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 a very beta online tool that attempts to convert MIDI files to mobileTunes 3 songs. It's flaky at best, so be patient with it.
