Sampler Synth Details in MainStage

You can use the Synth and Synth Details parameters to affect the overall behavior of the loaded instrument. If you’re new to the concepts and use of synthesizers and samplers, see Synthesizer basics overview.

Click the Details button to view or hide the Synth Details slide-out pane.

Drag vertically in parameter value fields to change them.
Option-click a parameter value to reset it to the default value.
Double-click a parameter value field to enter a new value. Press Enter to complete the operation.

Synth Details parameters

Glide field: Set the time it takes to slide from one note pitch to another—the portamento time.
Note: In Legato mode, Glide is active only on tied notes and envelopes are not retriggered when tied notes are played. In other words, playing a series of tied notes results in only a single envelope trigger. In Mono mode, Glide is always active and the envelopes are retriggered by every note played. See Use Sampler Unison, Mode, and Polyphony parameters.
Pitch Bend Up/Down pop-up menus: Set the upper and lower limit of pitch bends in semitones. A value of 0 disables pitch bends.
Note: When you choose Linked in the Pitch Bend Down pop-up menu, the bend range is identical in both directions. For example, if you assign an upward bend of 4 semitones, the downward bend is also set to 4 semitones, resulting in a combined bend range of 8 semitones (9, if you include the standard pitch, or no bend position).
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.
