@xbix you can also use Open Frameworks with ofxOfelia (or just Open Frameworks and ofxPd): https://puredatagui.handmadeproductions.de/

Thanks, I tried to improve it a lot

Its working - apart from pd.closePatch (it is the ofxPd version from ofxOfelia). Here is an example: https://ofxpdtest.handmadeproductions.de/
The test patch is not mine. Its this: https://forum.pdpatchrepo.info/topic/11405/a-vanilla-patch-i-made-while-browsing-the-internet

I would recommend [Mymembrane~] from Mike Moreno: https://github.com/MikeMorenoDSP/pd-mkmr/tree/master/instruments

Which also means Pure Data works with Ofelia with Open Frameworks with Emscripten with AudioWorklets...

Its quite experimental, but it works and I think its a big improvement:

@Hymnosiac Ofelia. And check out Open Frameworks and Lua.

@ingox Thanks. PdWebParty https://github.com/cuinjune/PdWebParty can do that too, but its a different approach, so I think they compliment each other. I basically just use Emscripten with Open Frameworks and ofxOfelia. But I had to make some changes to make Emscripten work again, and I extended some things (and there is still room for improvement ).

@JackOats Thank you. I will continue to work on the sound synthesis and sequencing possibilities after I fixed the last technical Emscripten issues.

@jaffasplaffa Thank you. Couldnt test it on a Mac by myself yet (I heard Macs do handle audio quite well...).
Recording should be possible (in theory).

I posted the Emscripten Website which is based on a Pure Data / Ofelia patch some time ago.
But I made some improvements and would like to get some feedback if there is a large audio latency or if there is a lot of audio distortion with certain browsers, os or devices: https://simplesequencer.handmadeproductions.de/
My experience is, that it works well with the current audio buffersize of 2048 with Firefox and Chrome on my desktop computer (Linux and Windows), and with some distortion on my Android smartphone.
