fluidNote — Plays a note on a channel in a fluidSynth engine.
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. It uses the file fluidNote.csd and 19Trumpet.sf2.
Example 292. Example of the fluidNote opcode.
See the sections Real-time Audio and Command Line Flags for more information on using command line flags.
