 | When converting from XML to SF2, pysf enabled looping if it found loop
 | points.  The original soundfont file had loop points, and the new
 | soundfont file had looping enabled.  Here is the culprit code. if
 | Loopstart != 0 or Loopend != 0:
 |                     LoopType = 3 # Release
 |                 else:
 |                     LoopType = 0 # None
 |
 | I've updated my working copy of pysf.py to fix this issue.  You can get it
 | at the following URL.
 | http://terrorpin.net/~ben/docs/alt/music/soundfont/pysf-wip/pysf.py
 |
 | If you want to enable looping you will need to add a new key to each zone.
 | <sampleModes>3_LoopRelease</sampleModes>

Very thanks!


I just want to say the pysf.py is one of the most incredible ideas that 
someone could ever have.

Congrats: pysf it's fantastic and it really help us

Cheers,
