  5. Attention: Windows System Sounds
 ------------------------------------------

* After the first installtion of an audio device driver,
  Windows 2000/XP switchs on the Windows System Sounds per default.
  The system will playback these sound if a message box appears or
  a windows will be minimized or maxminized.
  The use of this system sounds may cause some problems in conjuction
  with running audio applications.

* Per default the driver takes care of a synchron start and stop of all
  analog devices of the Marc 4 Midi. This is a really important feature for
  each multichannel harddiskrecording program but it may cause conflicts 
  with the windows system sounds.
  If a running playback- or recording session will be interrupted by
  a system sound (because of a message box or window actions) the
  playback- or recording session will STOP too and the related audio
  application will hang (under specially circumstances) in a undefined state .
  You can solve this behavior by switching off the system sounds
  (Control Panel->System Sounds) or by deactivating the Start/Stop
  Synchronization Option of the Marc 4 Midi driver. 
  (Taskbar->Marc 4 Midi Icon Doubleclick->Settings) .
