Quick Sampler Pitch controls in Logic Pro for iPad

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.

Tap the pitch envelope display to open the Pitch edit pane. You can drag points or lines in the pane to adjust envelope parameter values. Alternatively, in envelope parameter fields, drag values vertically to adjust them, or tap the field to open a dialog and enter values.

Tap Close at the top right of the edit pane to close it.

You can quickly switch between the Pitch, Filter, and Amp edit panes with the pop-up menu at the top left.

Quick Sampler Pitch parameters

Tune knob and field: Tune the instrument in semitone steps.
Fine Tune knob and field: Tune the instrument in cents. One cent is 1/100 of a semitone.
Glide Time knob and field: Set the amount of time it takes to slide between the pitches of each played note.
Depth knob and field: Set the amount of envelope modulation.
Pitch Bend (Up) pop-up menu: Set the pitch bend range in semitones.
Key Track 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.
Pitch envelope display: Shows the current pitch envelope. Tap to open the Pitch edit pane.

Quick Sampler Pitch Envelope parameters

Type pop-up menu: Choose the pitch 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: AD is an envelope that provides Attack and Decay controls. AR is an envelope that provides Attack and Release controls. ADSR provides Attack, Decay, Sustain, and Release parameters. AHDSR provides Attack, Hold, Decay, Sustain, and Release parameters.
- Pitch Envelope Attack handle and field: Drag horizontally to set the time it takes for the envelope to reach the initial level. Drag the field vertically.
- Pitch Envelope 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.
- Pitch Envelope 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.
- Pitch Envelope Sustain handle and field: Drag vertically to set the sustain level, which is held until you release the key. Drag the field vertically.
- Pitch Envelope 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.
Pitch Envelope Velocity slider: Set the intensity of pitch envelope modulation in response to incoming velocity data.
- If the Velocity slider is set to zero, the envelope outputs its maximum level when you strike the keys at any velocity.
- At a Velocity 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 Velocity 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 Velocity slider value, the minimum amplitude decreases even further.
