## fluidLoad

fluidLoad — Loads a SoundFont into a fluidEngine, optionally listing SoundFont contents.

## Syntax

    isfnum fluidLoad soundfont, ienginenum[, ilistpresets]

## Description

Loads a SoundFont into an instance of a fluidEngine, optionally listing banks and presets for SoundFont.

## Initialization

isfnum -- number assigned to just-loaded soundfont.

soundfont -- string specifying a SoundFont filename. Note that any number of SoundFonts may be loaded (obviously, by different invocations of fluidLoad).

ienginenum -- engine number assigned from fluidEngine

ilistpresets -- optional, if specified, lists all Fluidsynth programs for the just-loaded SoundFont. A Fluidsynth program is a combination of SoundFont ID, bank number, and preset number that is assigned to a MIDI channel.

## Performance

Invoke fluidLoad in the orchestra header, any number of times. The same SoundFont may be invoked to assign programs to MIDI channels any number of times; the SoundFont is only loaded the first time.

## Examples

Here is an example of the fluidLoad opcode. It uses the file fluidLoad.csd and 07AcousticGuitar.sf2.

Example 314. Example of the fluidLoad opcode.

    i 99 0 60      ;play virtual keyboard for 60 sec.
    e

    </CsScore>
    </CsoundSynthesizer>

The output should include a line like this:

    SoundFont:   1  Bank:   0  Preset:   0  Seagul Acoustic Git
