SynthFont - 1 and 2

SynthFont (free V.1 and paid V.2) 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. A midi file is different from - for instance - an MP3 file in that the file does not contain any audio data. Instead, the file is a collection of notes and instructions for how to play them. SynthFont combines this data with the audio data in a SoundFont to produce ("render") an audio version of the song. Here are a few audio samples in MP3 format for you to  listen to.

Version of SynthFont2 and  SynthFont2x64 released December 7th, 2021, is available. Get it now!

Version 1.760 of the free SynthFont1 released September 4th, 2021, is available. Get it now!
