fluidProgramSelect — Assigns a preset from a SoundFont to a channel on a fluidEngine.
Plugin opcode in fluidOpcodes. This opcode is part of the plugin repository and has to be installed separately. The plugin repository can be found here: https://github.com/csound/plugins
Assigns a preset from a SoundFont to a channel on a fluidEngine.
ienginenum -- engine number assigned from fluidEngine
ichannelnum -- which channel number to use for the preset in the given fluidEngine
isfnum -- number of the SoundFont from which the preset is assigned
ibanknum -- number of the bank in the SoundFont from which the preset is assigned
ipresetnum -- number of the preset to assign
Here is an example of the fluidProgramSelect opcode. It uses the file fluidProgramSelect.csd.

Here is another more complex example of the fluidsynth opcodes written by Istvan Varga. It uses the file fluidcomplex.csd.
