Note and Controller Chasing
Note Chasing
Note Chasing allows long, sustained MIDI notes
to be heard when playing from a point after
their start time. For example, if a note’s start
time is at 1|1|000 and lasts for 8 measures (until
9|1|000), note chasing lets you begin playing
from bar 5 and still hear the note that started at
1|1|000 as it continues to sustain until 9|1|000.
Note Chasing is something that can turned on
and off individually for each MIDI track. By de-
fault, new MIDI tracks have Note Chasing en-
abled.
To enable Note Chasing for a MIDI track:
■ Click the track’s Playlist Selector and select
the option for Note Chasing.
Make sure to disable Note Chasing when work-
ing with samplers that are playing loops. If a
MIDI track, for example, is triggering a 4-bar
drum loop and you begin playing at bar 3, the
loop will begin playing at the wrong time and be
out of sync with the other tracks.
Controller and Program Chasing
Pro Tools always chases continuous controller
events and program changes for MIDI tracks.
This ensures that controller values and patches
for MIDI devices are always appropriately set.
For example, suppose a MIDI track lasting 32
measures starts with a volume of 127 and in the
last bar fades the volume down to 0. If after
playing the track in its entirety you attempt to
play from bar 8, the initial volume of 127 is
chased and sent to the track’s assigned device—
otherwise the track would not be heard since the
most recent volume event sent would have
been 0.
Chasing also occurs for a MIDI track’s default
program change, along with any program
change events residing within the track. There-
fore, if you have chosen a default program
change for a track, when playing from any point
within the track, the program change event is
sent to the track’s assigned device.
Individual Sysex event blocks can also be
deleted by Alt-clicking (Windows) or Op-
tion-clicking (Macintosh) them with the
Pencil.
