INSTALLATION PROCESS

    If you do not have a previous copy of the drivers installed, and 
    you are installing this Sound Card plus Driver package for the
    first time, you may proceed to the FIRST TIME INSTALLATION section. 
    However, if you are updating your previous installed drivers, you 
    MUST follow the UPDATE PREVIOUS DRIVERS section below in order to 
    succesfully install the new drivers.

    UPDATING PREVIOUS DRIVERS

    [Updating "TerraTec MAESTRO 16/96" Driver]

    1. You should have the latest drivers on a floppy diskette ready
       for installation.

    2. Start Windows 95 and proceed to the Control Panel folder and 
       select (double click) the Add New Hardware icon. This will 
       add/update the MAESTRO 16/96 and it's associated drivers.

    3. When prompted by Windows 95 for the Auto-Scan option for 
       detecting new devices on your System - select NO and proceed
       to the next page.

    4. Windows 95 will display a list of known devices that you 
       currently wish to install. Select "Other Devices" eventhough
       the name of the device is included in the list. This forces
       Windows 95 to perform a fresh install for your device. Select
       Next to proceed.

    5. Windows 95 will again display a list containing manufacturer 
       names and at which point you should ignore the list and select
       the "Have Disk..." button. This tells Windows 95 to read
       special installation instructions from your diskette to 
       correctly install the drivers for your MAESTRO 16/96.
       You will have to direct Windows 95 to the proper location of 
       the floppy diskette.

    6. Once information from the floppy diskette has been read by
       Windows 95, a list of devices available for installation will
       be displayed. This list contains driver setup options pertaining
       to your Sound Card's capabilities. For example, if your Sound
       Card has an IDE CD-ROM interface which you wish to connect your
       IDE CD-ROM to, select the appropriate option to enable this
       setup. If your Sound Card does not contain any options other
       than Audio functions, then just select the first option.

    7. Windows 95 will now proceed to install the drivers needed for 
       your device and configure your device accordingly. Once your 
       device has been successfully configured, Windows 95 will prompt 
       you to restart your system - select Yes for the new drivers to 
       take effect. YOU MUST REBOOT for the changes to take effect!

    8. Install REAL MODE DOS Support: During the system reboot process
       the DOS Installer will be invoked automatically. Please follow 
       the instruction of DOS Installer and it will setup the  sound 
       card properly for the Real Mode DOS games or applications.


    FIRST TIME INSTALLATION
    
    Install the Sound Card into your system and reboot your machine; 
    Windows 95 should detect new PnP resource on your Sound Card and
    prompt you for the installation files. At this point, insert the
    MAESTRO 16/96 Windows 95 Driver diskette into your floppy drive and
    let Windows 95's Device Manager direct you through the installation
    of the drivers.

    When Device Manager finds a new device but cannot determine/find the
    correct driver for the device, it will prompt you for the location 
    of the drivers associated with the device and will expect that the
    drivers are from a floppy diskette. At this time, select OK if the 
    option "Drivers from disk..." is enabled and Device Manager will 
    proceed to copy the drivers from the diskette. However, if the option 
    "Windows Compatible Driver" is enabled, select OK as well to direct 
    Device Manager to make use of default drivers for that particular 
    device.



RECONFIGURATION OF RESOURCES

    The SoundSystem MAESTRO 16/96 is a fully Plug-n-Play device and all it's
    resources should be reconfigurable on-the-fly unless due to a
    similar conflicting device present in the system.

    To reconfigure the resources, use the SYSTEM icon located in your
    Control Panel folder and choose Device Manager. From Device Manager,
    double click the "SoundSystem TerraTec MAESTRO 16/96" option and the
    list of installed MAESTRO Audio devices will be displayed. Double click
    on the device which you wish to change resources for. Once resources
    have been changed, the driver will be automatically reconfigured to 
    operate with the new resources and function as before.



AUDIO SUPPORT under REAL MODE DOS

    [Systems with Win95/DOS Setup]
    To enable support for DOS Games or multimedia applications under
    a REAL MODE DOS environment, please follow the Step 8 of INSTALL
    PROCESS. If you decide not to do DOS setup now, it's OK to skip it.
    Type C:\SND4DOS at real mode DOS prompt at any time will bring up
    the DOS Installer.

    [Systems with Dual Boot Win95/Win31 Setup]
    Please run TerraTec's Win31/DOS Install package at Real Mode DOS
    prompt. When prompted during the installation for the path to 
    your Windows directory, specify the path if you have Windows 
    3.1 installed on your system (under a seperate directory from 
    Windows 95). Select None if you do not have Windows 3.1 installed.




AUDIO SUPPORT under WINDOWS 95 DOS BOX

    DOS Game support has been added for this release and is fully 
    functional. During the setup for your DOS games, you must ensure that
    the current resources assigned to the sound card matches with the
    current settings requested by your DOS game. To find out what resources
    are currently assigned to the sound card, proceed to open the properties
    box associated with the "SoundSystem TerraTec MAESTRO 16/96" (Device Manager)
    and select the Resource tab. From the Resources box, you should see the
    current I/O Address range for Input/Output Range Number 1. We recommend 
    the 220 Hex address range as opposed to the 240 Hex be selected as most 
    games support 220 Hex by default. We also recommend the Interrupt and 
    Direct Memory Access settings of 7 and 1 respectively. Reconfigure these 
    resources as appropriate and select OK for Device Manager to dynamically 
    change and update your current resources and configure the hardware. 
    At this point, you may setup your DOS game with the settings which you 
    have just configured.

    Also, if you have a Wave Table Device on board or attached to your
    sound card, you should also follow the recommended steps above but
    this time check on the "TerraTec MAESTRO 16/96 MPU-401" device settings
    instead. You will need it's current settings if you wish to enable
    General MIDI support in your DOS games.

    To ensure an ideal environment for DOS games, it is recommended that
    you modify the Idle Sensitivity property of your DOS Game environment
    to High. To do this, press the ALT+ENTER keys to change to a DOS Box
    Window (if not already in a Windowed session) and click on the top left
    hand corner of the DOS Box Window. A drop down menu will appear and
    at which point you should select Properties. Select the Misc tab and
    proceed to modify the above mentioned property.



HOT-KEY SUPPORT under WINDOWS 95 DOS BOX

    The following are the Hot-Keys and their associated channel controls.

    <CNTRL>+<ALT>+M     = Decrease Master Volume
    <SHIFT>+<ALT>+M     = Increase Master Volume
    <CNTRL>+<SHIFT>+M   = Mute Master Volume

    <CNTRL>+<ALT>+V     = Decrease Voice (Digital Sound) Volume
    <SHIFT>+<ALT>+V     = Increase Voice (Digital Sound) Volume
    <CNTRL>+<SHIFT>+V   = Mute Voice (Digital Sound) Volume

    <CNTRL>+<ALT>+F     = Decrease FM Music Volume
    <SHIFT>+<ALT>+F     = Increase FM Music Volume
    <CNTRL>+<SHIFT>+F   = Mute FM Music Volume



FULL-DUPLEX DUAL-DMA SUPPORT

    To enable Dual-DMA channel operation for simultaneous playback and
    recording, please ensure the following:
   
    1. The DMA resource settings under Device Manager must be different
       and paired as follows: 
                              
               Playback DMA:   0    1    3
               Recording DMA:  1    0    0

    2. The frequency format (eg. 11KHz, 22KHz..) must be the same during
       simultaneous playback and recording.
