I’m one of the developers of n-Track Studio, a cross-platform Digital Audio Workstation available for Mac, Windows, iOs and Android (www.ntrack.com).
The new beta version of n-Track Studio 8 now include a new VST3 to allow to load and use Pure Data patches inside the workstation.
The VST3 is based on libpd and it's included in both Mac and Windows version.
If you want to test it and I have prepared a temporarily FAQ page to help user to create compatible pd patch and test them in n-Track Studio:
I hope you’ll enjoy our project to make a new tool for the Pure Data community and every feedback could be useful!
