Hello Louis,

Quoting "Louis B." <address@hidden>:

Hi All,

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

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

  /* 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.
