Quick Sampler Pitch controls in Logic Pro for Mac
Quick Sampler Pitch controls affect the playback pitch behavior of the current audio file. You can control pitch over time with a dedicated multimode envelope. Parameters that are modulation targets are indicated by a white dot when a note is played. The modulation range is shown as an orange ring around target parameters.

Quick Sampler Pitch parameters
Coarse knob and field: Tune the instrument in semitone steps.
Fine knob and field: Tune the instrument in cents. One cent is 1/100 of a semitone.
Glide knob and field: Set the amount of time it takes to slide between the pitches of each played note.
Env Depth knob and field: Set the amount of envelope modulation.
Key Tracking button: Turn on to change the pitch and speed of sample playback when different notes are played. Turn off to play the sample at the original pitch and speed when any key is struck.
Bend Range pop-up menu: Set the pitch bend range in semitones.
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. The envelope types shown are abbreviations for the controls in the envelope shape: AR is an envelope that provides Attack and Release controls. AHDSR provides Attack, Hold, Decay, Sustain, and Release parameters.
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 pitch 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.
To explain, raising the slider value reduces the envelope minimum amplitude, with the difference being dynamically controlled by keyboard velocity. For example, when you set the Vel slider to 25%, the minimum envelope amplitude is reduced to 75%. The remaining 25% is added in response to the velocities of keys you play. A key played with a zero velocity results in an envelope amplitude of 75%. A key played with a MIDI velocity value of 127 will result in an envelope amplitude of 100%. When you raise the Vel slider value, the minimum amplitude decreases even further.
