23.13.3 Filter/Global Tab
The Filter/Global tab contains the lter parameters for the instrument, as well as global
controls.
The Filter Section
Tension's Filter Section.
Tension's Filter section features a highly congurable multi-mode lter that sits between the
String and Body sections. In addition, the lter can be modulated by a dedicated envelope
generator and low-frequency oscillator (LFO).
The lter's chooser allows you to select the lter type. You can choose between 2nd and
4th order low-pass, band-pass, notch, high-pass and formant lters.
The resonance frequency of the lter is adjusted with the Freq slider, while the amount of
resonance is adjusted with the Res control. When a formant lter is chosen in the chooser,
the Res control cycles between vowel sounds. The Freq and Res controls can each be
modulated by LFO, envelope or note pitch via the sliders below. Note that the LFO and
Env sliders have no effect unless the Envelope and LFO subsections are enabled.
The Envelope generator is a standard ADSR (attack, decay, sustain, release). This section
can be toggled on or off via the switch next to its name.
The attack time is set with the Attack knob. This time can also be modulated by velocity via
the Vel slider below the knob. As you increase the Vel value, the attack time will become
increasingly shorter at higher velocities.
