Kontakt 8 Corrupts the OpenGL Context Upon Instantiation

Mark Coniglio

I am a developer creating a VST host on macOS, and I'm using Kontakt 8 VST3 as one of my test plugins.

My app does a lot of video rendering, and therefore must maintain close control of the current OpenGL context. As soon as I instantiate Kontakt 8, my app throws an assertion error saying that the current OpenGL context is not what it is supposed to be.

Note that I do not need to open the UI to cause this problem. I'm just using IPlugProvider to instantiate the plugin for inspection.

The correct behavior of the plugin should be to save the current OpenGL Context at the time of instantiation, and restore it before exiting its functions.

If you are in luck then the N.I. expert due for a leave around now has not yet left and if so then we can ask if @Matthew_NI has any insight and wisdom to share here ?

Else then I am afraid that you will have to contact N.I. Support (all) and ask them for help.

In case that you need guidance contacting support : How to contact NI Support and How to get in touch with our Customer Care

N.I. also do have developer help but that is directed at third party developers of NKS and Kontakt instruments but it is possible that they could also help , I don't know , check the following resources for developer contact information :
