Vasparittya [pronounce something like "wash-par-it-ya", meaning: iron-sling] is a tool for easily playing custom sound effects with any kind of input device available to a Windows PC. This includes: keyboards, mice and any DirectInput or XInput compatible joystick devices.
Custom sound effects are have to be edited and programmed by you. The programming part is made easy by using xml files. For examples, see default sound banks.
The sounds used in the default sound banks are copyrighted property of JoWooD Productions Software AG, id Software, L'art pour L'art társulat, and various unknown groups, and thus they are for personal use only!
Now you can turn anything into a piano. Just extract it next to the 'Vasparittya.exe'. You need to restart the app for the files to be loaded.
