Merging MIDI Regions
You can merge two or more selected MIDI Regions into a single MIDI Region, by
clicking on one of them with the Glue tool (see “The Tools” on page 18).
The function of the Glue tool is the same as Region > Merge > Regions. This merges all
selected MIDI Regions—even those on different tracks—into a single MIDI Region. All
events from each individual MIDI Region retain their original time positions. Be aware
that the individual MIDI channels are replaced by the MIDI channel of the current
track’s Instrument. The new (merged) MIDI Region adopts the name and track of the
first (along the time line) of the merged MIDI Regions (see “Fixing/Neutralizing MIDI
Region Parameters” on page 120).
The Region > Merge > Regions per Tracks function has the same effect as Merge Regions,
but if the selected Regions are on several different tracks they are combined into one
Region per track.
The Region > Merge > Regions, the Region > Merge > Regions per Tracks and the Glue tool
functions handle the Transpose, Velocity, and Dynamics Region parameters intelligently.
If these parameters are not identical in all selected Regions, the Regions are normalized
before the merge. If one of the Region parameters (the Transpose value, for example) is
set identically in all selected Regions, that value is preserved, and the events remain
unchanged.
Demixing Regions
The Region > Split/Demix > Demix by Event Channel function searches the selected
Region for events with different MIDI channels. A separate 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 that matches the MIDI channel. If no such
tracks exist, new tracks are created, using the original Instrument’s track.
This function is useful for the import of Standard MIDI Files (Format 0), when all note
events are placed in a single MIDI Region.
The Region > Split/Demix > Demix by Note Pitch function searches the selected MIDI
Region for notes with different note numbers. A different MIDI Region of the same
length is created for every note number found. The tracks created for these MIDI
Regions is assigned to the same Instrument as the original MIDI Region. This feature is
especially useful for separating drum parts that have been recorded into Logic from a
drum machine.
