Okay, if I assign quick controls in Studio / Studio Setup / Remote Devices, it does not work at all. By even stating in a “legacy information” that the feature will be discontinued, I would have thought that means it is still working currently. After having assigned the QC in Mapping Assistant, the controllers were assigned. However, trying to control Bypass in Dual Filter Plugin results in it is not doing it most of the times, but randomly it does (always turning controller to 0% or 100%). What the heck is going on here? I have been using Cubase since 25 years. What have you done?
What devices(s)?
Are your QC in absolute or relative mode?
