midi music fade out: how?

[wanwan]

I'm using sun.audio.AudioPlayer class to play midi file in the
representation of AudioStream

I found no built in function that can do a fade out.

I thought about modifying the stream and reduce the amplitude
gradually, but I don't know how to.

Please help.

* That is an obscure class! How did you find out about it?
Why not use some of the (at least publicly documented)
classes from the javax.sound.midi package?

I doubt you will, not without going into the MIDI
sequence itself and altering the note velocities**.
Note that some 'OS level' players cannot alter the
level of MIDI playback because the programmers
either could not, or did not, hook into the sound
card's synthesizer volume control (which is quite
distinct from the channel through which you might
hear MP3's, MPEG soundtracks, WAV's..).

** Though that is a bit of a WAG.

When I google for "fade out midi java", I get
http://jmusic.ci.qut.edu.au/jmtutorial/BandMachine.html which has some
source code demonstrating fading in and out MIDI.

Since you are using a midi file, most sequencer software will allow you
to apply a fade over a specified time. PowerTracks Pro is relatively
inexpensive ($49) and can perform many additional features you may wish
to use later. Alternatively, I haven't used it, but MidiYodi appears to
be a freeware program that can fade a midi file.
