fluidNote — Plays a note on a channel in a fluidSynth engine.
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
Plays a note at imidikey pitch and imidivel velocity on ichannelnum channel of number ienginenum fluidEngine.
ienginenum -- engine number assigned from fluidEngine
ichannelnum -- which channel number to play a note on in the given fluidEngine
imidikey -- MIDI key for note (0-127)
imidivel -- MIDI velocity for note (0-127)
Here is an example of the fluidNote opcode. Play fluidNote.csd and 19Trumpet.sf2
