REW Beta Release All of a sudden REW generator always outputs L channel with other channels

[gorman]

I am completely clueless as to what might have happened.

I am using REW 5.40 Beta 21. I tried updating to REW 5.40 Beta 76, nothing changed.

I was conducting a series of measurements, first with tripod and then with MMM method.
I took a whole set of L-C-R-SL-SR in six different positions. Levels were fine. Microphone tripod mounted.

Then I switched to MMM method and I wanted to compare two different Dirac target curves I am using.

First curve measured, took 4 measurements per L and R channel. Levels were fine.

Then I switched to the second curve. Took another 4 measurements per L and R channel. R channel was about 5-6db louder. At first I thought I had mistakenly raised the AVR volume but no, it was the same.

After a minute or so of fiddling I noticed that, basically, whatever channel I select in REW Generator, L channel keeps on reproducing sound. So when I selected R channel in the generator I was getting L+R. If I select C I get L+C, and so on and so forth for the two remaining side channels.
I had not touched REW configuration in any way.

Tested with other ways of generating "per channel" sound (including an old 5.20.14 REW installation) and the problem happens only with REW.

I have tried restarting Windows but nothing changed.

Have you selected the generator option to send the signal to the timing reference output? Bottom of the generator window.

That was it! In my defense, at 300% zoom level (what Windows suggest for my 77" screen), that last line of options is only partially visible. I surely have clicked on it by mistake, while hovering around the area with the mouse and then did not see it once I started checking what might have gone wrong.

This is how I see it (now I am curious about the "Invert second output" option, which I had never noticed either).

I use an RTX 4070 GPU if the video driver is of interest. Willing to provide any info you might need to "fix" this visualization error.

Also, I take the chance to first of all thank you for the awesome program. Considering the incredibly fast reply from you I'll proceed with a donation later tonight, something I have postponed for far too long.
THANK YOU!

Use a lower scale factor.
