I had this idea for parallel path on/off and dry/wet access to the screen rotaries.
For example most of the compressor emulations have at least 2 rotaties free. It would be great to be able to set the dry/wet signal with two hands in stead of having to use the touch and turn.
It would also be way faster to do it without having to volume changes in a live show, which you don’t want. I don’t really see any downsides to this idea.
