    VST Instruments and Instrument tracks
    VST plug-ins (with higher delay than the threshold 
    value) which are activated for VST Instrument channels, 
    audio track channels that are record enabled, group chan-
    nels and output channels will be turned off when you acti-
    vate Constrain Delay Compensation.
    VST plug-ins activated for FX channels are not turned 
    off but their delay is disregarded by the program (delay 
    compensation is turned off).
    After recording or using a VST Instrument with Constrain 
    Delay Compensation, you should turn off the function to 
    restore full delay compensation.
    External instruments
    An external instrument bus is an input (return) to your au-
    dio hardware, along with a MIDI connection via Nuendo 
    and few additional settings. External instrument busses 
    are created in the VST Connections window. All external 
    instrument busses you have created will appear on the 
    VST Instrument pop-up menus and can be selected in the 
    same way as any VST Instrument plug-in. If you select an 
    external instrument, you play it via MIDI as usual (you have 
    to create a MIDI device to play it) and the sound (synth au-
    dio output) will come in to the VST environment where you 
    can apply processing etc. For more information on exter-
    nal instruments, see “Setting up external instruments” on 
    page 19.

    Surround sound
    Background
    What is Surround sound?
    Surround is a common name for various techniques for 
    positioning audio in reference to the listener. Whereas 
    regular stereo is limited to left/right positioning, within a 
    relatively narrow field, surround sound opens possibilities 
    of positioning an audio source anywhere around the lis-
    tener.
    Surround sound comes in many flavors, from the ill-fated 
    Quadraphonic format for vinyl discs launched in the 70s, 
    to today’s more successful incarnations.
    The differences between the formats are in two areas:
    The number and configuration of speakers.
    This varies from two speakers up to 12.
    The intended final coding format.
    This depends on the media the audio will be “stored” on: film, broadcast 
    video or DVD, for example.
    Surround sound is a large topic, there are entire books 
    and regular publications devoted to the subject. This 
    chapter will not provide an in-depth introduction to sur-
    round sound as such. Instead it will concentrate on the 
    specific implementation in Nuendo.
    Surround sound in Nuendo
    Nuendo has integrated surround sound features with sup-
    port for several formats. This support goes all the way 
    through the audio path – all audio channels and busses 
    can handle multiple speaker channel configurations (up to 
    12 channels). A channel in the mixer can either carry com-
    plete surround mixes, or an individual speaker channel 
    which is part of a surround setup.
     Audio channels can be routed freely to surround channels.
     The Surround Panner function in the mixer allows you to 
    graphically position channels in the surround field.
     The Mixconvert plug-in allows conversion of one surround 
    channel into another with a different speaker configuration. 
    Nuendo places Mixconvert automatically where needed. Nuendo is ready for surround specific plug-ins, that is plug-ins 
    with multi-channel support specifically designed for surround 
    sound mixing tasks (the included “Mix8to2” plug-in is an ex-
    ample of this). There are also surround aware plug-ins, which 
    are not designed specifically for Surround but which due to 
    their multi-channel support work well in a Surround configura-
    tion. An example is the Surrounddither plug-in.
     You configure Nuendo for surround by defining input and out-
    put busses in the desired surround format, and specifying 
    which audio inputs and outputs should be used for the differ-
    ent channels in the busses. This is done in the VST Connec-
    tions window.
    Requirements for using Surround
    The following additional equipment is required for taking 
    advantage of the surround sound implementation in Nu-
    endo:
    An audio card with more than two outputs.
    The card must have as many outputs as the surround format you plan to 
    select.
    A matching amplifier/speaker configuration.
    Encoding
    The result of a surround mix in Nuendo is either the multi-
    channel audio sent from the surround output bus to your 
    surround speaker setup, or (if you use the Export audio 
    feature) audio file(s) on your hard disk. Exported surround 
    mixes can either be split (one mono file per speaker chan-
    nel) or interleaved (a single file containing all the surround 
    channels).
    Getting from this step to the final product (surround sound 
    on DVD disc, DTS, etc.) requires special software and 
    possibly hardware. This equipment will encode the signal 
    into the desired format, possibly compress the audio and 
    store it on the final media.
    Exactly what type of software and/or hardware you need 
    depends on what kind of format you are mixing for and is 
    not dependent on Nuendo in any way.
    Steinberg provides Dolby Digital and DTS encoders for 
    purchase, tailored for use with Nuendo.

    About surround plug-ins
    Included with the program are some specific surround-
    plug-ins. These are:
    MatrixEncoder and MatrixDecoder.
    These are used for working with LRCS Surround encoded material. In 
    LRCS Surround, four audio channels are converted to two channels, for 
    distribution via regular video and broadcast formats. These plug-ins per-
    form such conversions (in both ways) and are compatible with the LRCS 
    Surround format.
    Mixconvert
    Mixconvert gives you an easy way to take surround mixes and convert 
    them to other formats with less channels. For example, Mixconvert can 
    be used to downmix a 5.1 surround mix to a normal stereo mix. This plug-
    in is unique in that Nuendo will automatically insert it in place of the chan-
    nel panner or aux send panner in certain situations. Please refer to the 
    manual “Nuendo Expansion Kit – Cubase Music Tools for Nuendo 4” for 
    complete information about Mixconvert.
    Mix6to2
    The Mix6to2 effect allows you to control the levels of up to six surround 
    channels, and to mix these down to a stereo output. 
    Mix8to2
    The Mix6to2 effect allows you to control the levels of up to eight sur-
    round channels, and to mix these down to a stereo output.
    Mixer Delay
    The Mixer Delay effect is useful for time aligning surround speakers if 
    your room configuration does not allow for proper ITU-R speaker place-
    ment. It is also handy for re-routing surround channels to their proper 
    speaker channels in your setup (refer to the separate manual “Nuendo 
    Expansion Kit – Cubase Music Tools for Nuendo 4” for more information 
    about Mixer Delay.
    SurroundDither
    This is a dithering plug-in capable of handling six channels at the same 
    time – use this for applying dithering to a surround output bus.
    SurroundPanner
    This is described in the section “Using the Surround Panner” on page 
    208.
    ÖSurround plug-ins (apart from the SurroundPanner) 
    are described in the separate manual “Nuendo Expansion 
    Kit – Cubase Music Tools for Nuendo 4”.
    The VST Connections window
    In this window you can add input and output busses. 
    There is a complete selection of common surround con-
    figurations available, as well as standard mono or stereo 
    busses.
    The Bus Name column contains the currently configured 
    busses as they will appear in the input and output routing 
    pop-ups in the mixer.

    folded, displaying the individual speaker channels, with their physical 
    output ports displayed in the Device Port column to the right.

    Surround sound
    Surround in the mixer
    Surround sound is supported throughout every stage of 
    the signal path in the Nuendo mixer, from input to output 
    bus. Each bus or audio channel can carry up to 12 sur-
    round speaker channels.
    In the output channel section of the mixer you can control 
    the master levels for configured busses. The level meter 
    for a bus (or channel in the mixer) that carries multiple sur-
    round channels will show multiple level bars, one for each 
    speaker channel in the surround configuration.
    Operations
    Setting up the surround configuration
    Output bus configuration
    Before you can start working with surround sound, you 
    have to configure a surround output bus, through which all 
    the speaker channels of the chosen surround format are 
    routed. How to add and set up busses is described in de-
    tail in the section “Setting up busses” on page 11. Here is 
    a brief run through:
    1.Open the VST Connections window from the Devices 
    menu.
    2.Click the “Outputs” tab.
    3.Click the “Add Bus” button and select one of the pre-
    set formats from the Configuration pop-up (see below).
    The new bus appears with the ports visible.
    4.By clicking in the Device Port column you can now 
    route the speaker channels to the desired outputs of your 
    audio hardware.
    5.If you like, rename the output bus by clicking its name 
    and typing in a new one.
    This name will appear in the mixer and on routing pop-ups.
    The following surround configurations are included:
    Here, the SurroundPanner is used for positioning 
    the sound “dynamically” in the surround field.
    Using the Output Routing pop-up, 
    audio channels can be routed di-
    rectly to surround channels.
    Format Description
    LRCS
    LRCS refers to Left Right Center Surround, where the 
    surround speaker is center-rear positioned. This is the 
    original surround format that first appeared as Dolby Ste-
    reo in cinema and later as the home cinema format Dolby 
    ProLogic.
    5.0
    This is the same as 5.1 (see below) but without the LFE 
    channel. The LFE channel is optional in 5.1 and if you 
    don’t plan to use it, you might find this option more con-
    venient.
    5.1
    This format is one of the most popular in cinema and 
    DVD. In its various cinema and DVD encoding implemen-
    tations (established by different manufacturers) it is re-
    ferred to as Dolby Digital, AC-3, DTS and MPEG 2 
    Multichannel. 5.1 has one center speaker (mainly used 
    for speech), main left and right speakers, and two sur-
    round speakers (mostly for sound effects). Additionally a 
    subchannel (LFE – Low Frequency Effects) with lower 
    bandwidth is used for special low frequency effects.

    Surround sound
    Child busses
    Essentially a child bus is a bus within a (bigger) bus. Typi-
    cally you may want stereo child busses within your sur-
    round bus – this allows you to route stereo tracks directly 
    to a stereo speaker pair within the surround bus. You may 
    also want to add child busses in other surround formats 
    (with fewer channels than the “parent bus”).
    Once you have created a surround bus, you can add one or 
    several child busses to it by right-clicking the bus and se-
    lecting “Add Child Bus”. This is described in detail in the 
    section “Adding a child bus” on page 13.
    Input bus configuration
    To work with surround sound in Nuendo, it is often not 
    necessary to configure a surround format input bus. You 
    can record audio files via standard inputs, and easily route 
    the resulting audio channels to surround outputs at any 
    stage. You can also directly import multi-channel files of 
    specific surround format onto audio tracks of the same 
    format.
    You should add a surround input bus in the following cir-
    cumstances:You have existing audio material in a specific surround 
    format, and you wish to transfer this material into Nuendo 
    as a single, multi-channel file.
    You wish to record a surround setup “live”.
    In both cases, you can add and configure an input bus of 
    the format you wish to use in the VST Connections dialog 
    so that each input on your audio hardware is routed to the 
    corresponding speaker channel.
    To add an input bus, use the same general method as de-
    scribed for output busses (see “Output bus configuration” 
    on page 205), but select the “Inputs” tab instead.
    Routing channels directly to surround channels
    If you want to place an audio source in one separate 
    speaker channel only, you can route it directly to that 
    speaker channel. This is useful for pre-mixed material or 
    multi-channel recordings that don’t require panning.
    1.Open the mixer and locate the channel you wish to 
    route.
    2.From the output routing pop-up menu, select the cor-
    responding surround speaker channel.
    If a stereo audio channel is routed directly to a speaker 
    channel, the left/right channels will be mixed to mono.
    The pan control for the audio channel governs the balance between the 
    left and right channel in the resulting mono mix. Center pan will produce 
    a mix of equal proportion.
    Routing channels using child busses
    Child busses provide a way to route stereo (or multi-chan-
    nel) audio channels to specific speaker channels in a sur-
    round configuration. 
    The most obvious application of a child bus is when you 
    wish to add a stereo channel to two specific left/right sur-
    round speaker channels.
    8.0 Music
    Same as 7.0 Music but with the addition of a Center Sur-
    round channel.

    Surround sound
    If you have added a child bus within a surround bus (see 
    above), it appears as a submenu item within the surround 
    bus on the output routing pop-up menu. Select this to 
    route a stereo audio channel directly to that stereo 
    speaker pair in the surround bus.
    Using the Surround Panner
    Nuendo has a special feature for graphically positioning a 
    sound source in a surround field. This is actually a special 
    plug-in which distributes the audio from the channel in 
    various proportions to the surround channels.
    1.Open the mixer and locate the channel you wish to 
    position.
    This could be a mono or stereo channel.
    2.From the output routing pop-up menu, select the 
    “whole surround bus” option (not a specific speaker 
    channel).
    A miniature graph of the surround plug-in interface appears above the 
    fader in the channel strip.
    When the “whole surround bus” is selected, the channel strip shows a 
    miniature surround control. 
    3.You can click and drag directly in the miniature image 
    to move the sound in the surround field.
    The horizontal red strip to the right controls the subbass (LFE) level (if 
    available in the selected surround format).
    You can also view a slightly larger version of this control 
    by selecting “Panner” on the View options pop-up menu 
    for the extended mixer panel.
    This mode offers click and drag-panning as well as numerical values for 
    left/right balance, front/rear balance and LFE amount – enter the desired 
    number or use the mouse wheel to adjust them.
    The SurroundPan can also be displayed in the Inspector 
    for all audio channel track types. To display the Surround 
    Pan tab in the Inspector, make sure the corresponding op-
    tion is enabled in the Inspector context menu.
    For total control over surround panning, double-click on 
    the miniature image to open the full Surround Panner 
    interface in a separate window. 
    						
    							209
    Surround sound
    The SurroundPan controls
    The SurroundPan plug-in interface in Standard, Position and Angle 
    mode, respectively.
    The SurroundPan plug-in allows you to position your au-
    dio in the surround field. It consists of an image of the 
    speaker arrangement, as defined by the output bus se-
    lected on the output routing pop-up menu, with the sound 
    source indicated as a gray ball. 
    Mode – Standard/Position/Angle
    The Standard Mode/Position Mode/Angle Mode switch 
    allows you to work in three modes:
     In both Standard and Position mode, the speakers in the front 
    are aligned, as they would normally be in a cinema-type situa-
    tion. This means that the front speakers are at a varying dis-
    tance from the center. Standard mode (default) is the best 
    mode for moving sources between speakers without level at-
    tenuation.
     Angle Mode is the traditional surround sound mixing definition. 
    Note that here the speakers are defined as being at equal dis-
    tance from the center. This is not really a true representation of 
    for example a cinema, but has still proven to work well in many 
    situations.
    Speakers
    The speakers in the panel represent the chosen surround 
    configuration. 
    The speakers in the front are aligned, as they would nor-
    mally be in a cinema-type situation. 
    This means that the front speakers are at a varying distance from the 
    center, allowing you to move sources between speakers without level 
    attenuation.
    You can turn speakers on and off by clicking them with 
    [Alt]/[Option] pressed. When a speaker is turned off, no 
    audio will be routed to that surround channel.
    Positioning and levels
    A sound source is positioned either by clicking or by drag-
    ging the gray “ball” around in the panel (or by using key 
    commands, see below). By dragging during playback you 
    can record automation, see “Enabling and disabling the 
    writing of automation data” on page 214.
    In Standard Mode, the signal levels from the individual 
    speakers are indicated by colored lines from the speakers 
    to the center of the display.
    In Position Mode, the concentric circles will help you 
    determine the level of the signal at a certain position.
    The yellow circle represents -3dB below nominal level, the red circle is at 
    -6dB and the blue is located at -12dB. These are affected by attenua-
    tion, see below.
    !The text below assumes that the Mono/Stereo pop-
    up is set to “Mono Mix”. For more information on the 
    other modes, see below. 
    						
    							210
    Surround sound
    In Angle Mode, a red arc helps you determine the per-
    ceived “range” of a source. The sound will be at its loud-
    est in the middle of the arc and will have dropped in level 
    towards the ends.
    Exactly how levels are handled may require some explana-
    tion:
    When you move a source around, a number will indicate 
    the loudness in each speaker.
    This is a value in dB (decibel) and is relative to the nominal level of the 
    source. In other words, 0.0 (dB) represents full level.
    If you position the source far enough away from a 
    speaker, its level will drop to zero (indicated by an infinity 
    symbol).
    The signal levels from the individual speakers are indi-
    cated by colored lines from the speakers to the center of 
    the display.
    You can use modifier keys to restrict movement in vari-
    ous ways:
    In Standard and Position Mode:
    In Angle Mode:
    There is also a special set of key commands for working in 
    the SurroundPan window.
    The LFE dial (all modes)
    If the selected surround setup includes an LFE (Low Fre-
    quency Effects) channel, a separate LFE level dial will be 
    available in the SurroundPan window. Use this to set the 
    signal amount sent to the LFE channel. You can also set 
    this using the small red strip to the right of the Surround 
    Panner in the mixer channel strip, or by typing in a number 
    in the LFE value field in the larger Surround Panner that 
    can be shown in the extended channel strip.
    The Surround Panner in the channel strip (bottom) and in the extended 
    panel of the mixer channel strip (“Panner” selected on the View options 
    pop-up menu).
    Mono/Stereo pop-up (All Modes)
    If you have a mono channel the Mono/Stereo pop-up is by 
    default set to Mono Mix. The panner will then behave as 
    described above.
    If you have a stereo channel, you have the option of using 
    one of the three Mirror modes. Two gray balls will then ap-
    pear, one for each channel (L/R). This will allow you to 
    move the two channels symmetrically, by dragging one of 
    them. The three modes allow you to select which axis 
    should be used for mirroring.
     The default mode for stereo channels is the Y-Mirror mode.
     If you run a stereo signal through the panner in Mono Mix 
    mode, the two channels will be mixed together before entering 
    the plug-in.
     If you run a mono signal through the plug-in in one of the ste-
    reo modes, the signal will be split before entering the plug-in.
