fluidNote — Plays a note on a channel in a fluidSynth engine.


fluidNote ienginenum, ichannelnum, imidikey, imidivel


Plugin opcode in fluidOpcodes.

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 338. Example of the fluidNote opcode.
