[fluid-dev] Percussion Channel

[dave]

Hi Everyone,

I'm new to FluidSynth and have hit a problem with percussion.

I want to play pieces with up to 64 parallel 'strands' of music, one of which 
may or may not be percussion.    FluidSynth's ability to let me have up to 64 
different voices playing back on up to 64 different channels is a big 
attraction.

So my plan was:
Allow 65 channels and set no 64 (counting [0...64]) to percussion.
Play strand N on channel N  (in [0-63]) unless it is percussion, in which case 
play it on channel 64.

Unfortunately the strand playing on channel 9 (the traditional MIDI percussion 
channel in [0,15]) plays as percussion.   So I explicitly told it not to with:  

        settings = new_fluid_settings();   
        fluid_settings_setint( settings, "synth.midi-channels", 65 );
        
        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 );

        adriver         =  new_fluid_audio_driver( settings, synth );           
              

and stuff sent to channel 9 *still* plays back as percussion.    Have I done 
something wrong, or is this a bug?
