I tried switching PD patches (didn’t help) but I haven’t tried deleting and reloading Layers. I’ll try that soon and let you know. Thanks for your investigative efforts!
@weichselbaumj I tried your add layer / load pd patch / delete layer / add layer / load PD patch method and unfortunately it didn’t work for me. Still the previous UI layout comes up, and still no sound comes out. I’ll keep tinkering.
I do open up and examine the PD patches that work fine on the Zynthian (grids, 48patches, outer space) and I can’t see what the difference is between these, which work, and mine, which don’t. I’ll let you know if I make progress. However, @ronsum I believe I’m improving my CTLIN installation technique and MIDI CC numbering - thanks for guidance on those.
If you send me the revised zip file you are using I’d be happy to take a look at it.
very useful information on this everyone! thanks very much for the update. my nose is on the grindstone with non-related work to pay the bills but sometime i’m planning on getting a Pi/Zynthian setup and trying to run PD patches on it. so its good to know the progress of running PD patches.
one thing i might suggest is that if the test patch runs it could be that your YAML file is not validated correctly. there’s several sites where you can paste your data and it will tell you if the format is correct for YAML. could be worth a try.
additionally i would not recommend PurrData on Zynthian. at some point you are bound to hit an object that PurrData(L2Ork) supports but vanilla PD doesn’t. all of Martin’s patches were made with vanilla as far as i know, so as long as PurrData didn’t change any of them you should be fine. but don’t be surprised if PurrData can’t open some of them - it’s like 70% compatible with PD vanilla, though i will definitely admit it looks much nicer.
