Hi there, I think this is a very nice list of features overall, but I've also selected a few that I think are more important. And also, I will add a few more:
1. Parameter linking/modulation for every single setting in a plugin, PC module, channel, or bus. This will allow for a vast range of possibilities for mixing setups and options.
2. Enhancement of Routing-Patching capabilities. I think for this one the devs can take some inspiration from Reaper's routing options. In my experience, they are superior and they allow for invaluable flexibility and faster workflow, so it would be great if Cakewalk had similar options as well. I think they would be well-paired with Cakewalk's own patch points. And this brings to the next suggestion:
3.Adding a virtual Patch-bay. This would give us the option to view and edit all the routing options of the whole project in one place, and would also make it easier to see what's going on and change the routing. I think the patchbay would also make patch points easier to use, as it would provide a visual representation of what's happening behind the scenes. It should also allow us to patch anything to anything else, be it channel, bus, hardware input/output, plugin or PC module.
4.More options for aux sends, such as the ability to flip the polarity for a send.
The above suggestions were actually inspired by Dan Worrall's mixing tips videos, but I think having these options would be useful for every music produce/engineer and would make Cakewalk a much more powerful DAW than it currently is.
PS: I also think it would be a perfect addition to the new Sonar, encouraging more people to buy it (or at least me personally, if all the above features are integrated on Sonar, I would definitely like to pay for it).
