Chapter 2: Macintosh Conﬁguration 11

Hard Drive Requirements

For audio recording and storage on the Macintosh, Pro Tools LE requires one or more qualiﬁed ATA/IDE or SCSI drives with the following properties:

• Formatted with HFS or HFS+ ﬁle system

• Data transfer rates of 3 MB per second or faster

• Drive spin speed of 7,200 RPM or faster

• Average seek time of 10.0 milliseconds or faster

✽

For the latest compatibility information on hard drives, visit the Digidesign Web site (www.digidesign.com).

Using System Drives for Audio

Although Pro Tools will let you record to your system drive, this is generally not recommended. Performance for recording and playback on system hard drives is worse than on non-system drives, resulting in lower track counts and fewer plug-ins.

You should record to system drives only when absolutely necessary—if your computer system has just one hard drive, or if your other hard drives are completely out of space.

SCSI Hard Drives

SCSI hard drives offer several advantages over ATA/IDE drives. First, SCSI drives can be external and therefore provide portable audio storage that is easily moved between systems. Second, SCSI drives offer slightly better performance when recording to large numbers of tracks; attempting to record to a large number of audio tracks with an ATA/IDE drive will result in a short delay before recording begins.

Initialize and Defragmenting Drives

It’s recommended that you start with a newly initialized audio drive. You should also periodically

If you are using a SCSI hard drive, you can use the (included on the Pro Tools LE Installer CD) to initialize and defragment the drive.

If you are using an ATA/IDE hard drive, use the System software.

Digital Audio

Digital audio represents analog waveforms using thousands of digital samples of the analog waveforms each second. All audio on your hard disk in a Pro Tools LE session is digital audio.

Digi 001 provides digital inputs for ADAT and S/PDIF format digital audio.

ADAT Format

The ADAT format was developed by Alesis for use in their ADAT multitrack recorders. Each ADAT optical connection provides 8 channels of digital audio with 24-bit capability. You can connect an ADAT or other ADAT optical format device directly to the optical I/O on the Digi 001 PCI Card. The optical I/O connectors accept optical cables.

S/PDIF

S/PDIF (Sony/Phillips Digital Interchange Format) I/O is available on many DAT decks, compact disc players, and other digital devices. Each S/PDIF connection provides 2 channels of digital audio with 24-bit capability. You can connect a S/PDIF digital input to either the Optical connectors (see Figure 1), or to the S/PDIF RCA connectors on the back of the Digi 001 I/O Box. The optical connectors accept optical cables; the RCA connectors accept RCA cables.

Chapter 4: Connecting Your Studio 33

S/PDIF Mirroring

Pro Tools LE uses S/PDIF mirroring to automatically “mirror” the audio that is sent to outputs 1 and 2 on the S/PDIF RCA outputs. This is useful if you are monitoring a mix using your audio outputs, and also recording the same source to an external S/PDIF device.

You can disable this S/PDIF mirroring. You might do this if you wanted to use the S/PDIF outs to send a separate signal to an external digital effects unit, or if you wanted to send only certain outputs to the digital device. If you disable S/PDIF mirroring you are able to select the S/PDIF outputs separately, and route tracks or sends to them.

To enable or disable S/PDIF mirroring:

1 Choose Setups > Playback Engine. 2 Click Other Options. 3 Select or deselect the option “Enable S/PDIF Mirroring.”

Connecting Audio Sources

To connect an analog audio source:

■ Plug a microphone directly into Mic/Line Input 1 or 2 on the front of the Digi 001 I/O

Box. These inputs accept XLR connectors or 1/4" TRS connectors. If your microphone requires phantom power, press the Phantom Power switch (labeled 48V).

▲ Although phantom power can be used safely with most microphones, ribbon mi-

crophones can be destroyed by it. You should always turn off phantom power, and wait for the red light to go completely off, before connecting a ribbon microphone.

■ Plug line-level sources (synths, outputs from your mixer, or microphones or guitars that

have been ampliﬁed by an outboard preamp) into the analog inputs on the back of the Digi 001 I/O Box.

Using standard 5-pin MIDI cables, connect the MIDI OUT of the MIDI device or controller to the MIDI IN of your Digi 001 I/O Box.

Connect the MIDI IN of your MIDI device or controller to the MIDI OUT of the Digi 001

I/O Box.

Connect the audio outputs of your device to the audio inputs of the Digi 001 I/O Box (or

to an external mixer if you are using one).

Pro Tools MIDI Controllers Guide

Using External Effects Devices

The Digi 001 allows you to create dedicated connections to external analog or digital devices. You can send and return signals to analog devices using the analog inputs and outputs on the Digi 001 I/O Box. You can also send and return a digital signal to an external device that supports digital I/O (such as a reverb unit), and monitor with the analog outputs or (if unused) the other digital output.

If you want to use the digital inputs and outputs on your Pro Tools LE system as effects sends and returns to a digital effects device, Pro Tools LE should be the clock master in most cases. Set your digital effects device to accept an external digital clock so that it synchronizes to Pro Tools LE.

Chapter 4: Connecting Your Studio 41

To connect an external device to your system:

Connect an unused output (or outputs if stereo) on the Digi 001 I/O Box to an input (or inputs if stereo) of the external signal processor.

Connect the output (or outputs if stereo) of the external signal processor to an unused

input (or pair of inputs if stereo) on the Digi 001 I/O Box.

To set up a send to an external device (digital sends/returns only):

Choose Setups > Playback Engine and click Other Options.

Do one of the following:

• If the external device is connected to the S/PDIF RCA jacks, deselect S/PDIF Mirroring. (When S/PDIF Mirroring is on, digital output at the S/PDIF RCA jacks exactly mirrors the output of analog Channels 1–2.) If you disable S/PDIF Mirroring, you must reset I/O labels to reﬂect this change. See “Resetting Hardware I/O Labels” on page 42.

• If the external device is connected to the Optical ports, choose a format (most likely S/PDIF for an effects device) from the Optical Format pop-up menu.

Choose Internal from the Sync Mode pop-up menu (in most cases).

Click OK.

You can also label the inputs and outputs you are using in Pro Tools LE to quickly identify them as inserts or sends when working in a session.

To label hardware I/O Inserts or Sends:

Choose Setups > I/O Labels.

Under Display, click Inputs (for hardware inserts), or Outputs (for hardware sends) and

name the connections carrying signal to or from the external device (for example,

ReverbSend.L and ReverbSend.R or Reverb Return.L and Reverb Return.R ).

When you have ﬁnished, click OK.

Resetting Hardware I/O Labels

If you make a change to the number or type of inputs and outputs you are using (for example, if you turn S/PDIF Mirroring on or off, or you switch the Optical input format from ADAT to S/PDIF), you may want to update the I/O labels. This helps you keep track of which inputs and outputs are available, and what they are named.

To reset hardware I/O labels:

Choose Setups > I/O Labels.

Select Inputs, and click Factory Reset.

Select Outputs, and click Factory Reset.

Click OK when you are done.

Mixing the Demo Session Tutorial

Now it’s time to start mixing audio in Pro Tools LE.

But first, a common question answered for you:

Can I ruin my recording?

When you edit and mix audio in a session, you don’t actually change the underlying audio ﬁles. So even with many different sessions based on the same audio ﬁles, with different mixes and arrangements, your audio ﬁles remain physically unchanged. You don't lose your valuable recordings when you change your mix or save a different session, and you can freely try arrangements and ideas.

The Pro Tools LE Workspace

Pro Tools LE provides two main windows for visual display of your tracks—the Mix window and the Edit window. We’ll start working with the Mix window, and later we’ll work in the Edit window.

The Mix window looks and operates like a hardware mixer with automation. Each track is represented as a channel strip. Channel strips have controls for volume, panning, automation, inserts and sends, recording, and more.

To make a normal-width Mix window narrow, or a narrow Mix window normal-width:

■ Select or deselect Display > Narrow Mix Window.

Chapter 5: Working with the Demo Session 49

All Right, Let’s Mix!

Now that you’ve been introduced to some elements of the Mix window, it’s time to dive in and start mixing the demo session.

Adjusting the Volume of a Track

First, adjust the volume of the track called “loop1.” Start by clicking the Memory Location “Loop 1 Vol + Pan” in the Memory Locations window. Play the session and view the Mix window, then adjust the volume of the track labeled “loop1” up and down, and listen to the difference in the mix. The volume is indicated on the track’s Volume indicator.

To adjust the volume of a track:

1 Locate the proper tutorial spot by clicking “Loop 1 Vol + Pan” in the Memory Locations

window. Now only the channel strip labeled “loop1” and the Master Fader channel strip are showing.

2 Click the Volume fader on the “loop1” channel strip and move it up or down to increase

or decrease volume.

Mix Automation

Automation is a way to control the movements of faders, sliders, and other controls of the Pro Tools LE mixer, and to have the controls remember the moves you’ve made when you play back the session. You can think of automation like a person with a lot of hands and a perfect memory “riding” the controls during a mix.

Writing Your Own Automation

Let’s write some automation for the guitars. Click the Memory Location “Guitar Vol Auto,” and click Play in the Transport window. In preparation for your work here, some tracks are muted so you can easily hear how the guitars mix with the bass and drums. First, try mixing the guitar volumes like you mixed the volume for “loop1,”and notice how each volume fader moves back to its original position after you let it go.

Starting with the track “cleangtr,” set the Automation Mode to Auto Write, then move the volume fader during playback to write volume automation. To hear the automation, switch back to Auto Read mode. Then do the same thing for the track “dirty1.”

Chapter 5: Working with the Demo Session 51

To write automation:

1 Click “Guitar Vol Auto” in the Memory Locations window to go to the tutorial location. 2 On the track “cleangtr,” click the Automation Mode button and choose Auto Write for

the Automation Mode.

3 Click Play in the Transport window. Automation begins writing for the track you have

selected. Move the Volume fader to write changes to the automation.

4 When you have ﬁnished writing automation, click Stop.

select Auto Write for

the Automation Mode

To play back automation:

1 Set the Automation Mode on the “cleangtr” track back to Auto Read. Now your

automation will be read as the track is played back.

2 Play the song. Your automation is played back as the song plays. The Volume fader in the

Mix window also moves as the song plays back, displaying your automation.

Now write volume automation for the distorted guitar track “dirty1,” using the same steps.

Mixing in the Edit Window

The Edit window can be used for many editing tasks, and it also allows you to “draw” very precise Mix automation. First, we’ll use the Edit window to expand on the automation we wrote in the Mix window by drawing a precise fade-out on the Master Fader at the end of the song.

Digi 001 Quick Start Guide52

Drawing Automation in the Edit Window

In the Edit window, you can view different data for a track, including a representation of the actual waveform, and volume, mute, and pan automation. In this example, we’ll view the Master Fader, which controls the volume of the overall mix, and fade out the end of the song to silence. Try fading out from the start of the last chorus.

To draw a volume fade in the Edit window:

1 First, click the Memory Location “Out Vamp.” Then switch to the Edit window by

choosing Windows > Show Edit.

2 Next, make the track height larger for the Master Fader track (this is shown at the bottom

of the following illustration). This will make it easier for you to draw the fade.

Plug-Ins

Pro Tools LE provides a collection of Real Time AudioSuite (RTAS) Plug-Ins that can be used to process audio tracks. RTAS Plug-Ins are provided for common effects such as equalization, compression, and delay.

Using Plug-Ins

Plug-ins are placed in a track insert. An insert, as its name implies, is used to insert something in the audio path of a track before you hear it. For example, an insert can be used to place a compressor in a track, and compress the audio before it reaches the audio outputs.

You can easily add a plug-in by clicking a free insert on a track, and choosing a plug-in from the pop-up menu. You can do this during playback or when playback is stopped. Note that you can add several different instances of a plug-in in the same session, depending on your CPU’s power. For example, the demo session uses the 4-band EQ Plug-In 3 times. Once you add a plug-in to an insert, you can open it to view and adjust settings by clicking on the plug-in name next to the insert.

Digi 001 Quick Start Guide54

Plug-Ins: click on to view and change settings

Several plug-ins are already activated in the demo session “Be There.” We’ll try adjusting the EQ Plug-In on the track called “VOX.” First, you’ll have to ﬁnd a good location to hear the vocals. We’ll start at the ﬁrst verse. But since the “VOX” track isn’t showing, we’ll have to show it ﬁrst by clicking it in the Tracks list on the left of the Mix window.

To change plug-in settings:

1 Show the Mix window by choosing Windows > Show Mix. Click the Memory Location

“Verse 1.”

2 To show the vocal track, click “VOX” in the Show/Hide Tracks List.

Cool Mix Tricks: The Big Mute

Now that you’ve started mixing with Pro Tools LE—and you haven’t had this much fun in years — here’s a really cool thing you can do. We call this The Big Mute, and it’s one of those tricks you hear often in popular songs of any genre. The Big Mute is basically an automated mute across a bunch of tracks used to highlight a small section of the song. We’ll write this mixing “move” as mute automation across all those tracks using an automation group that’s already set up.

✽ To understand this trick better, you can refer to the information on Mix Automa-

tion and the information on Groups in the going to give away all the tricks in this Quick Start Guide—we just want you to have an idea of what’s possible with Pro Tools LE.

To automate The Big Mute:

1 Go to the tutorial location by clicking “Big Mute” in the Memory Locations window. 2 Enable the Big Mute group by clicking “Big Mute” in the Groups list.

3 Set the Automation Mode to Auto Write on the slap return track, called “SlpRt,” by

group to enable

clicking the Automation Mode button and selecting Auto Write from the pop-up. This will enable you to automate the muting of the slap return track, which puts a delay on the lead vocal.

4 Click Play in the Transport window, and click Mute on the track to begin writing mute

automation.

Chapter 5: Working with the Demo Session 57

5 Click Mute again to stop writing Mute Automation before the lead vocal begins the

second part of the chorus (before but when she comes around).

6 Click Stop in the Transport window to stop writing automation.

✽ The Automation Mode automatically switches to “Auto Touch” after you stop

playback. This Automation Mode, which is used to “touch up” your recorded automation, is described in the Pro Tools Reference Guide.

7 Set the “SlpRt” track back to Auto Read, click Play in the Transport, and listen to the

results. You should hear the chorus playing back without the delay on the vocals. Click Stop when you are done listening.

8 Set the Automation Mode for the Big Mute group to Auto Write by clicking the

Automation Mode button on any of the tracks in the group (for example, cleangtr) and selecting Auto Write from the pop-up. Note how all of the tracks in the group go into Auto Write mode.

9 Play the session, and click the Mute button on any of the Auto Write enabled tracks in

the Big Mute group (for example, “clngtr”) to start writing mute automation to all tracks in the group. Try to click the Mute button at the beginning of measure 109 (she says when she [mute] comes around) for greater impact.

Digi 001 Quick Start Guide58

10 Click the Mute button on the same track again to stop writing mute automation. Try to

click the button around the beginning of measure 113 (but when she [un-mute] comes around).

MIDI

This optional section is for MIDI users. In this section, you’ll connect your MIDI device to the Digi 001 I/O Box, then we’ll try to coax some meaningful sounds out of the MIDI tracks in the Demo Session.

MIDI conﬁguration takes place in OMS (Open Music System) on the Macintosh, and in Windows Multimedia setup.

Macintosh

When you installed Digi 001, a Digi 001 driver was placed in your OMS folder. To use this driver, you need to connect your device, then configure your OMS Studio Setup. See “Installing and Configuring OMS” on page 9 for more information.

Windows

When you installed Digi 001, a Digi 001 MIDI driver was installed. To use this driver, you need to connect your device, then configure your Windows Multimedia Setup. See “Installing the Windows 98 Wave Drivers” on page 19 for more information.

MIDI Offset

When you monitor a MIDI device through the Digi 001 audio inputs by record enabling tracks, you will hear an audio delay equivalent to the number of samples speciﬁed in your Hardware Buffer settings (see “Monitoring Latency and Recording” on page 69). This audio delay is called latency. You can counteract this latency by triggering your MIDI data early, using a feature called MIDI Offset. Refer to the Pro Tools Reference Guide for more details.

Connecting and Conﬁguring a MIDI Device

To connect a MIDI device:

1 Using standard 5-pin MIDI cables, connect the MIDI In port on the Digi 001 I/O Box to

the MIDI Out connector on your device, and connect the MIDI Out port on the Digi 001 I/O Box to the MIDI In port on your device.

2 Connect the audio output or outputs of your device.

Digi 001 Quick Start Guide60

• You can connect the audio output of the device to Digi 001 by connecting analog outputs to the analog inputs on the back of Digi 001 I/O Box, or you can connect a digital device to the proper digital inputs on either the Digi 001 I/O Box or the Digi 001 PCI Card. If you are monitoring your device through the audio inputs on Digi 001, you will have to route each input to a track and record enable that track to hear output (for instructions, see Chapter 6: Recording).

• You can also monitor your device with a separate mixer that accepts analog or digital input, then route the output into the Digi 001 audio inputs when you are ready to record the audio. Read your mixer’s documentation for more information.

Using a MIDI Device with the Demo Session

To get an idea of how to assign a MIDI instrument to a track in Pro Tools LE, let’s assign an instrument to a MIDI track that’s already in the Demo session. We’ll ﬁnd and show the track “Virusplayed,” then assign a MIDI device to it. Then we’ll play back, and you can ﬁnd suitable programs on your synth or other device to reproduce the MIDI track.

To assign a MIDI device to play back the track “Virusplayed”:

1 Click the Memory Location “Tutorial Start” to go to the beginning of the tutorial. 2 Use the menu at the top of the Show/Hide Tracks List to Hide All Tracks. Then select only

“Virusplayed” to be displayed, by clicking the track name.

This section explains how to record audio and MIDI tracks using Pro Tools LE.

Routing Audio to a Track

To route audio to a track:

1 Connect your audio sources. See “Connecting Audio Sources to Digi 001” on page 32 for

more information.

2 Create the tracks you want to record on by choosing File > New Track. 3 In the Edit or Mix window, ﬁnd the I/O panel. You can show this panel if it is not visible

by selecting Display > Edit Window Shows > I/O for the Edit Window, or Display > Mix Window Shows > I/O for the Mix Window.

4 Click the Input button. 5 From the pop-up menu, select the input you are using. For example, specify Mic/Line 1

if your audio source is plugged into analog input 1, or specify Optical 7 if you are using optical input 7.

Setting Digi 001 Input Levels

Digi 001 input levels for analog inputs 1 and 2 are adjusted using the gain knobs on the Digi 001 I/O Box for each channel. Input levels for analog inputs 3–8 are softwareadjustable to accommodate a variety of equipment output levels.

The key to setting input levels is to get a signal as “loud” as possible without creating digital clipping. Signals that get close to the top of the meter in Pro Tools LE use more of the full bit range (the 16 or 24 bits that make up each audio sample). The more you maximize this bit range, the better your sound quality. And, by keeping your levels healthy, you'll get the least possible noise and best distortion performance.

But watch out for digital clipping. Clipping occurs when you feed a signal to an audio device that is louder than the circuitry can accept. The result is distortion. Digital clipping is harsh, and usually not something you want to hear at all, so watch those meters!

✽ For best signal-to-noise performance, set the Digi 001 input gain to +4 dBu

when recording devices that provide this output level.

To adjust gain on the Digi 001 (Mic/Line inputs 1–2):

1 Connect the instrument or microphone to the input. 2 If the microphone requires phantom power, apply phantom power now by pressing the

48V switch.

3 Create an Auxiliary Input track by choosing File > New Track. 4 Set the track input to the correct Digi 001 input channel (Mic/Line 1 or 2). 5 Play the instrument or sound source at the volume you will record. 6 Adjust the input gain for the channel using the gain knob on the front of the Digi 001

I/O Box. Increase or decrease gain until you are able to achieve maximum signal level without clipping. Typically such levels are in the yellow area of the track’s meter.

increasing gain

Digi 001 Quick Start Guide64

To adjust input gain on the Digi 001 (Analog inputs 3–8):

1 Connect the instrument or device to the Digi 001 I/O Box. 2 In Pro Tools LE, choose Setups > Hardware. 3 Click Other Options. 4 Set the input trim slider to match the output level of the connected instrument. Refer to

the manufacturer’s documentation for details. If you do not know the output level of the device, use the default input trim level, then ﬁne tune the input level gain using the procedure below.

5 Click Done.

✽ Increasing gain raises the noise ﬂoor. Make sure that the device you have con-

nected is outputting as strong a signal as possible without distortion, then set the input gain accordingly.

To ﬁne tune the input level gain (Analog inputs 3–8):

1 Create an Auxiliary Input track by choosing File > New Track. This can be either mono

or stereo depending on the device you are monitoring. Option-click (Macintosh) or AltClick (Windows) the fader on the track to set it to unity gain (0 dB).

2 Set the track input to the correct Digi 001 input channels or channels. 3 Play the instrument at the volume you will record. 4 Note where the instrument output signal registers on the on-screen meters in

Pro Tools LE. Good levels are in the yellow range of the Pro Tools LE track meters. If the levels hit the red, they are clipping, and you should lower the input gain.

5 If the meters are not clipping, and they are not in the yellow range, open the Other

Options dialog and increase the input gain by raising the volume slider for the appropriate input. Click Done and play the audio source again. Repeat until you have a strong signal without clipping.

Monitoring Latency and Recording

Because Pro Tools LE uses the host processor in your computer for audio processing, playback, and recording, there is a small amount of audio delay, or latency, when monitoring audio through the system. You can set the latency shorter when you are recording and monitoring through Digi 001, and longer when you are trying to achieve higher track counts with more plug-ins.

How Hardware Buffer settings affect latency

Latency (ms) Use this setting for:

cal instruments

slower attacks (bass, guitar, etc.)

cal instruments

slower attacks (bass, guitar, etc.)

Set latency in the Hardware Setup dialog box. Latency is controlled by the Hardware Buffer Size setting, and is displayed in samples. The recommended setting for listening back to audio is 512–1024 samples. For recording, when monitoring through Digi 001, the recommended setting is 128–256 samples.

▲ If have a SampleCell II Plus card, a buffer size of 128 should not be used when

running the SampleCell Editor at the same time as Pro Tools LE. Use a larger buffer setting to avoid performance errors.

Chapter 6: Recording 69

To set the Hardware Buffer Size for record or playback:

1 Choose Setups > Hardware. 2 Choose the number of samples from the H/W Buffer Size pop-up.

Low Latency Monitoring

Pro Tools LE includes a feature called Low Latency Monitoring for Digi 001 systems. This feature allows you to use a built-in mixer on the Digi 001 PCI card to record and monitor up to 16 inputs (8 analog and 8 ADAT) with extremely low latency. This mode can be very desirable for recording multiple instruments at the same time, or a band.

To enable Low Latency Monitoring:

■ Select Operations > Low Latency Monitoring.

To use Low Latency Monitoring tracks must be record-enabled, assigned to an actual audio input (not a bus), and assigned to outputs 1 or 2.

When Low Latency Monitoring is enabled, any plug-ins and sends assigned to recordenabled tracks (routed to Outputs 1–2) are automatically bypassed, and must remain bypassed. Also, these tracks will not register on meters for Master Faders.

Recording MIDI

To conﬁgure a new MIDI track for recording:

1 Create a new MIDI track. 2 In the Mix window, click on the track’s MIDI Device/Channel Selector and assign a

device and channel from the pop-up menu.

MIDI Device/Channel Selector

3 If you want, you can assign a default program change to the track. In the Mix window,

click on the Program button (Prog) and make the necessary selections for program and bank select, then click Done. Default program changes are sent when playing a track.

4 In the Mix Window, click the MIDI track’s Record button to record enable the track.

To record into the new MIDI track:

1 Put Pro Tools LE in Record mode. 2 Enable and conﬁgure the click, and set a default tempo and meter for the session. 3 Enable Wait for Note or Countoff In the Transport window. 4 Make sure MIDI > MIDI Thru is selected, then play some notes on your MIDI controller.

The MIDI instrument assigned to the track should sound, and the track’s meters should register MIDI activity.

5 In the Transport window, click Return to Zero so the start and end times are cleared. This

ensures that you’ll start recording from the beginning of the track.

6 Click Record in the Transport window.

• If using Wait for Note, the Play, Record, and Wait for Note buttons ﬂash. Recording begins when the ﬁrst MIDI event is received.

• If using Countoff, click Play. The Record and Play buttons ﬂash during the Countoff— after which, recording begins.

7 When you have ﬁnished recording, click Stop in the Transport window. The newly

recorded MIDI data appears as a MIDI region in the Edit window, and in the MIDI Regions List.

Chapter 6: Recording 71

To play back the recorded MIDI track:

1 Click the Record button for the MIDI track to take it out of record-ready mode. 2 In the Transport window, click Return to Zero. 3 Click Play in the Transport window to begin playback. The recorded MIDI data plays back

through the track’s assigned instrument and channel.

Recording with a Footswitch

You can use a standard footswitch (for example, a synth sustain pedal) with QuickPunch to “punch in” when recording audio. You can also punch in when recording MIDI, without enabling QuickPunch. For details on Punch recording, see the Pro Tools Reference Guide.

Pro Tools LE only detects the footswitch if you connect it to the Digi 001 I/O Box before you launch Pro Tools LE.

To connect a footswitch to Digi 001:

■ Plug a footswitch into the Footswitch connector on the back of the Digi 001 I/O Box.

connect footswitch here

To punch in when recording audio with QuickPunch:

1 Enable QuickPunch (Operations > QuickPunch). 2 Set input routing and click the Record button on each audio track you want to punch in.

You can punch in on up to 8 audio tracks while playing 24 tracks, or you can punch in on up to 16 tracks while playing 16 tracks.

3 Click Play in the Transport window. Press the footswitch to begin recording (punch in)

on all record-enabled tracks. Press the footswitch again to stop recording (punch out).

Note that the session continues to play, and you can continue to punch in and out as many times as you want with the footswitch.

To punch in when recording MIDI:

1 Set your MIDI input routing and click the Record button on each MIDI track you want

to punch in. QuickPunch is not required to punch in on MIDI tracks.

2 Click Play in the Transport window. Press the footswitch to begin recording (punch in)

on all record-enabled tracks. Press the footswitch again to stop recording (punch out).

Digi 001 Quick Start Guide72

Recording with an ADAT

You can use Digi 001 to interface with an ADAT, either to record tracks from an ADAT into Pro Tools LE for editing, or to record tracks from Pro Tools LE to an ADAT.

Using Output Pairs

Because of the way that outputs function in Pro Tools LE, each track “looks for” a stereo output pair. This means that in order to record to eight ADAT tracks, you have to send 4 pairs of Pro Tools LE tracks (each pair panned hard left and right) to Digi 001’s 4 pairs of ADAT Optical Digital outputs.

To record ADAT tracks into Pro Tools LE:

1 Connect the Optical Out connector from your ADAT deck to the Optical In connector on

the back of the Digi 001 PCI Card.

2 Open or create a session in Pro Tools LE. 3 Record enable up to 8 audio tracks (depending on how many tracks are used on the ADAT

tape).

4 Route ADAT Optical Inputs 1–8 to your eight tracks. 5 Click Record in the Transport window. 6 Click Play in the Transport window to begin recording, then press Play on the ADAT. 7 When playback from the ADAT tape is ﬁnished, click Stop in the Transport window, or

press the Spacebar.

Chapter 6: Recording 73

To record Pro Tools LE tracks to an ADAT:

2 Open the session you want to record to the ADAT. 3 Record enable up to 8 audio tracks on the ADAT. 4 Pan 4 pairs of tracks so that each pair is panned hard stereo (one track of each pair is

panned all the way left, and the other is panned all the way right).

5 Route each track pair to a separate Optical output pair by selecting from the Output pop-

up menu for each track. For example, if one of your pairs was 3(L)–4(R), you could route this pair to the output labeled #1/9 Optical 1-#1/10 Optical 2.

6 Start recording on the ADAT, then click Play in the Transport window in Pro Tools LE.

When playback is complete, stop both systems.
