6.5 Filter 6 PRESET PARAMETERS
6.5 Filter
This module is one of the main sound-shaping components of the T¨ o¨ or¨ o and is built upon
a discret analog design, the FL A847 optocoupled resonant filter. It offers a 12db/octave
low-pass with a unique sound.
To access the filter parameters, press the FILTER module button. If you
press the button more than once, the selection will cycle between filter and
shaper. The LED color indicates which module is selected:
Filter Shaper
In addition, the display will show the selected module briefly:
Filter Shaper
Make sure that the filter module is selected.
In normal mode, the Cutoff, Resonance and Env F Amount parameters can be
edited via the first, second and third encoder. To edit the Pitch Tracking, After-
touch Amount and LFO 1 Amount parameters, alternate mode has to be enabled via
the ALT button.
6.5.1 Cutoff
The cutoff frequency sets the point at which the signal is split into two bands. Frequen-
cies below that point will remain unaffected, while frequencies above will be attenuated
progressively.
6.5.2 Resonance
In a resonant filter, frequencies around the cutoff point can be emphasized. This is what
this parameter is for. The more the value is increased, the more the sound will get a nasal
character that will turn into a ringing at higher settings. When fully raised, the filter will
run into self-oscillation, producing a tone with a pitch tuned to the cutoff frequency.
6.5.3 Env F Amount
Determines how much the filter envelope (Env F) affects the cutoff frequency. Use this to
shape the harmonic content over time in order to make your sound feel more alive.
6.5.4 LFO 1 Amount
Sets the amount of LFO 1 modulation on the cutoff frequency.
