## fluidProgramSelect

fluidProgramSelect — Assigns a preset from a SoundFont to a channel on a fluidEngine.

## Syntax

    fluidProgramSelect ienginenum, ichannelnum, isfnum, ibanknum, ipresetnum

## Description

Plugin opcode in fluidOpcodes.

Assigns a preset from a SoundFont to a channel on a fluidEngine.

## Initialization

ienginenum -- engine number assigned from fluidEngine

ichannelnum -- which channel number to use for the preset in the given fluidEngine

isfnum -- number of the SoundFont from which the preset is assigned

ibanknum -- number of the bank in the SoundFont from which the preset is assigned

ipresetnum -- number of the preset to assign

## Examples

Here is an example of the fluidProgramSelect opcode. It uses the file fluidProgramSelect.csd.

    ; For Non-realtime ouput leave only the line below:

Here is another more complex example of the fluidsynth opcodes written by Istvan Varga. It uses the file fluidcomplex.csd.

    <CsoundSynthesizer>
    <CsOptions>
    ; Select audio/midi flags here according to platform
    ;Anna.mid is a midi file, a song by The Beatles and can be found on the internet
    -odac -T -F  Anna.mid;;;realtime audio I/O and midifile in
    ;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
    ; For Non-realtime ouput leave only the line below:
    ; -o fluidcomplex.wav -W ;;; for file output any platform
    </CsOptions>
    <CsInstruments>

    sr = 44100
    ksmps = 32
    nchnls = 2
    0dbfs  = 1

    ; Example by Istvan Varga

    ; disable triggering of instruments by MIDI events

    ichn = 1
    lp1:
            massign   ichn, 0
            loop_le   ichn, 1, 16, lp1
            pgmassign 0, 0
