    							CUBASE LE22 – 442 Working with System Exclusive messages
    Introduction
    System Exclusive (Sys Ex) is a special type of MIDI message used to 
    send data that only make sense to a unit of a certain make and type. 
    Every major MIDI manufacturer has its own Sys Ex identity code. Sys-
    tem Exclusive messages are typically used for transmitting patch data, 
    i.e. the numbers that make up the settings of one or more sounds in a 
    MIDI instrument.
    Cubase LE allows you to record and manipulate System Exclusive data 
    in various ways. This chapter points to various features that help you 
    manage and create System Exclusive data.
    Bulk dumps
    Recording a bulk dump in Cubase LE
    In any programmable device, all settings are stored as numbers in 
    computer memory. Change those numbers, and you will change the 
    settings.
    Normally, MIDI devices allow you to dump (transmit) all or some set-
    tings in the devices memory, in the form of MIDI System Exclusive 
    messages. Return these messages, and you get the settings back. 
    This is (among other things) a way of making backup copies of the 
    settings of any instrument.
    If your instrument allows the dumping of a few or all of its settings via 
    MIDI by activating some function on the front panel, this dump will 
    most probably be recordable in Cubase LE.
    1.Open the Preferences dialog from the File menu (on the Mac, this is 
    located on the Cubase LE menu) and select the MIDI–Filter page.
    As described on page 42, this allows you to govern which MIDI event types should be 
    recorded and/or thru-put.

    2.Deactivate the Sysex checkbox in the Record section, but make sure 
    the Sysex checkbox in the Thru section is activated.
    With this setting (shown in the figure above), SysEx messages will be recorded but not 
    echoed back out to the instrument (which could lead to strange results).
    3.Activate recording on a MIDI track and initiate the dump from the front 
    panel of the instrument. 
    4.When done recording, select the new part and open the List Editor 
    from the MIDI menu.
    This allows you to check that the System Exclusive dump was recorded – there should 
    be one or several SysEx events in the part/event list.
    ❐If your MIDI instrument doesn’t offer a way to initiate a dump “by itself”, 
    you have to send a Dump Request message from Cubase LE to start the 
    dump. You will then have to use the SysEx Editor (see page 446) to insert 
    the specific Request message (see the instrument’s documentation) at 
    the beginning of a MIDI track. When you activate recording, the Request 
    message will be played back (sent to the instrument), the dump will start 
    and be recorded as described above.

    Transmitting a bulk dump back to a device
    1.Make sure the MIDI track with the System Exclusive data is routed to 
    the device.
    You may want to check your device’s documentation to find details about which MIDI 
    channel should be used, etc.
    2.Solo the track.
    This might not be necessary, but it is a good safety measure.
    3.Make sure the device is set up to receive System Exclusive data (of-
    ten, the reception of SysEx is turned off by default).
    4.If necessary, put the device in “Standby to Receive System Exclusive” 
    mode.
    5.Play back the data.
    Some advice
    • Dont transmit more data than you need. If all you want is a single program, 
    dont send them all, it will only make it harder to find the one you want. Usually, 
    you can specify exactly what you want to send.
    • If you want the sequencer to dump the pertinent sounds to your instrument 
    each time you load a song, put the SysEx data in a silent “count-in” before the 
    song itself starts. 
    • If the dump is very short (for instance, a single sound) you can put it in the 
    middle of the Song to re-program a device on the fly. However, if you can 
    achieve the same effect by using Program Change, this is definitely prefera-
    ble, since less MIDI data is sent and recorded. Some devices may be set up to 
    dump the settings for a sound as soon as you select it on the front panel.
    • If you create parts with useful “SysEx dumps”, you can put these on a special 
    muted track. When you want to use one of them, drag it to an empty unmuted 
    track and play it back from there.
    • Do not transmit several SysEx dumps to several instruments at the same time.
    • Make a note of the current Device ID setting of the instrument. If you change 
    this, the instrument may refuse to load the dump later.

    Recording System Exclusive parameter changes
    Often you can use System Exclusive to change individual settings in a 
    device, open up a filter, select a waveform, change the decay of the 
    reverb etc. Many devices are also capable of transmitting changes 
    made on the front panel as System Exclusive messages. These can be 
    recorded into Cubase LE, and thus incorporated into a regular MIDI 
    recording.
    Heres how it works: lets say you open up a filter while playing some 
    notes. In that case, you will record both the notes and the System Ex-
    clusive messages generated by your opening of the filter. When you 
    play it back, the sound changes exactly like it did when you recorded it.
    1.Open the Preferences dialog from the File menu (on the Mac, this is lo-
    cated on the Cubase LE menu), select the MIDI–Filter page and make 
    sure that System Exclusive gets recorded.
    2.Make sure the instrument is actually set to transmit front panel control 
    movements as System Exclusive data.
    3.Record normally.
    When you’re done, you can check that the events were recorded properly in the List 
    Editor.

    Editing System Exclusive messages
    While System Exclusive events are shown in the List Editor, their entire 
    content is not (only the beginning of the message is displayed in the 
    Comment column for the event). Furthermore, you cannot edit the 
    event (other than moving it) as you can with other event types in the 
    List Editor.
    Instead, you use the MIDI SysEx Editor for this.
    •To open the SysEx editor for an event, click in the Comments column 
    for the event in the List Editor.
    The display shows the entire message on one or several lines. All Sys-
    tem Exclusive messages always begin with F0 and end with F7 with a 
    number of arbitrary bytes in between. If the message contains more 
    bytes than fit on one line, it continues on the next. The Address indica-
    tion to the left helps you find out on which position in the message a 
    certain value resides.

    Selecting and viewing values
    To select a value, either click on it or use the cursor keys. The se-
    lected byte is indicated in various formats:
    • In the main display, values are shown in Hexadecimal.
    • To the right of this, values are shown as ASCII.
    • At the bottom of the dialog, the selected value is shown in binary and decimal 
    formats.
    Editing a value
    The selected value can be edited directly in the main display or in the 
    decimal and binary displays. Just click on it and type in the desired 
    value as usual.
    Adding and deleting bytes
    Using the Insert and Delete buttons, or their corresponding computer 
    keyboard keys, you can add and delete bytes from the message. In-
    serted data will appear before the selection.
    Importing and exporting Data
    The Import and Export buttons allow you to get SysEx data from disk 
    and to export the edited data into a file. The file format used is called 
    “Raw SysEx” (.SYX), which means that data is saved exactly as is, in a 
    binary file. Only the first dump in a “SYX” file will be loaded.
    This format should not be confused with MIDI Files.

    Export Audio Mixdown 
    						
    							CUBASE LE23 – 450 Export Audio Mixdown
    Background
    The Export Audio Mixdown function allows you to mix down all audio 
    tracks, complete with effects and automation, into one or several audio 
    files, in one of several file formats. The following rules apply:
    • All audio you hear on playback will be included in the mixdown file!
    You can however choose whether you want effects and automation included in the 
    mixdown, as described below.
    • Cubase LE can export to a number of different file formats, each with different 
    options.
    See page 453.
    • MIDI tracks are not included in the mixdown! 
    To make a complete mixdown containing both MIDI and audio, you first need to record 
    all your MIDI music to audio tracks (by connecting the outputs of your MIDI instruments 
    to your audio inputs and recording, as with any other sound source).
