@CHEXHOmusic Have you setup your ilok with your PACE developer account? This should provide you with a link to their documentation that guides you through building the SDK and the demo plugin. Once you have the demo plugin working you should have no problem building your own.

We are limited with the guidance we can give here due to the NDA, but basically PACE/AVID documentation provides everything you need beyond putting the SDK in the tools folder.

you dont need a PACE account or their documentation to compile the AAX SDK, and thus compile AAX plugins in HISE - but you will need t to authenticate your plugin so it runs in ProTools.
