I apologize. I left this conversation because I really have only one piece of music left to finish and I was hoping I could just do so without bothering with Bandlab. I have less than 18 months before the big sleep and I'll be bedridden for some of that but to do what I want to do, I can already see potential issues where driver incompatibilities could force my hand.
However, the advice in this thread is ambiguous. Since I don't know what prompts or choices I'll get when I upgrade and a roll-back or do-over, being highly unlikely, I need to know what to do in more exact terms. For example:
Daibhidh
If you install Cakewalk by Bandlab without uninstalling your previous Sonar Platinum
the new version will not be limited at all. You can use all your Platinum features in the new version
as long as you keep both installations (the old Sonar and the new Cakewalk).
Normally, an upgrade process finds your installation and overwrites those parts that require change. You do not uninstall your current installation even though the process will uninstall some of it for you. By "keep both installations" it appears that overwriting my current installation is not what is being recommended and that I should install Bandlab as a separate installation. How much separation should I aim for? I have 6 SSDs of 1TB each. Should I install on a separate drive? And, how do I get Sonar Platinum's additional features to register in the Bandlab installation if they are separate?
And this is the downside of "Free" that I raised. If I was paying for Bandlab I would demand that they provide the detailed documentation outlining the upgrade process complete with graphics of each prompt, and the outcome of each choice but because it is free I am left to depend upon the kindness of strangers and can demand nothing. While I am pretty sure, almost certain, and quietly confidant that the process itself will make all abundantly clear, the mere possibility that it will not is unacceptable. I just do not have the time to learn Cubase or Pro-Tools from scratch.
