The Virtual Sampler Library (VSL.DLL) provides applications running on Pentium-class PCs under MS Windows 9x/ME/NT/2000/XP with a MIDI-controlled, low-latency, fully programmable wavetable module implemented entirely in software. The Virtual Sampler SDK contains the documentation and code needed to use the Virtual Sampler Library in your own programs. It also includes the Mellosoftron, the live, emulated sampler based on the Virtual Sampler Library, for quick sound patch creation and editing. (For size reasons, the VS SDK Evaluation Package and the Mellosoftron are distributed in separate archives. The Mellosoftron archive is available from our site: http://www.polyhedric.com/software/).
