Re: [PD] pd~ set audio API on linux
so I solved it by starting pd processes from the shell and communicating to/from the main patch using OSC. Yes, that's how you would typically manage independent Pd instances.

Re: [PD] pd~ set audio API on linux
Hi, the subprocess outputs "no audio API specified" to its pd window Can confirm on Windows. It's a spurious error message. I just opened a ticket: https://github.com/pure-data/pure-data/issues/1952 It works receiving/sending audio from/to the parent process but in my special use case it'd be even nicer to input/output audio directly to the interface [pd~] is designed to pipe audio through the subprocess. The code does not (or rather should not) allow the subprocess to use a real audio device. Ideally, we should disable the "audio settings" and audio API entries in the "Media" menu for subprocesses, as they don't have any meaning in this context. which works as soon as I specify the audio API in the media prefs of the subprocess. I highly doubt that this actually works.

I don't think it's possible out-of-the-box, but you should be able to use my "mediasettings" library for this. mfg.sfg.jfd IOhannes ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
