SynthFont is a program for editing and playing midi files using various sound source files like SoundFonts, GigaSampler files, SFZ files and more. VST instruments can also be used instead of a sound source file. The result can be played back through a sound card or written to wave files. With SynthFont you can also create audio files (WAV, MP3, OGG, APE, FLAC) from your MIDI files. SynthFont´s main sound sources are SoundFonts, but also wave files, DLS and GIGA files - and now also VST Instruments - can be used.

SynthFont supports the use of both VST effects and instruments. SynthFont has some basic SoundFont editing capabilities and also shows the MIDI data in a Piano Roll and an Event list. A stand-alone VST instrument version of SynthFont is also available.
