over tonal dynamics as well.

The S3000XL’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 the S3000XL, especially with certain sounds. As a result, take care to

watch levels. The distortion produced by digital circuitry is not as pleasant as that

produced by the old synths (unfortunately!!) so we can’t expect the pleasant overdriven

sound from a sampler - if you are after that sound, then sample the distortion from the

synth!

Let’s now have a look at the filter’s parameters.

The parameters across the top of the page follow the usual convention and allow you to

select the keygroup for editing, select whether you wish to edit just one keygroup or all

keygroups simultaneously and, of course, you can select another program for editing if

you wish. The other fields on this page are:

This shows the current keygroups key range.

This allows you to set the filters cutoff frequency. As you decrease this

from 99, you will remove the upper harmonics resulting in a softer tone.

This can be used to great effect on acoustic instruments (especially those

that have been looped) with velocity and envelope shaping to restore the

natural harmonic dynamics and movement to the sound. On synths, you

may sweep this with all sorts of controllers for a wide range of synth

sounds.

Here you may set the keyboard to track the filter. This is so that you can

achieve an even tone across the keyboard range. +12 is the default and

this tracks the filter octave for octave - i.e. for every shift of pitch of one

octave, there is an according shift in harmonics.

This allows you to sharpen the point at the cutoff frequency thereby

emphasising the harmonics at that point. The sound changes from a soft

‘waaa’ effect to the characteristic ‘weeow’ effect with high resonance

settings. The range is 0-15. High resonance settings can be used for

classic synth bass sounds and, simply by sampling raw synth waveforms

(i.e. without using the synths filter, etc.), these may be used as the basis

for some powerful synth sounds through these filters.
