Filters

BLUE offers two HQ analogue modelled filters for subtractive alteration of the sound. Cross-fusion synthesis also allows you to use these filters in FM type sounds offering you new directions and possibilities. These filters have the most important modulation parameters pre-defined, such as Envelope, Velocity and Modulation Wheel. This makes sound editing easier and faster.

In the following we will describe the controls for Filter A and Filter B. Controls are for both filters the same.

Parallel / Serial

In parallel mode Filter A & B are both running separately, in serial mode the output of Filter A is then passed into Filter B.

Type

Type of filter available, these are

  • 6dB Low / High pass filters
  • 12dB Low / High / Bandpass and Notch filters
  • 24dB Low / High / Bandpass and Notch filters
  • Ring modulator
  • Comb Filter
  • Vox formant filter

Destination

Controls where the filter output goes to next, these are

DryBypasses the effects
FX AGoes to FX A
FX BGoes to FX B
FX A+BGoes to FX A and FX B

Note: in case you route the filter to Dry and do not hear any sound, make sure that the dry volume in the GLOBAL screen is not set to off

Frequency

Cutoff frequency of the filter.

Q

Resonance of the filter. Sounds at the filter cutoff frequency is emphasised by the resonance. For the 6dB filters types it has no effect, for the Ring filter it controls the amount of ring modulation, for the Comb Filter it controls the amount of feedback and for the Vox filter the bandwidth of the formant filters.

Distortion

Controls the pre-filtering saturation distortion. For the Vox filter this controls the vowel of the filter.

Envelope to Filter

Controls how much the filter envelope alters the filter frequency. For positive values the filter frequency goes up when the envelope increases and for negative values the filter frequency goes down when the envelope increases.

Velocity to Filter

Controls how much the filter frequency changes with the velocity of the note. At positive values lower velocities give lower filter frequencies and for negative values lower velocities give higher filter frequencies.

Keytracking

Controls how much the filter frequency changes with the key pressed. For positive values, higher notes have higher filter frequencies than lower notes. For negative values lower notes have higher filter frequencies than lower notes.

ModWhl to Filter

Controls how much the modulation wheel controls the filter frequency. For positive values, higher modulation settings cause higher filter frequencies, for negative values higher modulation settings cause low filter frequencies.

Filter Volume

Output volume of the filter.

Filter Pan

Pan position of the filter.

Tip: you can set a filter to Bypass and use the panning to pan different the output of the oscillators without filtering them, or you can use it for panning modulation effects
