The filter parameters are fully interpolated, so you can modify them without causing any glitches in the audio being processed. In addition, the SVF Control provides a Glide control parameter that allows you to control the interpolation rate. This allows you to configure the filter so that it reacts instantly to parameter changes, or has a slower gliding behavior.
The F parameter allows you to set the center/cutoff frequency of the various filters. The Q parameter allows you to control the resonance at the cutoff frequency. Larger Q's will increase the peaking at the cutoff frequency.
