No parameter sliders after load

[martblek]

I don't know if it's a mistake, but if I save a patch with parameters for VST compilation, then when I upload it later, the parameters don't appear and they need to be defined again. If I have many @hv_param parameters it is tedious. thanks

Ah you mean the Automation Parameters in the plugdata sidebar?

I actually almost never used these myself, but I believe the issue is that these are not saved with the pd patch.

They are part of the plugdata state and are only saved in plugin mode together with the entire plugdata state in your DAW session. But this of course doesn't work for standalone.

There was some discussion to have like a "project mode" in plugdata where such states could be saved/retrieved. Likely you don't want the same parameters for every patch/instance, but only for your specific project.

Thanks for answer. We are talking about compiling a patch to a VST3 plugin from the standalone version of Plugdata. I have a working patch and I want to export it as a binary VST3 plugin. So I replaced all sliders with automation parameters. I can't see it now :(

Regarding the use of the Plugdata vst version in the DAW, the parameters are saved there and when loaded, they are shown and work, but there is another problem, namely that the automation names are not updated. video here

Yes as I said for standalone the plugdata state is not saved anywhere, so these automation parameters have nowhere to go between sessions.

For plugin version this is a different issue, but looks like a bug that could be solved (at least for some plugin formats).

Ok thanks. so we can close it.

[dromer]

No don't close the issue. Have @timothyschoen look at these things first :)

So after weeks of scratching my head on this (no documentation or reference to this, that is searchable) it works out that once you have created your [param param1] object on the patch you are developing. Instantiate it in the right hand automation panel by adding a new param and it should automatically link to that param param1 object. To save the right hand side panel params in the automation panel, go to file and hit "export workspace" and lo and behold it loads those automation setting back again. Seeing that automation is probably one of the most core features of any plugin system in a DAW, it is really unfortunate that this vital piece of information is missing from the documentation. The only caveat is that there is no import/export workspace in the iOs AU plugin mode.
