soundfont URL

Define the sound font which is used to play the music.

By default, abc2svg uses a sound font extracted from the SF2 font Scc1t2.
This font is split by instrument to reduce the load time and it is base64 encoded into a javascript so that it can be loaded from any HTTP domain. The instruments are stored in the directory http://moinejf.free.fr/js/Scc1t2/ as <instrument_number>.js (<instrument_number> = <bank> * <preset>).

The command %%soundfont changes the default sound font to

• either a raw SF2 sound file.
  In this case, the file must be in the same HTTP domain as the current HTML page.
• or a javascript file containing a base64 encoded SF2.
  Such a file may be loaded from anywhere.

In my site, the soundfonts are stored in the directory http://moinejf.free.fr/js/sf2/.
(the file sf.sh is a shell script used to build the .js files from the .sf2 files)

Example:

X:1
M:6/8
L:1/8
Q:3/8=60
K:Em
%%MIDI program 56 % GM Trumpet
%%MIDI chordprog 78 % GM Whistle
%%MIDI gchordon
B,|"Em"E2G "D"FGA|"G"G2F "C"E2G|"Bm"F2E "D"DEF|"Em"E3|]
