This is an interesting suggestion. At the moment, using knobs to transmit MIDI CC will also change the internal parameters. If enough people ask for a mode where the knobs ONLY transmit MIDI CC, perhaps it will get worked into a new release.
At the moment there don't seem to be many people using the knobs as MIDI controllers, but maybe it will catch on once people realize how useful it is.
A workaround for now might be to turn Catchup ON. At lease then the internal parameters won't change until you move the knob to the saved value.
