Jaleo is the test platform for the current beta Ruckus, supporting MIDI 
playback using:  OPL2 (9-voice), OPL3 (18-voice, stereo), MPU-401 
(including special support for the Rio & Maui), and the GUS (including 
banks, cache patching, and SuperCache).  That new SB/Emu8000 thing, too.

Features of the test program include:

 - text-based GUI/mouse controlled
 - play list/file manager
 - complete device configuration, from port to LFO effects to bank select
 - SuperCache for loading all GUS patches to extended memory for
   near-instant patch caching (less than two seconds for 1MB)
 - also works in Windows and OS/2 (background/minimized in OS/2)
 - native GUS support
 - special support for Rio/Maui (set voices, read peak levels, etc.)
 - special bank select for GUS (banks supported in all devices)

Now includes detailed info on using it with OS/2.
