[PD] [pd~] subprocess: unknown audio API specified

I don’t know what I’ve done differently, but I’m able to get audio out of the pd~-subprocess now, even though I’m still getting the ‘unknown api’ error.

So I’m back to blaming my synth’s subprocess for not getting its audio to the outside world, and need to dig in further.

Thanks for the suggestions and feedback.

Hi Phil,

 first set its audio API to portaudio, then switch DSP on?

I tried that, and still get no sound output.
But, do you have the "unknown API error" on the Pd window?
If not, check the in/out channels on the subprocess' Audio Settings menu and set them to match your system.

I would also "Save all preferences" (or "save to" if you need them in a file) after finding the correct settings.
