A free program for Android, by GamesGreh.

SoundFont is a free application to play SF2 files on Android mobile devices. It allows you to play the file with your custom instruments and allows you to listen to music.

It is based on the SoundFont engine, which is an open-source project, that allows you to have your music player. The application has a very simple user interface, which allows you to change the volume, switch between songs, and use the buttons to play or pause music.

You can choose from a list of sound effects that will modify the sound of the instruments in the file. For example, you can add a reverb effect, a chorus effect, or a metallophone effect.

SoundFont allows you to record a song and play it back to yourself. You can also export the sound file to an OGG format.
