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

Record all types of MIDI messages as well as to route a MIDI signal from a controller or pre-

recorded MIDI file to a MIDI instrument.

Audio, Aux & Instr.

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.).

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 scrollingview > narrow mix or…Command+option+M

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 pre-

buffer 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.
