Defines a bank of bandpass filters in parallel whose outputs can be scaled using a function table. Kind of like resony, but with scaling.
Storing the scaling values in a function table allows you to do some pretty cool things without writing a lot of code. You can have several different 'eq' settings in different function tables and ftmorf through them with an lfo or step sequencer. You can put values into the ftable using pvsftw and do some nice cross-synthesis. then you can modulate klow/khigh (the lowest and highest cf's) and/or kres, and seriously distort the original fsig; etc.
