fluidOut

fluidOut — Outputs sound from a given fluidEngine

Syntax

aleft, aright fluidOut ienginenum

Description

Outputs the sound from a fluidEngine.

Invoke fluidOut in an instrument definition numbered higher than any fluidcontrol instrument definitions. All SoundFonts send their audio output to this one opcode. Send a note with an indefinite duration to this instrument to turn the SoundFonts on for as long as required.

Initialization

ienginenum -- engine number assigned from fluidEngine

Performance

aleft -- Left channel audio output.

aright -- Right channel audio output.

Examples

sr = 44100
kr = 4410
ksmps = 10  
nchnls = 2
0dbfs = 32767
