THE FILTERS
The next group of pages deals with the S2000’s filters. The S2000 is equipped with
12dB/octave lowpass resonant filters as found on many analogue synthesisers. As well as
using them for the tonal modification of acoustic samples, they also allow you to totally
transform a sound.
‘Lowpass’ means that the filter will allow low frequencies to pass through unaffected whilst high
frequencies are removed.

As the cutoff frequency is moved downwards, so high frequencies are gradually removed.

This is very convenient when dealing with samples of acoustic instruments because as notes
die away, they tend to lose their higher frequency content first. By applying an envelope
generator to the filter’s cutoff frequency, we can emulate that on the sampler. Another
property of sound is that when it is played loud (ff) it is generally brighter than when it is played
softly (pp). Using the filter and applying velocity (or controlling the output of the filter’s
envelope generator using velocity) we have control over tonal dynamics as well.
The S2000’s filters are equipped with resonance. This allows you to selectively boost the area
around the cutoff frequency thereby boosting certain harmonics.

Although it has some uses when trying to accurately reproduce some acoustic samples, its use
is more suited to synthesiser effects. You will note, however, that when resonance is used,
because of the gain increase that takes place, it can be easy to overload the output stages of
