quadraphonic setup. You can use just one, two, three (why not?) and whole four of them. If you only have 2 outputs, just use 2 of them or even combine them if you will
