Maybe the K3 software should adjust its DSP bandwidth so that you get a
smooth variation of the cascaded bandwidth as you turn the knob. When the
narrower filter engages, widen the DSP a bit. There's no way to make it
perfect, but it has to be better than having the user fudge the filter
bandwidths.
