• Lin button: The decay curve of the volume envelope is shaped by a linear algorithm,
and results in a less natural-sounding reverb tail.
• End Level field: Set the end volume level. It is expressed as a percentage of the overall
volume envelope.
• If set to 0%, you can fade out the reverb tail.
• If set to 100%, you can’t fade out the tail, and the reverb stops abruptly if the end
point falls within the tail. If the end time falls outside the reverb tail, End Level has
no effect.
Logic Pro Space Designer filter and filter envelope
The filter provides control over the timbre of the reverb.
You can choose from several filter types and also have envelope control over filter cutoff.
Changes to filter settings result in a recalculation of the impulse response rather than a
direct change to the sound as it plays through Space Designer.
The main filter parameters are shown at the right side of the parameter bar when the filter
envelope is selected in the main display.
Click the Filter Env On/Off button to enable the filter envelope and the filter itself. You can
use the envelope to control the filter cutoff frequency over time. You can adjust all filter
envelope parameters, either numerically in the parameter bar or graphically in the main
display using the techniques discussed in
Edit Space Designer envelopes in Logic Pro.
Main filter parameters
• Filter mode pop-up menu: Set the filter mode.
• 6 dB (LP): Bright, general-purpose lowpass filter mode that retains the top end of
most material while still providing some filtering.
• 12 dB (LP): Warm, lowpass filter mode without drastic filter effects that is useful for
smoothing bright reverbs.
• BP: 6 dB per octave bandpass design that reduces the low and high ends of the
signal, leaving the frequencies around the cutoff frequency intact.
• HP: 12 dB per octave/two-pole highpass design that reduces the level of frequencies
that fall below the cutoff frequency.
• Reso field: Emphasize frequencies above, around, or below the cutoff frequency. The
impact of the resonance value on the sound is highly dependent on the chosen filter
mode, with steeper filter slopes resulting in more pronounced tonal changes.
