Pro Tools
Sample-based program
 Sample-based internal MIDI resolution
of 960,00 pulses per quarter note (ppq)
 Tick-based internal MIDI resolution of
960 ticks per quarter note
 All tracks can be set to either sample
or tick-based.

Sample MIDI & Tick Audio

MIDI regions and
events within a
track will have an
absolute location on
the timeline.
 MIDI data stays
fixed to the sample
time, regardless of
tempo or meter
changes.

Audio regions will
be fixed to Bars
Beats, and they will
move more relative
to the sample
timeline with the
tempo and meter
changes.
Elastic Audio
Track-based Time Compression and
Expansion (TCE)
 Real-time or rendered
 Adds event markers to files for
conforming the audio to a tempo map
or quantize grid.
 Plug-in selector
 Track set to tick or sample-based

Elastic Audio Analysis

Waveforms will be temporarily grey while
P.T. analyzes, then will be online.
 If you analyze a sub-set region, the entire
underlying audio file will be analyzed.
 Detects transient events to calculate the
native tempo and duration of the file in bars
and beats.
 Analyzed files will have a check mark next to
their names (DigiBase browsers)
Tempo Detection
Any audio containing a regular periodic
rhythm can be analyzed for tempo.
 Treated as tick-based files - contain
timing information referenced to bars
and beats.
 These files can be conformed to the
session tempo for preview and import.
 No detected tempo? Sample-based
files

Event Confidence
Transient events are detected with
varying degrees of confidence.
 Based on relative clarity of the
transients
 Default event sensitivity of 100%
 You can adjust the event sensitivity to
filter out erroneous events.
 Add and relocate event markers

Plug-in Virtual Instruments
Real-time software plug-ins that run
within P.T. using a plug-in interface.
 RTAS or TDM plug-ins
 To monitor sound? Insert the plug-in
on an Auxiliary or Instrument track.
 Plug-in settings are saved with the
session
 Loaded automatically with Pro Tools
 High resolution automation functions

Available on all
systems: M-Powered,
LE and HD)
Rely on host
processing power
Takes up 2 additional
voices/channel.
May cause initial
latency on HD
systems.


TDM
Available on HD
systems only
Rely on TDM hardware
for processing
Not affected by host
CPU performance
Ideal for virtual
instruments.
Makes full use of the
DSP hardware, frees
up host processor.
Stand-alone Virtual Instruments

Software programs that run independently
from P.T. and connect via ReWire.
 No ReWire? Core Audio, WaveDrive, or
ASIO
 Monitor output?
– Through P.T. via ReWire
– Computer’s built-in sound capabilities
– Directly through Digidesign hardware
Synchronic




Instrument plug-in that manipulates rhythmic
audio loops by slicing, dicing, and
recombining audio.
Multi-effects processor that synchs to MIDI
Beat Clock to create in-tempo effects.
5 Modules: sound, playback, effect, Xfade,
and MIDI
12 presets
Load audio files into the sound module, does
not process sound on a track.
