This function can be used to modify the filter cutoff frequency of active voices during their entire life time. You need to pass the note ID of the voices you want to alter. This function will change the cutoff frequency of all active voices associated with the requested note. So if you are using a layered instrument patch, then it will change the cutoff frequency of all layers.
The cutoff frequency changes set by calling this function are always applied relatively to the cutoff frequency calculated by the synthesis model and sampler format. That means the various sources of cutoff frequency factors like Filter Envelopes, Filter LFOs and other cutoff frequency factors that may be defined by the instrument patch, are always processed and calculated for the voices first, and the final cutoff frequency applied is always a relative combination of all those factors and the one set with this function call. Or in other words: you cannot replace the cutoff frequency set by other synthesis sources with this function.
