As I already stated on that very old post, it is a feature request, this is the current state of things:
The EuCon remote controller 3 API3 has been implemented since Cubase Pro 8 and Nuendo 7. That doesn’t mean that all features of the API have been implemented into CUBENDO it just means that now all the new features can be implemented. There are many features on the list, one of them is the “Hiding tracks feature”
Also please have in mind that For the EuCon version 3 the installation requires a 64-bit operating systems. Since Cubase 8.0.20 and Nuendo 7 the new EuCon API3 is in use. Please note that the API3 supports 64bit applications only! According to Avid, no 32-bit support is planned for any future release.
At the moment we have implemented some, but others remain in the to do list or are currently OUT OF SCOPE because other have priority.
In conclusion we have the list of all the new supported features that can be implemented with the new EuCon API 3 and we have already implemented the foundation and achieved the first steps to start adding functionality.
