# Chapter 6. Credits

KMidi uses Tuukka Toivonen's TiMidity 0.2i engine Copyright (C) 1995 Tuukka Toivonen. In fact, an enhanced version of Tuukka's original program with five other alternative user interfaces is included with the KMidi distribution. (See below for information on compiling TiMidity.) KMidi and TiMidity use AWE SoundFont extensions done by Takashi Iwai and AMD InterWave extensions done by Greg Lee, which enable you to use SoundFonts (.sbk/.sf2 files) and IW patchsets (.fff/.dat files) in addition to Gravis/Forte .pat files.
