Bumping a topic on the forum doesn’t do anything to change its priority in our development plans. We know many users are looking for features like this.
Building synchronization features between Dorico and Cubase is complicated because it requires changes not only to Dorico but also to the shared audio engine (which requires us to compete for the limited development time of some of the senior developers who are working on many other projects within Steinberg), and if we want to go further than MTC, which we may well in future, it would also require deeper changes within Cubase itself. So it is a complex area of development and requires us to align our product and development plans carefully.
