Sweeping the bandwidth is a little like sweeping the resonance, but
different. With a narrow bandwidth, the peak remains at unity instead of
being amplified as with most filters. The effect is not as pronounced as
high resonance. You can also make the bandwidth much wider than a normal
bandpass filter, so you get effects ranging from lowpass and/or highpass to
bandpass all in one filter. Maybe we should consider it the first morphing
filter? If you move the bandwidth and frequency cutoff at the same time it
can definitely sound like all three.
