After update to 4.8.1 and, after, to 4.8.7 slider of main output, which at top of the window doesn't control volume at all. System win10, problem not depends on audio device and drivers. Some time I didn't remove 4.7.8 because it worked fully properly, but now I, supposing that presense of older version is reason of problem, uninstall 4.7.8 and really regret on it. I purchased this soft 5 years ago, being found it was really woth of it. Support doesn't pespond. I see, I'm not only one with this trouble: https://tonelib.net/forums/threads/global-volume-does-not-work-anymore.17942/ https://tonelib.net/forums/threads/...o-the-input-slider-on-left-of-fx-chain.14934/ Seems to be product really goes bad.
