Hi @mcetilia I started today on patch.init/pd2dsy. I get that error every time I flash my patch.init by my patches still work.
I get a high-pitched whine when there is something wrong with my patch. For example if I use an unsupported object (see the list of supported objects) or if I forget an argument. I edit in the PlugData VST plugin running Ableton and noticed the errors there.
I started by just passing through audio from the inputs to outputs using objects that I copied out of the examples. I was able to get knobs to work but not delay.
