This software uses the "Dynamic Universal Music Bibliotheque" library for MOD music playback. See dumb.txt for original license. The version used, however, has been heavily modified from its original form and is the same version used by the foobar2000 component foo_dumb as of mid-2008, found at http://kode54.foobar2000.org/. ZMusic Lite is a feature reduced version that omits all content that is not compatible with the LGPL v2.1. Use this if your project cannot comply with the GPL. This means that most of the available MIDI synths, except FluidSynth, have been removed and that the playback of native OPL file types is disabled.
