I want to fix it, but I'm afraid this is a problem in JUCE. I'll investigate some more though!

And ASIO is unfortunately not an option, there are more apps that have the same licensing problem that I do, Audacity, for example. I could provide it as a compile-time option so the user can build their own version with ASIO support, but I'm legally not allowed to add ASIO support to a binary.

Great you’re looking into this. Let’s see if there is another way besides ASIO.

Thanks for that friendly warning
A fan of the Andrew Belt style of communicating with fellow humans, I see

i feel it's always good to try being mindful of how different people (especially people we're not familiar with) have different styles of communication (also tone of voice doesn't translate well in text 😉)

I was trying to be friendly when I said 'at my own expense' that I had totally overlooked that Pd has an ASIO option. It wasn't to talk only about Pd. That's the point, that Plugdata is built with/on Pd and that I too would like to see Plugdata include the ASIO option. The response to my comment seemed 'rude' and including a smiley face didn't make the comment any less 'rude'. My rejoinder involving Andrew Belt is that he is notorious for being snarky and so rude to anyone, including developers to the project he started--VCV Rack--that some of those developers have left.

Now if you or any of the folks involved with the project would rather I not get involved and comment, then that's fine. I assumed that this area of github would be as friendly as I found my interactions to be with Timothy S on the Electrosmith forum. :) ;)

I meant to be friendly but it was clearly not received like that. When I was writing "The topic here is Plugdata :-)" I meant to keep this particular discussion thread focused on Plugdata and ASIO (or other possible ways of doing multichannel audio with Plugdata on Windows).
I had and have no negative intentions and I think we share the same fascination for using multichannel audio!

thank you sevdh for your explanation.
i am here ONLY to support the Plugdata project. just the other day i was explaining on a youtube video on the chompi (which is a daisy project) on the merits of Plugdata. this is a project worth promoting.

Could you give an example of where to add the asio sdk target? I'm not largely familiar with editing cmakelists and I'm not sure where to put this.

Thanks

I'm away from my dev machine right now but basically, in CMakeLists.txt you'd add a line with JUCE_ASIO=1 under the line set(JUCE_COMPILE_DEFINITIONS (where all the other definitions are) and another line after the line add_library(juce STATIC) containing target_include_directories(juce PRIVATE <MY_ASIO_SDK_DIR>/common), replacing MY_ASIO_SDK_DIR with wherever you've put the ASIO SDK on your computer (You need to download that separately from Steinberg). That's at least the basic idea for getting it running on your machine, although not actually a robust solution since it relies on hard-coded paths.

Fantastic to hear that Steinberg allows GPL3 now.

Done!

Thanks so much for picking this up!!!

It is really fantastic to have this included and be able to work with ASIO multichannel projects on Windows!
