VSFManager (short for Virtual SoundFont Manager) is an interactive tool for dynamically loading, managing and creating SoundFont files. It works completely transparent while you work with any other MIDI sequencer.
With it you may load/unload/change presets in real time while you work with your favorite sequencer, and create sound packages (SF2 or VSF files) for every single composition that you make. 5 preset slots and max 100 files in files cache. Version 3.2 may include unspecified updates, enhancements, or bug fixes.
