MSS & AMS
Name and configure MIDI controllers,
devices and sound modules.
 Control their routing to Pro Tools
 MSS - Configurations can be imported
or exported.
 AMS - broadcasted to any applications
that support Apple’s Core MIDI.

Routing MIDI in Pro Tools

MIDI data from a control
source
MIDI/ Instrument track

MIDI data from Instrument or
MIDI track
sent to
a synthesizer

Audio from the synthesizer
Audio, Aux Input, or
Instrument track.
Track Abilities
MIDI & Instrument
Audio, Aux & Instr.
Record all types of
MIDI messages as
well as to route a
MIDI signal from a
controller or prerecorded MIDI file to
a MIDI instrument.
Are used to route the
audio signal from
the MIDI instrument
through the Pro
Tools system so it
can be processed
like other audio
signals.
Specific MIDI Routing
1.
MIDI Messages are generated from a MIDI
controller.
2.
MIDI signal enters the MIDI interface
3.
MIDI signal routed from MIDI interface to MIDI or
Instr. track (MIDI input selector).
4.
MIDI signal is recorded through the MIDI
instrument (MIDI output selector-external synth. or
virtual instr.).
I/O View & Comments View
I/O View
Contains tracks input and
output assignment,
track volume, and pan
settings.
Comments View
Displays comments that
have been entered for
a track.

Mix Window Track Width
Globally change the width of the
channel strips from the normal default
to a much narrower size.
 This allows you to view more tracks
simultaneously in the Mix window
= less scrolling

Hardware Buffer Size

Controls the number of samples
processed at once by our computer’s
CPU for host based tasks. = RTAS

Low setting = reduce monitoring
latency, use when recording live input.

High setting = more audio processing
tasks, mixing and using RTAS plug-ins.
RTAS Processors

Determines the number of processors in
your computer that are allocated to RTAS
plug-in processing.

Higher # of processors reserves more CPU
processing for RTAS plug-in processing
(with a high CPU usage limit).

Lower # of processor reserves more CPU
processing for automation, screen redraws
and video playback, or other applications.
CPU Usage Limit

Controls the percentage of CPU resources
allocated to P.T. host processing tasks.
 Lower limit useful for processing-intensive
tasks, or slow system response.
 Higher limit allows foro more processing
power to P.T. or playing back a large
sessions.


Single processor: 85%-99%
Half of available processors allocated to
RTAS processing 60-70%
RTAS Engine/Error
Suppression
1.
Continue playing and recording through
any RTAS errors encountered.
2.
Minimize additional latency caused by
suppressing RTAS errors during playback
and recording.

Use only if experiencing frequent RTAS
errors = degradation in audio quality
Disable RTAS error suppression during a
final mix = pops & clicks, yikes!!!

DAE Playback Buffer Size

Amount of memory allocated to buffering
audio being read from disk on your drive(s).

Low setting = improve system
responsiveness, less reliable recording.

High setting = improve performance for high
track counts, slow hard drives, can also
increase lag time initiating playback or
recording.
 Ideal size: 1500MS; Level 2
Cache Size

Amount of memory DAE allocates to prebuffer audio for playback and looping when
using Elastic Audio

Low setting - free up memory for other
system tasks, decrease in Elastic Audio
performance.

High setting - improves Elastic Audio
features, it also reduces the amount of
memory available for other systems tasks.
 Ideal size: Normal
Plug-In Streaming Buffer Size

Structure Plug-In Only

Amount of memory DAE allocates for
streaming playback from disk when
disk streaming is activated in
Structure’s engine settings page.

Optimum setting: 250MS; Level 2
Optimize the Streaming
Buffer Size

Structure plug-in only

Pro Tools automatically optimizes the size of
the Plug-In Streaming Buffer to facilitate disk
access from both P.T. and Structure.

This is useful when you are playing back
samples stored on the same drive that
contains audio for your session.
Pro Tools Hardware Settings

Default Sample Rate - change session
sample rate.

Clock Source and Optical Format - recording
from an external digital device.
