The program is very easy to use, and a trial version is available. It also allows you to embed a player, and has a number of other features. It does not rely on your sound card with regards to the quality of the final output, so you can expect high and consistent quality, regardless of what sort of computer you are going to use it on.

You can choose an appropriate SoundFont for every MIDI file, or even supply each instrument of your composition with an individual SoundFont (piano, guitar, trumpet etc.). MIDI to MP3 Converter includes an editor for controlling ID3 tag information in the output files. The program also offers a number of sound effects.
