The S3000XL 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.

FREQUENCY

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
