I did say "in" and not "for", and in the context of discussing a non-permissive license, I think it should be relatively clear about my statement being about incorporating the engine into other software and applications that you may not want to open source. This is why I said side or school projects, because you usually don't care about having to open source those. I did not mean to imply that no professionals use Supercollider to make music and sounds. And really, I was just wanting to point out that Csound can be embedded in several different ways, with a license that is permissive for such uses in proprietary systems.

It's great people are using Supercollider in other ways to make money! But it's obvious that the license doesn't extend to music recordings and performance.

All that being said, do you have any links or descriptions on how you use Supercollider (or any other system)? I'm curious to hear about anything you're able to share.
