## Syntax

    fluidNote ienginenum, ichannelnum, imidikey, imidivel

## Description

Plays a note at imidikey pitch and imidivel velocity on ichannelnum channel of number ienginenum fluidEngine.

## Initialization

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)

## Examples

Here is an example of the fluidNote opcode. It uses the file fluidNote.csd and 19Trumpet.sf2.

Example 314. Example of the fluidNote opcode.
