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

[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.

@EEight Thanks, I'll give that a try.

I upgraded to Pd 0.55.2, and still get the same message. How can I find out what the problem is?

I occasionally get an "Audio I/O error" message in red on the Pd console. I'm not getting any other clues what the problem is. The patch sounds the same whether I get the message or not. What's the problem? What's the fix?

This is happening on Windows 10.

@jameslo Thanks! That works better.

There is a problem with Pure Data patch "3.8.1.1. rfft array" on this page.

When I run the patch, I get a second peak off the edge of the graph, as you can see in the attached image. I'm using Pd 0.55.0. Is this a problem with the patch or with Pure Data? What's the fix?

I have a large patch that has gotten very messy because of all the lines connecting objects. I'm considering replacing most of the lines with sends. Does send have more overhead than lines?
