MIDIA(1)

NAME
midia - a software only midi file player for sgi computers

SYNOPSIS
midia [-v]

DESCRIPTION

   Midia plays midi files on Silicon Graphics machines having the libaudio hardware/software such as the Indigo or Indy machines. No other special midi hardware is neccessary. Use the -v option to show the patch files and their information headers.

GETTING STARTED

   Before running midia you will need to set the GUS_ENVIRONMENT variable to point to the directory containing the .pat instrument samples (setenv GUS_ENVIRONMENT directory). In the unlikely event the player freezes during play or while loading hit ctrl-c to bring it back. To activate help mode press the help button. In help mode any active button or item selected will now display a short help form instead of activating its normal function.

USAGE HINTS

   Some midi files don't comply with the General Midi Specification. These files require that you select the proper instrument for each track or select percussion if it is a percussion track (-1 is a percussion track in the .cfg files). If you are lucky then the instrumentation will appear in the info dialog. You can also set up a configure file to automatically map them. Look at the included .cfg files for guidance.
   If you encounter digital clipping (loud annoying pops and clicks) then reduce the dynamic range using the s/n dial just far enough until the clipping stops. The lower the s/n the poorer the sound quality so keep it as high as possible without getting clipping.
