As per the LGPL (see, I am releasing under the LGPL the source code for the MIDI library used by Musical, which is based upon Tritonus (

The project is designed to provide a MIDI file (SMF) reading and writing library (since Android doesn’t include Sun’s javax.sound.midi implementation)

There is very little additional code compared to the standard Tritonus implementation.  I have mostly just removed all the standard waveform audio code and left only MIDI-related classes.  There were also some minor modifications requires to compile under Android.
