 MID_UTIL - Midi type 0 file utility programs   
 --------------------------------------------

 Version 1.0 Apr 1994
 --------------------
 These 4 programs will process midi type 0 files and make cosmetic changes
 without, in most cases, altering the way the file sounds. The processed file 
 produced is called NEW.MID and saved in the same directory.

 ONETEMPO.PRG will convert all absolute tempo changes to the one constant tempo
              and rescale all delta times (clocks between events) accordingly.
              It is useful when running the sequencer from a constant tempo
              source.

 QUANTMID.PRG quantizes the file as specified by the placement of control 99  
              events, and adds absolute tempo events to honour the original 
              timing (providing at least one absolute tempo event is already 
              present).
              This is useful for making a file print in quantised form without
              affecting the way it plays.

 CTL_TRIM.PRG trims the notes out of the file wherever a specified control 
              event is zero. If the control event, for example, controls the 
              volume, then the resultant midi file should sound the same as 
              the original file.

 REMV_SUS.PRG removes all sustain events (control 64 events). The note off 
              events are moved to emulate the effect of the sustain events. 

 Version 1.1 Apr 1995
 --------------------
 Bug fixed in QUANTMID.PRG (timing was not honoured if tempo changes present).
 Can now exit program with a mouse click.
