In this example, the maximum velocity range value of zone 121 and the minimum velocity
range value of zone 122 are adjacent. If you play note D1 at velocities above or below a
value of 51, you can clearly hear each sample being triggered.
To make this transition less abrupt, you can expand the velocity range of these zones by
applying a crossfade value to the Sustain pedal #1 group. Each layered zone within this
group will be crossfaded by the Xfade amount you set. The crossfade takes place in the
extended velocity range area.
In Group view, do the following for the Sustain pedal #1 group:
• Click the Mapping button in the Navigation bar, then click the Group view button.
• Click the Sustain pedal #1 group in the Name column.
• Scroll to the Velocity Range column, and set values for these parameter subcolumns.
• Low field: Set the lowest velocity that triggers the group. For zone 121 this would
be a value of zero.
• High field: Set the highest velocity that triggers the group. For zone 122 this
would be a value of 80.
• XFade field: Set the crossfade range for zones grouped by the specified velocity
range. Only zones within the specified velocity range are crossfaded.
• XFade Type pop-up menu: Choose the crossfade type that best suits the group
audio material. The Linear dB and Linear Gain options scale the amplitude for the
group crossfade. Equal Power applies an exponential crossfade curve that causes
a volume boost of 3dB in the middle of the crossfade range. This fades out/fades
in at an equal volume level.
Note: The settings made here override zone settings.When a zone velocity range is
larger than the group setting, the zone velocity range is limited by the group velocity
range setting.
Smoothly crossfade between groups in real time with a modulator
In Logic Pro Sampler, you can use a continuous modulation source, such as the modulation
wheel, assigned to the Sample Select target to switch between layered samples—in groups
with different velocity or key ranges. Adjust the crossfade amount to achieve smooth
transitions between groups.
In an instrument that contains different samples mapped to several groups with different
velocity (or key range) layers:
1. In the Mod Matrix pane, choose Sample Select from the Target pop-up menu in a
modulation routing.
2. In the Mod Matrix pane, choose a modulation source from the Source pop-up menu,
such as MIDI controller 1, the modulation wheel.
