Logic Pro Auto Sampler controls and parameters
The following lists the Auto Sampler controls, with brief descriptions of their functions.
• Range Start field and slider: Drag vertically to set the lowest note of the key range.
You can also drag the left Sample Note Range handle in the keyboard display.
• Range End field and slider: Drag vertically to set the highest note of the key range.
You can also drag the right Sample Note Range handle in the keyboard display.
• Sample Every field and slider: Drag vertically to set the interval between sampled notes
in semitones.
• Round Robin pop-up menu: Choose the number of times each sample is captured to
provide sound variations for more realistic sample playback (if the source provides
sound variations). Choose No to capture each sample only a single time (no round
robin).
• Sustain field and slider: Drag vertically to set the duration that the note is sampled
(before its release phase begins) in seconds. Percussion and other short-duration
sounds are shortened after sampling if the end contains complete silence.
For notes (pitched sounds), a Sustain value of 10 seconds or more is recommended.
• Velocity Layers pop-up menu: Choose the number of velocity layers to sample. The
default is 1. To sample multiple velocity layers, the source instrument must respond
to MIDI Velocity as well as MIDI Note messages.
• Velocity Response pop-up menu: When multiple velocity layers are sampled, choose a
velocity response curve:
• Linear: Divides the Velocity span region equally. This is the default, and is
recommended for most situations.
• Exp1-Exp3: Gradually render the Velocity curve more exponentially. After the Velocity
high and low parameters are set, more zones are sampled next to the High Velocity
setting. This results in more zones with smaller Velocity spans, and lower Velocity
zones that span more Velocity values.
• Log1-Log3: Gradually render the Velocity curve more logarithmically. After the
Velocity high and low parameters are set, more zones are sampled next to the Low
Velocity setting. This results in more zones with smaller Velocity spans, and higher
Velocity zones that span more Velocity values.
• Velocity Editor: You can view and edit velocity layers in the Velocity editor. When you
hold the pointer over the Velocity Layers and Velocity Response pop-up menus, the
Velocity editor appears in the lower part of the window. Each velocity layer appears
as a horizontal line, with its velocity value displayed. You can drag lines vertically to
adjust their velocity value. When you manually adjust velocity layers in the Velocity
editor, the Velocity Response value changes to Custom.
