1075 equalizer.  Each section has an active/bypass switch, frequency, bandwidth and
1076 gain controls.  There is also a global bypass switch and gain control.
1077
1078 The 2nd order resonant filters are implemented using a Mitra-Regalia style
1079 lattice filter, which is stable even while parameters are being changed.
1080
1081 All switches and controls are internally smoothed, so they can be used @code{live}
1082 without any clicks or zipper noises.  This makes this plugin suitable for use
1083 in systems that allow automation of plugin control ports, such as Ardour, or
1084 for stage use.")
