Csound has the opcodes --

If you've got the examples working, you should be able to put together a .csd file that'll let you use them
[At least, I have tested those example and they work. I haven't tested the .csd and instrument codes I'm putting into my own usage, because that's going to be complex, takes time I don't have to write -- & isn't ready to run yet.]

Those opcodes include:
fluidAllOut — Collects all audio from all Fluidsynth engines in a performance
fluidCCi — Sends a MIDI controller data message to fluid.
fluidCCk — Sends a MIDI controller data message to fluid.
fluidControl — Sends MIDI note on, note off, and other messages to a SoundFont preset.
fluidEngine — Instantiates a fluidsynth engine.
fluidLoad — Loads a SoundFont into a fluidEngine, optionally listing SoundFont contents.
fluidNote — Plays a note on a channel in a fluidSynth engine.
fluidOut — Outputs sound from a given fluidEngine
fluidProgramSelect — Assigns a preset from a SoundFont to a channel on a fluidEngine.
fluidSetInterpMethod — Set interpolation method for channel in Fluid Engine
[& this more low-level stuff  that gives you more specific control over subsequent processing]:

sfilist — Prints a list of all instruments of a previously loaded SoundFont2 (SF2) file.
sfinstr3 — Plays a SoundFont2 (SF2) sample instrument, generating a stereo sound with cubic interpolation.
sfinstr3m — Plays a SoundFont2 (SF2) sample instrument, generating a mono sound with cubic interpolation.
sfinstr — Plays a SoundFont2 (SF2) sample instrument, generating a stereo sound.
sfinstrm — Plays a SoundFont2 (SF2) sample instrument, generating a mono sound.
sfload — Loads an entire SoundFont2 (SF2) sample file into memory.
sflooper — Plays a SoundFont2 (SF2) sample preset, generating a stereo sound, with user-defined time-varying crossfade looping.
sfpassign — Assigns all presets of a SoundFont2 (SF2) sample file to a sequence of progressive index numbers.
sfplay3 — Plays a SoundFont2 (SF2) sample preset, generating a stereo sound with cubic interpolation.
sfplay3m — Plays a SoundFont2 (SF2) sample preset, generating a mono sound with cubic interpolation.
sfplay — Plays a SoundFont2 (SF2) sample preset, generating a stereo sound.
sfplaym — Plays a SoundFont2 (SF2) sample preset, generating a mono sound.
sfplist — Prints a list of all presets of a SoundFont2 (SF2) sample file.
sfpreset — Assigns an existing preset of a SoundFont2 (SF2) sample file to an index number.

Hi Spencer,

Previously I only got the chuck_dl error 126. I don't know what's happened, but Chuck does load the chugin now. However, it doesn't work: it doesn't have any of the functions related to FluidSynth (at least 'open' or 'noteOn'). That said, I'm unqualified to even compile these things properly, so I wouldn't go looking for bugs based on my strange process of getting the chug file to appear.

Hi Pietari,

Glad to hear of your interest in working with FluidSynth and ChucK. The main FluidSynth chugin works fairly well on Mac OS X and Linux (last I checked) but I have not yet tried to port it to Windows. Heavyweight chugins like FluidSynth tend to be harder to develop and maintain for multiple platforms, as each system has its own eccentricities with build systems and linking to external libraries. 

If you can post the log output from the console when that error occurs, that would be helpful, as maybe it is a straightforward error to fix.

Hi! The Extend section of the Chuck site describes a FluidSynth chugin for
using soundfonts. CCRMA does have code for this chugin (https://github.com/ccrma/chugins/tree/master/FluidSynth), which I managed to
compile for Windows after many, many hours of effort. Unfortunately, I get
a chuck_dl error 126 when Chuck tries to load the file (I had to change
the message level), so either my frankly ridiculous compiling process
broke it or the code doesn't work right now.

Does anyone have this chugin in working form?

Pietari Seppänen
