Hi, I was thinking of an open source model you could try. I have seen a couple of open source projects where the source code is freely available, but community contributions aren't allowed. One such software is a wave table synth called Vital. The maintainer does upload sources on github but does not accept pull requests.
I was wondering if Orion could adopt a model like that. People can see the source code and fork it if they want to, but the Orion team can ignore pull request from the community.
For example, you could make a public github mirror of your private git repo. If anyone says anything on github, it'll be ignored, while you can work as you normally would in the private repository.
