Re: [fluid-dev] Fluid synth channel 10

Hi David,

you need to change the channel type of that channel, by calling:

fluid_synth_set_channel_type(synth, 9, CHANNEL_TYPE_MELODIC);

After this, fluidsynth will treat all program change events for channel 10 as 
it does for the other channels by default. Note that fluidsynth uses zero based 
counting of channels, so its channel 9 here.

Also make sure to select your personally preferred bank selection mode with the 
"synth.midi-bank-select" setting:

On every program change, fluidsynth tries to find a preset that the soundfont 
provides. For drum channels it tries bank 128, which is why percussion 
instruments keep being selected.
