• Linear Crossfade: Sets the crossfade gain value behavior.
• Optimize Loop Start: Use to automatically adjust the loop start point to create a smooth
loop cycle.
• Optimize Loop Crossfade/End: Use to automatically set crossfade values at the point in
the loop cycle where the loop end and loop start markers cross over. Loop length is not
affected.
• Optimize Sample Gain: Analyzes the audio content and sets automatic gain values.
• Re-Analyze Transients and Tempo: Re-analyzes the current audio for transient and
tempo changes, following edits you have made.
• Reimport Optimized: Reimports the current audio with optimized tuning, loudness, and
length characteristics of the source file. Quick Sampler automatically adds loop and
crossfade markers to the waveform display for appropriate material and crops (cuts)
silence at the beginning or end of the source audio, shortening the imported content.
• Reimport Original: Reimports the current audio with the tuning, loudness, looping, and
length characteristics of the source file.
• Retune: Analyzes the audio content and sets the root key and tuning value
automatically.
• Write Sample Loop to Audio File: Saves the loop data to the file header of the audio file.
To save the new audio file with a different name, click the Name field and choose the
Rename Current Audio command.
Use slice markers to create new instruments and regions
In Logic Pro, you can use slice markers to create Drum Machine Designer tracks and to
create MIDI regions containing note-on events.
In the Slice mode waveform display, drag the slice handles to adjust existing transient and
start and end markers. You can also choose a number of commands from the Action and
shortcut menus. Control-click to access available options from the shortcut menu.
In Logic Pro, do any of the following:
• Click to the right of the start marker in the lower part of the waveform display, then:
Drag to a software instrument, Drummer, Drum Machine Designer, or MIDI track.
A curved arrow is shown to indicate the region can be dragged to a track. A new MIDI
region which contains note-on events that correspond to each slice between the start
and markers is created on the target track. You can edit these as you can any other MIDI
region.
