Consider it done.  Thanks for pointing this out.

Yep, chaining the example I think would be a good idea as this I think
that is a better default (as I followed the example rather blindly
when writing my code -- but it was _very_ easy to integrate with Piano
Booster) Starting up fluid synth is then more like turning on a
hardware synth -- you always hear a sound even if you don't send a
program change first.

Hello Louis,

Hi All,

I have another small change I would like to see in the next release  if

when commenting out the following line 51 from example.c no sound is

 /* Select bank 0 and preset 0 in the SoundFont we just loaded on
    channel 0 */
 //fluid_synth_program_select(synth, 0, sfont_id, 0, 0);

I believe that the system should default to bank 0 and preset 0 when a
sound font is first loaded. Some midi files forget to set a preset
especially single piano pieces. This caught me out a few times and I
had to add the following code to my start up.
   for (int channel = 0; channel < MAX_MIDI_CHANNELS ; channel++)
       fluid_synth_program_change(m_synth, channel, GM_PIANO_PATCH);

However the standalone version of fluidsynth does not have this
problem and defaults to preset 0.

I think it does default to bank 0 preset 0 on all channels.  The issue is
actually with the fluid_synth_sfload() call in the example code.  The 3rd
parameter is called reset_presets.  If its FALSE then no instrument changes
are made on any MIDI channels.  If TRUE then all MIDI channels are refreshed
(as if they had bank/program change messages sent) which may cause new
instruments to get used from the loaded SoundFont.  Perhaps the example
should just be changed to pass TRUE as the 3rd parameter.
