I submitted feedback via Reference software, but figured I post the question here to see if anyone else has the same problem. I tried searching for this problem but I couldn't find an answer.
Configuration: Windows 7, Reaper 6.02, 64-bit VST 4.4.2 Build 85.
Different corrections are supposed to be applied to the left and right speaker channels (per the visual of the loaded profile), but the same correction seems to be applied to both left and right channel outputs of the VST.
To verify the problem, I feed a mono signal into the VST (or hit the mono button in VST) and disable Listening Spot Correction, then sum the left channel VST output with an inverted right channel output and it nulls completely (-inf). If I then enable Listening Spot Correction in the VST (changes the level of a channel by a few tenths of a dB), then I no longer get a complete null (i.e., the left and right channel outputs of the VST are no longer identical, and this is verified by the result).
I get the same null test result when loading several different profiles. Looking at a spectrum analyzer of the left and right channel VST outputs (when the VST is fed with a noise generator), it appears the correction for the left channel is being applied correctly to the left channel output of the VST but the left channel correction is also being applied incorrectly to the right channel output of the VST.
How can I get the left and right output channels of the VST to have the correct channel-specific corrections applied? Thank you for your help!
