#fluidsynth

Qsynth is a fluidsynth GUI front-end application, written in C++ around the Qt framework, using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynths. sourceforge.net/projects/qsynth

fluidsynth -a alsa FluidR3_GM.sf2 wb.midi

Where "FluidR3_GM.sf2" is a soundfont. Wat?

I've been dreaming of a way of making classic NES ringtones for Android.  After futzing around for a little while, I have success!

First thing you will need are the tools.  (I have no idea how to do this in Windows, so good luck with that.)  From your distro's repositories kindly install "fluidsynth" and "lame".  This can be done on Ubuntu with

sudo apt-get install fluidsynth lame

You will need an Android program called ringdroid installed onto your Android device. 

Finally, you will need a "soundfont" file for fluidsynth.  I did a Google search for "best NES soundfont" and came up with: The NES Soundfont

Next thing you'll need is the NES song track you are looking for.  Head over to the awesome website http://www.vgmusic.com and pick a midi file.  You are looking for a midi that SOUNDS the most like 8-bit music.  There tends to be more than one selection for a given track, try a few until you find the one that fits.

Copy the soundfont file to /tmp (or you sf2 folder, /usr/share/sound/sf2/ in Ubuntu)

Copy the midi file to /tmp

Run the command: fluidsynth -F output.wav /path/to/sf2/file input.midi (making the appropriate substitutions on that line)

Now run: lame --preset standard output.wav output.mp3

Take your completed mp3 file and listen to it, if you like the way it sounds continue  following this guide. Otherwise, you will need to pick a different soundfont or a different source midi file.

Copy your completed mp3 to the /sdcard/Music file of your Android device and fire up Ringdroid.  Ringdroid is pretty simple to use and if you've managed to follow this guide up to this point you shouldn't have a problem.  It lets you pick a 30 second snippet of the entire track to set as a ringtone.
