Space Designer lter
Space Designer lter parameters
Space Designer’s lter provides control over the timbre of the reverb.
You can select from several lter types and also have envelope control over the lter cuto,
which is independent of the volume envelope. Changes to lter settings result in a recalculation
of the impulse response rather than a straight change to the sound as it plays through
the reverb.
The main lter parameters are located in the lower-left corner of the interface.
Main lter parameters
•
Filter On button: Click to switch the lter section on or o.
•
Filter mode knob: Rotate to set the lter mode.
•
6 dB (LP): Bright, general-purpose lowpass lter mode that retains the top end of most
material while still providing some ltering.
•
12 dB (LP): Warm, lowpass lter mode without drastic lter eects that smooths out
bright reverbs.
•
BP: 6 dB per octave bandpass design that reduces the low and high ends of the signal,
leaving the frequencies around the cuto frequency intact.
•
HP: 12 dB per octave/two-pole highpass design that reduces the level of frequencies that fall
below the cuto frequency.
•
Reso(nance) knob: Rotate to emphasize frequencies above, around, or below the cuto
frequency. The impact of the resonance knob on the sound is highly dependent on the chosen
lter mode, with steeper lter modes resulting in more pronounced tonal changes.
