R-Mix doesn't work at all with X3E on a mono track. Very weird things start happening. The realtime graphics appear too thin (very difficult to hit target), and it ends up randomly left/right/centre. Occasionally very loud high tones come out. Turning the plugin off and on restores normality for about a second.
Shall we assume this then is a DNR situation? Just curious...
Note specifically X3E, anybody else can reproduce?
Cheers..
