There is absolutely no way you successfully adjust two knobs at the same time on a multitouch display, let alone while doing live music. They are barely usable one by one.
There is a reason people serious about doing music keep using physical knobs to change values in their software. I’m entirely convinced the sole reason DAWs use virtual knobs despite them being such a poor UX element is because people will map them to MIDI knobs anyway and that keeps the software and physical world looking the same.
