The latest release of mobileTunes takes advantage of Ben Ryves' QuadPlay routines combined with the GUI power of Doors CS 6 for a superior media experience. Play up to 4-channel MOD music and audio on your calculator through the I/O port while taking advantage of Doors CS's ability to open songs in the associated player simply by clicking on the song. Four sample songs are included plus documentation on how to make your own.
In addition, I have an online tool that attempts to convert MIDI files to mobileTunes 3 songs. It has greatly improved since it was started, and should be smart enough to produce recognizable songs.
