Although I agree with Steven that Csound should not be written to output SoundFonts, the Python scripting capability of Csound 5 should make it possible to write a Python script to do what you want, or at least PART of what you want.

There may also be Python libraries for building or editing SoundFonts. Possibly, FluidSynth can do this.

You can embed Csound scores and orchestras in Python code, so you should be able to make a single .py file that:

1. Loads a patch.
2. Renders notes of various pitches and velocities to named soundfiles.

If there is indeed a Python library for making SoundFonts, you can go further:

3. Creates a SoundFont for your patch.
4. Loads the computed soundfiles into your SoundFont.
5. Saves your finished SoundFont.

Hope this helps,
Mike

Hi R.D.,

I think that the idea of outputting SoundFonts directly from csound is
not quite in line with the nature of Csound.  If someone was to build
a soundfont building opcode library and distributed it themselves I
think that'd be fine, though I really think the architecture for
something like this would be better served by an external program
driving csound to make individual samples, and then the external
program itself collecting the generated samples and building the
soundfont.  I'd guess it'd be the same work to do the soundbuilding
code within Csound as it would be externally anyways.
