• Coarse Tune Remote pop-up menu: Choose a note value that sets the center key for
keyboard-controlled transposition. The range is an octave above and below this key.
Play a note in this range to transpose the mapping in semitones. This is much like using
the Tune parameter.
• Transpose field: Use to transpose the MIDI input value in semitone increments.
• Sample Select Random field: Set the range of randomization values for Sample Select
modulation. This is useful for instruments with multiple layered zones as it can emulate
the subtle tonal fluctuations caused by changes in playing technique. You can also use
it to switch wildly between samples for more extreme sonic results.
• Velocity Random field: Set the range of randomization values for velocity modulation.
This is useful for emulating tonal variations in instruments when played, struck, or blown
at different levels.
• Amp Velocity Curve field: Use to determine how Sampler responds to incoming velocity
values. Negative values increase the responsiveness to soft key strikes, and positive
values decrease responsiveness.
• Velocity Offset field: Use to increase or decrease incoming MIDI note velocity values,
expanding or limiting the dynamic response to MIDI note events.
• Ignore Release Velocity button: Turn on to play samples at a note-off velocity level that
is equal to the note-on velocity level. Turn off to control the note-off velocity level with
a suitably-equipped MIDI keyboard. If your keyboard cannot send note-off velocity data,
Logic Pro ignores the Ignore Release Velocity setting, and the note-off velocity level is
always equal to the note-on velocity level.
Note: This parameter applies to the release trigger function of the Gigasampler format,
and should be turned on for this purpose.
• Amp Key Scale field: Set the amount of level modulation by keyboard position. Negative
values increase the level of lower notes. Positive values increase the level of higher
notes. This is useful when you are emulating a number of acoustic instruments, where
lower-pitched notes are often louder than high notes.
• Polyphony field: Set the maximum number of keys that can be played simultaneously.
See Use Sampler Unison, Mode, and Polyphony parameters.
• Mode pop-up menu: Switch between legato, monophonic, and polyphonic behaviors.
• Unison pop-up menu: Set the number of unison voices or turn unison mode off.
• Random Detune field: Set the amount of random detuning applied to each voice. Use
this parameter to simulate the tuning drift of analog synthesizers or to thicken the
sound. Random Detune is also effective when you are emulating various stringed
instruments.
• Used Voices field: Shows the number of playing voices in real time.
Use Sampler Unison, Mode, and Polyphony parameters
You will find all parameters discussed in this section in the Synth Details slide-out pane.
Click the Details button at the top-right of the Synth pane if it is not visible.
In Unison mode, multiple voices are played when you play a key. You can use this to
achieve a richer sound, particularly when you also use the Random Detune parameter
to slightly detune each voice. This is ideal when you are emulating classic analog
synthesizers, and is also useful for stringed instruments.
