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 made by two devoted users.

Listen to a few samples of what you can do with SynthFont:
Here are nine arrangements of some more or less well-know tunes put together by SynthFont users Charles Perry (CP) and John O'Rourke  (JOR). John has recently made some new tunes. Says John: I was wondering if you can replace my 3 songs on your webpage with these new ones.  I’ve gotten more creative over the years since I’m using more Soundfonts, VST plugins and other ‘Special effects’ to make new Midi song conversions.
