Yes - the command-line tool will take a SOUL patch and emit a full, ready-to-build JUCE project that will create all the plugin formats (and a standalone app).

Wait , does that mean I need to install the whole build chain ?

Anyway to do that in a Docker container, maybe a ci/cd pipeline where I can just push my code and get an VST as a build artifact.

If you want to build the resulting JUCE plugin on Github Actions, you can borrow my workflow code https://github.com/maxwellpollack/juce-plugin-ci

How exactly do I use this ? Do I for it and then setup my own pipeline

Yeah, at the moment you need to build it. Our ambition is to eventually offer that as a service via soul.dev so you can just download a binary.

Sounds great, if I could just upload a solo file and then have a binary pop out I'd easily pay 10 or $20 a month for the privilege
