Thanks again for your help Tom. It's all working now!
For the benefit of anyone else wanting to set a percussion channel other than
9, and have 9 as melodic, the following seems to be the minimum number of
steps. (For clarity I'm omitting the checks on the success of the various
calls.)
===
// I want 65 channels:
settings = new_fluid_settings();
fluid_settings_setint( settings, "synth.midi-channels", 65 );
// create the synthesizer
// with percussion channel = 64
// and set the traditional MIDI percussion channel (9) to melodic:
synth = new_fluid_synth( settings );
fluid_synth_set_channel_type( synth, 64, CHANNEL_TYPE_DRUM );
fluid_synth_set_channel_type( synth, 9, CHANNEL_TYPE_MELODIC );
// create the audio driver
adriver = new_fluid_audio_driver( settings, synth );
// Load the sound font:
int nSfId = fluid_synth_sfload( synth, pszSoundFontPath, TRUE );
// Set voice 0 on channel 9, which should now be melodic
fluid_synth_program_select( synth, 9, nSfId, 0, 0);
===
The last step, after loading the sound font, turns out to be the crucial one I
was missing from the start. Before any NoteOn's are sent to channel 9 it will
receive a program change with
fluid_synth_program_change( ... );
to set the voice which is actually wanted. Nevertheless the initial
fluid_synth_program_select() seems to be crucial. Thanks again for the
excellent support!
