Has anyone managed to get gdpd working? https://gitlab.cristal.univ-lille.fr/mint/godot-addons/gdpd
Attempted to run the example on macOS, Windows and Linux but could never get the sound working

I'm prototyping a sequencer using Max and Godot, but would like to distribute a cross-platform standalone version in the future. If GodotPD won't work, porting everything to Ofelia seems like the best option

@ostorni Sounds very interesting, but never used gdpd. In my opinion Ofelia with Emscripten is relatively painless regarding some basic stuff, but it has its quirks (mainly due to using Open GL ES instead of Open GL) and issues that are solvable with enough experience, I guess (some things I just do not understand...). Still, it has a lot of potential if its developed further (I started to implement WebMIDI for example, which works quite well, but is coded in a messy way)... Also audio latency could be improved using AudioWorkletNode instead of ScriptProcessorNode... I think there are also some issues with the current OF / Emscripten combination, that are possibly solved in the future (already opened a few Github issues)...

@ostorni redarding audio latency: this is the shortest audio latency without artifacts that seems to work for me, sadly its still around 100-200 ms (also depending on the complexity of the patch)... Its really nice that the Pure Data audio stuff can run in a browser, but would be much better if the latency could be improved...

Here is something about the (not yet implemented) audioWorklet technology, which sounds quite promising (not sure, if OF could be a another bottleneck in this case): https://hacks.mozilla.org/2020/05/high-performance-web-audio-with-audioworklet-in-firefox/

Another drawback: While it seems to work very well on my desktop computer, my Android phone seems to be too slow for the Emscripten stuff...

I am interested in working with Godot (I am already using PD in Unity). This seems like a good repo, haven't tested it yet:
