Hello, I have started developing JackSharp, a .NET/Mono binding for libjack. It has been tested on Windows 8.1 and Debian GNU/Linux sid amd64 and i386, but should work on other platforms as well. https://github.com/residuum/JackSharp Not every API call is implemented yet, especially the transport API has not been used, currently there are two main client classes: Client: Use this to create a client with audio and MIDI ports and add a function to the process event. Controller: class for managing port connections. If you want to build a replacement for QJackCtl et al, then use this. This repository also contains a wrapper for NAudio. Of course, this has not been tested or used in real software, so this is still pre-alpha. And I am willing to change the API, as well as take pull requests. Thanks for looking into the code and using it, Thomas -- "When one's home has a really excellent computer capable of reaching other computers anywhere in the Galaxy, one scarcely needs to budge."
