I encountered a timefactor reverse delay bug way back in old releases, found a way to work around it, and forgot about it. Yesterday I decided to test to see if the bug was still there. It seems to be. Or maybe I am doing something that is aggravating it.
I set up a reverse delay patch, set mix to vary 12% to 100% with CC, one voice only, feedback 0, xnob set to about 5 msec. When I store the patch, load a new unrelated patch, then come back to this patch, the wet effect volume is down about 75%. If I adjust the mix level, it does nothing to bring it back up, even at 100%. But if i tweek the xnob it comes right back. It's as if the wet signal has gone through a master fader set on 25% no matter how much I mix in. The mix still works proportionally, in that it now fades from a very weak 12% to a very weak 100%, dropping out the dry accordingly.
My workaround was that I had my CC pedal set to control xnob from about 3 to 7. Touching that pedal brings it back. It still works. Since I also have my mix tied to the CC pedal all the time for setting levels and I use it constantly, this hasn't been an issue. Just more curious about what it is.
