Voice Borrowing
(Pro Tools HD Only)
Pro Tools HD features voice borrowing , which lets
you assign more than one track to the same
voice. The track with the highest priority takes
over that voice, but when a hole opens up in the
higher-priority track, its shared voice is tempo-
rarily available, and the track with the next
highest priority “pops through” and begins to
play. When the original track returns, the track
that had popped through relinquishes the
shared voice to the higher priority track.
The following example demonstrates the con-
cept of voice borrowing:
In the above illustration, the two visible tracks
are assigned to the same voice. There is an open
area in the top track where no region appears. At
this point, the voice is free since it is not being
used, and the next highest priority track as-
signed to that voice (the bottom track) pops
through the open area and plays.
By experimenting with track priority, voice as-
signment, and arranging regions so that they are
positioned to “pop through” holes in higher pri-
ority tracks, you can find many useful ways to
maximize voiceable tracks with Pro Tools HD.
Setting MIDI Input and Output
MIDI recording and playback is supported with
MIDI tracks and Instrument tracks.
Assigning MIDI Track Input
Pro Tools lets you assign specific MIDI ports and
channels to a MIDI track input. The default se-
lection of All receives all incoming MIDI data
from all ports on all channels. Use the MIDI In-
put selector to specify a MIDI port and channel
for input.
To assign a MIDI track input:
■
Click the track’s MIDI Input selector and as-
sign a port and channel for MIDI input. Chan-
nels already assigned to another track appear in
bold.
“Rhythm” regions play when there is no “Lead” region
For information on assigning MIDI input to
Instrument tracks, see “Assigning MIDI In-
put and Output for Instrument Tracks” on
page 140.
In the Edit window, select View > Edit Win-
dow > I/O to access any track’s Input selec-
tor.
