76 MIDI Effects Processing
OVERVIEW
Digital Performer provides many real-time, non-
destructive MIDI effects plug-ins. This chapter
discusses the specifics of each MIDI plug-in.
For general information about the Effects window,
see chapter 74, “Effects Window” (page 867). For
general information about using plug-ins,
organizing them, creating and managing user
presets, and other related topics, see chapter 75,
“Audio Effects Processing” (page 873).

CHANGE DURATION
The Change Duration plug-in can non-
destructively modify the durations of MIDI notes
during playback. It has the same settings as the
Change Duration command in the Region menu
(page 601).
Figure 76-1: The Change Duration effects processor.
Change Duration modifies the duration without
changing the placement of attack times. This
means that the amount of time a note is “on” or
sounding can be changed without affecting its
actual rhythmic placement in relation to other
notes and events. The Change Duration command
is useful for changing the articulation or space
between notes. You can make note events sound
connected or separate in relation to each other, for
example. It also provides some useful utility
functions.
For more information, see “Change Duration” on
page 601.
CHANGE VELOCITY
The Change Velocity plug-in can non-destructively
modify the on and/or off velocities of MIDI notes
during playback. It has the same settings as the
Change Velocity command in the Region menu
(page 598).
For the Compress/Expand option, the graph shows
the result of the compression/expansion settings. A
diagonal line from lower left to upper right
represents no compression or expansion. Drag the
Threshold, Ratio and Gain handles to change their
settings. The higher the ratio, the higher
compression; ratios below 1 produce expansion.
Gain allows you to raise or lower the overall level.
Threshold sets a cutoff value, below which no
compression or expansion will occur.
