...NetPD Drone Day Special is streaming live to http://netpd.org:8010/live.mp3 now

Hi all,
Saturday 27th of May is Drone Day ( https://droneday.org/ )
I thought I'd start a thread for anyone wanting to do something for it.
Along with a few other netpd users I am hoping to get an all day drone going on over the internet that will evolve slowly and be shaped by whoever wants to log on and join in. The sound will hopefully also be streamed live - I'll give a link nearer the time.

Mike Moreno has made these Euclidean rhythm things based on the Stutter patch I think...

thanks! it would be great to get something like springsound http://www.anckorage.com/spring-sound/ in pd. combining a few spring models in a chain can produce an enormous range of possibilities.

It's not obvious!

Routing MIDI internally requires a 'virtual midi driver' which you can set up with something like MidiYoke http://www.midiox.com/ or LoopMidi http://www.tobias-erichsen.de/software/loopmidi.html
I'm not on Windows so I can't give you anything more specific.

For routing audio you might need something like Jack https://jackaudio.org/downloads/ or Virtual Audio Cable https://vb-audio.com/Cable/

I believe you could make a virtual instrument or effect out of a Pd patch using Camomile https://github.com/pierreguillot/Camomile - then it would appear as a VST instrument in Cakewalk.
Another option would be to route the sound from Pd into an audio channel on Cakewalk but I don't know how internal audio routing works on Windows.
Or (least complicated but maybe less interesting) you could of course just sample the sounds you make in Pd and collage them together in Cakewalk or perhaps load them up as samples in a virtual sampler instrument.

Just in case anyone is having similar problems here's what I've done:
I had an old USB 'iMic' kicking around (USB mic/line in and jack output) which I've plugged in. Selecting that for input and output instead of the built-in mic and output keeps the coreaudiod activity down to a more reasonable 6%. So I assume something is going wrong between Pd, the coreaudiod driver/component thing and the built in mic/output.

@whale-av thanks for your reply. I don't think I have a feedback loop as I only have the standard input/output setup of built-in microphone and built-in speakers with the normal internal soundcard. If I switch the input/output to none in the Pd settings the 'coreaudiod' does stop gobbling the CPU but beyond that I don't know what I can do to sort out the root cause.
