 -- Filters (x = oscillator) -- Filters (x = oscillator)
 +-- There are two different filters in VividShaper. One that you apply on the actual waveform and
 +-- one that you apply as an insert after the output of the oscillator. Both are biquad filters.
 +-- Common for both filters is that you need to create a filter array containing the biquad values.
 +-- You don't need to set the values yourself. Instead, this array is created using three different
 +-- functions, depending on what kind of filter you want. The notein argument is optional from v2.0,
 +-- but can be used to let the cutoff frequency follow the note.
