Quick Sampler Filter parameters
On/Off button: Turn the filter on or off.
Type pop-up menu: Choose a filter characteristic. Each option provides a different
tonal color and response to Cutoff, Drive, and Res control values. See Logic Pro Quick
Sampler filter types.
Cutoff knob and field: Set the cutoff frequency for the filter. Higher frequencies are
attenuated, and lower frequencies are allowed to pass in a lowpass (LP) filter. The
reverse is true in a highpass (HP) filter. In bandpass (BP) mode, cutoff determines the
center frequency of the band that is allowed to pass. Band Reject (BR) works the same
way, but the center frequency is not allowed to pass.
Reso knob and field: Boost or cut signals in the frequency band that surrounds the
cutoff frequency.
Drive knob and field: Overdrive the filter. This can lead to intense distortions, depending
on filter type.
Env Depth knob and field: Set the amount of filter envelope modulation.
Keyscale knob and field: Set the filter cutoff frequency intensity by keyboard position.
Set to zero to filter all notes equally. Set to 100% to open the filter for higher played
notes.
Envelope display: Drag points or lines in the display to adjust envelope parameter
values. Alternatively, drag vertically, or double-click on envelope parameter fields to
type in values.
Envelope Type pop-up menu: Choose the envelope type. This alters the number and
appearance of envelope parameter fields and the graphical envelope display.
Attack handle and field: Drag horizontally to set the time it takes for the envelope to
reach the initial level. Drag the field vertically.
Hold handle and field: Drag horizontally to set the time the full level is held, following
the attack phase, before the decay phase begins. Drag the field vertically.
Decay handle and field: Drag horizontally to set the time it takes for the envelope to
fall to the sustain level, following the hold phase or the initial attack time. Drag the
field vertically.
Sustain handle and field: Drag vertically to set the sustain level, which is held until
you release the key. Drag the field vertically.
Release handle and field: Drag horizontally to set the time it takes for the envelope
to fall from the sustain level to a level of zero. Drag the field vertically.
Vel slider: Set the intensity of filter envelope modulation in response to incoming
velocity data.
If the Vel slider is set to zero, the envelope outputs its maximum level when you
strike the keys at any velocity.
At a Vel slider value of 100%, the entire dynamic range is under velocity control.
