Hello!

I’m attempting to use the pd~ object for the first time on a Raspberry Pi, with the idea of taking advantage of the multiple CPU cores.

I’m using a Pi 3 with the latest 64bit “headless” OS, running Pd 0.53.1 (installed via apt-get). My understanding is that using the pd~ object should run each instance of a patch on a different core of the Pi.

Here’s the test patch: https://github.com/yannseznec/multicoreTest

On the command line, i'm attempting to run the "multiTest.pd" file like so:

pd -nogui multiTest.pd

Pd launches and it gives me the message "pd~ version 0.54" but there is no sound.

Running only the subpatch (rand_osc.pd) produces a single sine tone as expected.

Am I using the pd~ object incorrectly, or misunderstanding something about how this should all work?

Thanks!

Yann
