MIDI region parameters
The following parameters are available for MIDI regions (and software instrument Apple Loops)
in the Region inspector.
The MIDI region parameters also apply to folders, and globally affect all MIDI regions within
the folder.
•
Transposition: All note events contained in the MIDI region are transposed up or down by the
selected amount during playback. Even complete folders can be instantly transposed in this
way. If several individual MIDI regions within the folder have already been transposed, the
relative differences between them are retained.
If you want to transpose by octaves, click the arrows to the right of the Transposition
parameter. A pop-up menu opens that allows direct octave transpositions.
To guard against drum notes and so on being transposed, an instrument channel’s inspector
contains a No Transpose checkbox. If you select this option, the Transpose parameter is
ignored in all MIDI regions played by this channel strip (including instrument Apple Loops
added to tracks routed to instrument channels).
•
Velocity: All notes in the relevant MIDI region are offset by the selected value. Positive values
add to the originally recorded velocity, and negative ones subtract from it, although naturally
it is impossible to go outside the limits defined by the MIDI Standard (0–127). If you select a
velocity offset that exceeds the maximum or minimum possible value for a particular note,
that note will play at the extreme possible range. For example, a setting of +20 will cause a
note with a velocity of 120 to play at 127.
•
Dynamics: This parameter also affects the velocity values of notes, but instead of adding or
subtracting a fixed amount, the differences between soft and loud notes (the dynamics) are
increased or decreased. This works in a similar way to a compressor or expander. Values above
100% expand the dynamics, thereby increasing the difference between loud and soft, while
values below 100% compress the dynamics, reducing the differences between loud and soft.
The Fixed setting causes all notes to be transmitted at a velocity value of 64. When used
in conjunction with the Velocity parameter (see above), it’s possible to set any fixed
velocity value.
•
Gate Time: The term gate time stems from analog synthesizers, and refers to the time between
pressing and releasing a key. This parameter affects the absolute note duration or length,
which can be different from the musical note value. The practical effect is to make notes in the
region more staccato or legato. The parameter range is related to the original note lengths.
Fix produces extreme staccato. Values below 100% shorten the notes. Values above 100%
lengthen the notes. The “legato” setting produces a completely legato effect for all notes, no
matter what their original lengths, eliminating all space between notes in the affected region.
•
Clip Length: This function lets you alter the length of the last notes in a region directly from the
Tracks area, by adjusting the length of the MIDI region. When turned on, any notes sounding
when the region ends are abruptly cut off. When turned off, notes are played to their normal
end point, regardless of where the region ends.
•
Score: The point of this function is mainly to prevent the score display of particular regions—
namely those that only contain MIDI events that can’t be displayed in the score, such as
controller or SysEx data. When turned off, the MIDI region is not displayed in the score at all.
•
Advanced Quantization: Q-Flam: Notes with the same time position (chords) are spread out
by this parameter. Positive values produce an ascending (upward) arpeggio; negative values
a descending (downward) arpeggio. The position of the first note (either the bottom or top
note, assuming all notes start at the same position) in the arpeggio is unaltered.
