Inserting/Editing Controller
Events
Continuous controller events can be edited
with any of the following methods:
◆ Individual breakpoints can be dragged
with the Grabber to adjust their location or
value.
◆ A group of selected breakpoints can be
scaled up or down with the Trimmer.
◆ New controller events can be drawn in
with the Pencil tool to replace existing
events. Events can be drawn with the Pen-
cil set to Freehand, or using any of the
shapes (Line, Triangle, Square, or Random).
◆ Controller events can be copied and
pasted, nudged, and shifted.
For details on these editing procedures, see
Chapter 21: Automation.
✽ Edits to volume data affect all tracks within
an enabled Edit Group. This is not the case,
however, for other controller playlists (such as
pan). To insert and edit other controller types
across all tracks in an Edit Group, press Con-
trol (Macintosh) or the Start key (Windows)
while performing the edits.
Resolution for Inserted Controller
Events
When inserting controller events with the
Pencil, the density of the events is deter-
mined by the MIDI Preference for “Pencil
Tool Resolution When Drawing Controller
Data.”
To set the Pencil tool resolution:
1 Choose Setups > Preferences and click
MIDI.
2 Enter a value for “Pencil Tool Resolution
When Drawing Controller Data.” The
value range is from 1 to 100 milliseconds.
3 Click OK.
Program Changes
Each MIDI track can have a default pro-
gram change that is sent each time the
track plays. Additional program changes
can be inserted at any point within the
track.
About Program and Bank Changes
The MIDI protocol lets you choose from a
range of 128 programs (0-127). Most MIDI
instruments have several banks of 128 pro-
grams. To specify which bank you’re select-
ing from, a bank select message must be
sent. Some instruments use Controller 0 to
switch the bank while others use Control-
ler 32 (some use a combination of the two).
The Program Change window in Pro Tools
allows you to use either of these bank select
messages when inserting a program change
event. Check with the manufacturer’s doc-
umentation to see which message your de-
vice uses.
✽ Some older MIDI devices (such as the Kurz-
weil K1000) use a program change instead of
a Bank Select message to switch banks. For
these devices you may find it necessary to
send two program change messages to ac-
cess a particular program, where the first sets
the bank and the second sets the program.
