Thread: [OMPT-svn-commit] SF.net SVN: modplug:[788] trunk/OpenMPT (Page 13)

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Revision: 788
          http://modplug.svn.sourceforge.net/modplug/?rev=788&view=rev
Author:   saga-games
Date:     2011-01-16 21:39:44 +0000 (Sun, 16 Jan 2011)

Log Message:
-----------
[Fix] Sample Editor: rev.781 broke the Downsample button. It was allocating too much memory (if it actually succeeded in requesting it).
[Imp] Sound Setup: For ASIO devices, only supported sampling rates are now shown.
