The EXS24 mkII filter can operate in several modes, allowing specific frequency bands to be filtered (cut away) or emphasized.
Most filters do not completely suppress the portion of the signal that falls outside the frequency range defined by the Cutoff parameter. The slope, or curve, chosen for the lowpass filter expresses the amount of rejection below the cutoff frequency in decibels per octave. The steeper the slope, the more severe the effect on signal levels below the cutoff frequency.
Click one of the following buttons:
HP (highpass): Allow frequencies above the cutoff frequency to pass.
The slope of the highpass filter is fixed at 12 dB/octave in HP mode.
LP (lowpass): Allows frequencies that fall below the cutoff frequency to pass. Click any of the four filter buttons to engage the lowpass filter and to select a filter slope.
24 dB (4 pole): Use this setting for drastic effects, such as cutting off all but a few notes.
18 dB (3 pole)
12 dB (2 pole)
6 dB (1 pole): Use this setting for creating a slightly warmer sound without drastic filter effects—to smooth overly bright samples, for example.
BP (bandpass): Allow a frequency band directly surrounding the cutoff frequency to pass. All other frequencies are cut.
The Resonance parameter controls the width of the frequency band. The bandpass filter is a two-pole filter with a slope of 6 dB/octave on each side of the center frequency of the band.
