cutoff / cutoff2

Sets the cutoff frequency (Hz) of the filters.

Note that while this is specified in Hertz, filter LFO depths in the SFZ 1 spec are in cents. There are two filters in series - the cutoff frequency of one is controlled by cutoff, that of the second by cutoff2.

Examples

cutoff=343
cutoff2=1200
cutoff_cc1=1200
cutoff2_chanaft=1200
cutoff2_polyaft=1200

Both filters can be used be used to have both a high-pass and a low-pass filter, like this:

cutoff=1200
resonance=6
fil2_type=hpf_2p
cutoff2=250
resonance2=3

Practical Considerations

Setting cutoff to 0 behaves differently in diffrent players.

ARIA/sforzando : filter disabled, oncc disabled rgc sfz : filter off, oncc working Dimension Pro and Rapture : lowest cutoff value, oncc working sfizz : no sound BassMidi : filter off, no oncc support yet
