MIX AUTOMATION
828
MIDI volume and pan automation
Digital Performer automates MIDI track volume
and pan using MIDI controller data (#7 for volume
and #10 for pan) to create sudden or smooth
volume changes, crossfade effects and panning
effects in MIDI tracks. MIDI volume controllers
have a range from zero to 127. Unlike note-on
velocities, which only affect the initial volume of
the note, volume controllers affect volume at any
time while a note is playing. Controllers can be
inserted, generated, drawn, reshaped, recorded
and otherwise handled using the Mixing Board,
Sequence Editor and MIDI Editor features
described in the rest of this chapter.

shown in both the MIDI Editor and the Event List.
Audio mix automation
Digital Performer provides continuous break-
point automation for all audio mixing parameters,
including volume, pan, and plug-in parameters.
Audio mix automation data can be inserted,
generated, drawn and reshaped. Unlike MIDI
events, which create discrete changes in MIDI
volume, audio automation events actually calculate
a smooth, sample-accurate ramp from one event to
the next. This effect is often referred to as “ramp”
automation because graphically, audio volume
events produce lines that ramp from one event to
the next, as shown below in Figure 71-2. Several
volume events can be used together to create
volume curves, as demonstrated by the bottom
track.
Figure 71-2: Digital Performer’s ramp automation features are
depicted as sloping lines connecting volume, pan and effects events
as shown here.
Pitch automation

time pitch automation layer, see chapter 81,
