Audio Crossfades in Digital Mixdown
The Digital Mixdown supports crossfades between selected regions.
The crossfade parameters are defined in the General Audio preferences tab, which can
be opened either by choosing Logic Express > Preferences > Audio > General (or the
Audio Crossfade Options for Merge key command).
There are two faders:
 Crossfade Time [ms]: This is the length of the entire crossfade. To switch off the
crossfade, set this value to zero.
 Crossfade Curve: To obtain a linear crossfade, set this value to zero. Other values
(positive or negative), produce various exponential fades. The fade-outs and fade-ins
are always symmetrical, to avoid deviations in level. The preset values are: Time =
0 ms, Curve = 0 (linear).
Demixing MIDI Regions
You can split MIDI regions (or Standard MIDI File Formats 1 or 0) by event channels or
note pitches.
To split MIDI regions by event channels:
1 Select the desired MIDI regions.
2 Choose Region > Split/Demix > Demix by Event Channel (or use the corresponding key
command)
Logic Express searches the selected MIDI regions for events with different MIDI
channels.
 A separate MIDI region, containing all matching events, is created for every MIDI
channel that is found.
 Each of these regions is created on a track with an instrument channel that matches
the MIDI channel.
 If no such tracks exist, new tracks are created for each channel.
