The old Trilogy works on Cubase 10. Rough installation using jbridge. The Trilogy instrument panel opened really small with no instruments visible for selection. So I closed it and opened it and closed it and opened it 3 or 4 times and all of a sudden to my surprise Trilogy opened with an instrument panel and all. It works fine until you close Cubase. When you open Cubase again, Trilogy will open only after you close the instrument panel and open it and close it and open it several times. Then when it finally opens, you can use it like before. Don’t as why, just use it. There is no way to go back and use Trilogy as you did in the past. Just swallow the inconvenience and use Trilogy once it opens properly.
