I'm trying to make an app that can play different midi files at the same time. The files would not be streaming and I would like to include them in the apk.
A maximum of 12 would be played at the same time... Mp3 or a combination of both would also be a suitable substitute but for now midi would be ideal.
Is this at all possible? Thanks in advance to the stack-overflow geniuses! :)

One easy way to play a single sound is to use MediaPlayer. Put your sound files in the /res/raw folder, then call the below method using R constants, e.g. playSound(R.raw.sound_file_name) where playSound looks something like this:
private void playSound(int soundResId) {
MediaPlayer mp = MediaPlayer.create(context, soundResId);
if (mp == null) {
Log.warn("playSound", "Error creating MediaPlayer object to play sound.");
return;
}
mp.setOnErrorListener(new MediaPlayer.OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int extra) {
Log.e("playSound", "Found an error playing media. Error code: " + what);
mp.release();
return true;
}
});
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
mp.start();
}
Now, playing multiple sounds at the same time is a bit more complex, but there is a good solution here.
As @uncheck noted, you can use the standard Android MediaPlayer class for MP3, though playing multiple channels at once is a bit tricky.
Android does not have a built-in synthesizer, so if you want to play pure MIDI files through some type of instrument, your best bet would be to use libpd for Android. After that, you can probably find a PD patch with a synth that would fit your needs for the given sound that you're after.
