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 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.

EDIT: tried updating to REW 5.40 Beta 76, nothing changed.

I have tried restarting Windows but nothing changed.

I had inadvertently selected the the generator option to send the signal to the timing reference output. REW's author was incredibly fast in helping me out on REW's forum.

All good.
