Syntax

isfnum fluidLoad soundfont, ienginenum[, ilistpresets]

Description

Plugin opcode in fluidOpcodes. This opcode is part of the plugin repository and has to be installed separately. The plugin repository can be found here: https://github.com/csound/plugins

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.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac   -+rtmidi=virtual  -M0    ;;;realtime audio out and realtime midi in
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
;-o fluidLoad.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

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

giengine fluidEngine
; soundfont path to manual/examples
isfnum	 fluidLoad "07AcousticGuitar.sf2", giengine, 1
	 fluidProgramSelect giengine, 1, isfnum, 0, 0

instr 1

	mididefault   60, p3
	midinoteonkey p4, p5
ikey	init p4
ivel	init p5
	fluidNote giengine, 1, ikey, ivel

endin

instr 99

imvol  init 7
asigl, asigr fluidOut giengine
       outs asigl*imvol, asigr*imvol

endin
</CsInstruments>
<CsScore>

i 1 0 2 60 100 ;play one note from score and...
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
