Tips and Hints
--------------
   1) Battlezone: If you are using the game Battlezone from Activision,
      it is recommended that you leave the number of Sound Channels
      set to the game default value of 5. If you experience any
      slight distortion while playing the game, try decreasing the
      Monster Sound Acceleration Level by one or two notches. The
      Acceleration Level control is located on the Preferences page of
      the Monster Sound taskbar utility.

   2) Incoming: If you are using the game Incoming from Rage, and you
      have the Midisoft Internet Sound Bar application running on the
      desk top, you may experience the error "CD Not Present". Try 
      closing the Internet Sound Bar application prior to launching 
      Incoming.

   3) Unreal: If you are using Unreal from GT Interactive, you should 
      disable the A3D Splash option located on the 3D Audio page of the
      Monster Sound taskbar applet. The A3D Splash can interfere with
      the full screen operation of the game.

   4) Quake II from Id Software (and other applications which call
      certain sequences of DirectSound buffer intialization and
      subsequent format changes): Minor popping will be exhibited during
      application startup on Windows 98 systems, which is not heard
      under Windows 95.  This is due to changes in Win98's DirectSound
      implementation.  It is not related to the Monster Sound's hardware
      /software and will not affect actual gameplay. This problem will
      be addressed in a future release of Windows 98 and/or DirectX.


Limitations
-----------
   1) The Sound Blaster Emulation feature does not support FM or 
      Gameport emulation. It is recommended that you keep your existing
      legacy audio card installed in your system for the best DOS
      application support.
