longDescription = ''
Each section has an active/bypass switch, frequency, bandwidth and gain controls.
There is also a global bypass switch and gain control.
The 2nd order resonant filters are implemented using a Mitra-Regalia style lattice filter.
All switches and controls are internally smoothed, so they can be used 'live' whithout any clicks or zipper noises.
This should make this plugin a good candidate for use in systems that allow automation of plugin control ports, such as Ardour, or for stage use.
